<p class="texte"><B> Day 0 </B><br />
<br>- Make an <i>Escherichia coli</i> cell culture in LB medium overnight<br />
<p><br />
<p class="texte"><B> Day 1 </B><br />
<br/> <br />
- Freeze 0.1 M CaCl<sub>2</sub> and 4 Falcon tubes of 50mL at 4°C<br />
<br/> <br />
- Streak 2% culture in LB to get an OD of 0.3 to 0.4 (it takes approximately 1h30)<br />
<br/> <br />
- Centrifuge 10 minutes at 4500 RPM<br />
<br/><br />
- Remove the supernatant<br />
<br/><br />
- Resuspend the pellet in 7.5 mL of 0.1 M frozen CaCl<sub>2</sub> <br />
<br/><br />
- Centrifuge 10 minutes at 4500 RPM<br />
<br/><br />
- Resuspend the pellet in 500µL of 0.1 M CaCl<sub>2</sub><br />
<br/><br />
- Add glycerol to a final concentration of 15%<br />
<br/><br />
- Keep the tubes at -80°C<br />
</p><br />
<br />
<p class="title1" id="select2"> <I>E. coli</I> transformation protocol </p><br />
<p class="texte"><br />
- Let the LB agar medium plates dry in a sterile area<br />
<br/><br />
- Thaw out the competent cell aliquotes for about 10 to 20 minutes<br />
<br/><br />
- Add 20 to 100 ng of plasmid or 3µL of kit plate DNA <br />
<br/><br />
<i>NB: for kit plate, resuspend the well in 10µL of sterile water</i><br />
- Put the tubes 20 minutes in the ice<br />
<br/><br />
- Put the tubes 2 minutes at 42°C in the water bath<br />
<br/><br />
- Put the tubes back in ice immediately to create the thermic shock<br />
<br/><br />
- Add 1mL of LB medium<br />
<br/><br />
- Put the tube 2 hours in the 37°C water bath (1 hour if it concerns an ampicillin resistant strain) to allow the phenotypic expression<br />
<br/><br />
- Centrifuge for 1 minute at 13000 RPM<br />
<br/><br />
- Remove the supernatant <br />
<br/><br />
- Resuspend in 250 µL of LB medium<br />
<br/><br />
- Streak the final mix on LB agar selective medium: 200 µL on one plate, 50µL on the second plate.<br />
<br/><br />
</p><br />
<br />
<p class="title1" id="select3"> Miniprep and alcaline lysis </p><br />
<p class="texte"><B> Day 0 </B><br />
<br/>- Resuspend 4 to 12 colonies from the plate and name each colony taken on the tubes and on the plate (A, B, C…)<br />
<br/><br />
- Resuspend one colony/culture tube in 5mL of LB medium with antibiotic<br />
<br/><br />
- Let the culture grow overnight at 37°C in a shaking incubator</p> <br />
<br />
<p class="texte"><B> Day 1 </B><br />
<br>- Use the QIAprep spin Miniprep Kit for each culture tube. The last step consisting in the elution of the DNA is made with a hot elution buffer or water at 55°C.<br />
<br/><br />
- Keep the tubes at -20°C <br />
<br><br />
<br />
<br/><I>NB: It is possible to purify the plasmid with an alcaline lysis without any purification column. For 2 mL of culture, 200µL of buffer 1 is added to resuspend the pellet, 400µL of buffer 2 to allow the lysis of the cells and the denaturation of the protein and 300µL of buffer 3 to precipitate the DNA and the proteins. The solution is then centrifuged 10 minutes at 13 000 RPM.<br />
60µL of isopropanol is added to the supernatant and the solution is centrifuged again. The pellet is then resuspended in 100µL of pH 7.4 TE buffer. A part of the contamination by the RNA can avoid by the addition of pH 7.4 TE buffer + 0.2 µL of RNAse. <br />
<br> <b>Buffer 1:</b> Tris 10 mM pH 8 + EDTA 1mM<br />
<br> <b>Buffer 2:</b> NaOH 2mM + SDS 1%<br />
<br> <b>Bufer 3:</b> A COOK 3M + A COOH 15% <br />

Many chemotaxis tests exist such as plate tests or capillary tests. We tried all of them and we decided to optimize the « Capillary essay » from Imperial College 2011 iGEM team.<br />
<br>- Prepare the bacteria in LB medium until they reach an OD between 0.5 and 0.6 (exponential growth phase). This step takes about 5 hours.<br />
<br>- Prepare the multichannel pipette: improve the cohesion between the tips and the pipette with Blu-Tack to avoid air and the possibility of leakage.<br />
<br><br />
<center><img src="https://static.igem.org/mediawiki/2014/b/b1/Installation_1.gif" width="700px"></center><br />
<p class="texte"><br />
<br>- Put 200µl of the different chemoattractants in the wells of the ELISA plate and pipet 15µL of each with the multichannel pipette: galactose which represents our negative control, glucose which represents our positive control and N-acetylglucosamine (NAG). <br />
<br><i>NB: The NAG is the most important test because it is the monosaccharide which composes the chitin on Ceratocystis platani wall.</i><br />
<br> The volume in the tips must be marked.<br />
<br>- Put the tips with chemoattractants in 300µL of the bacterial solution in exponential growth phase in the ELISA plate.<br />
<br>- Let the installation settle for 1 hour at room temperature.<br />
<br>- After an hour, put the volume of the tips on parafilm. <br />
<br>- Each solution is diluted 1/10,000 and 100µL is spread on LA medium.<br />
<br>- The plates are then incubated overnight at 37°C.</p><br />

<p class="title2">Fungicide test: anti-fungal activities</p><br />
<p class="texte"><br />
CAUTION : all the lab equipment must be desinfected before the manipulations with the fungi. <br />
<br>Three different fungus strains were used : <I>Aspergillus brasiliensis, Aspergillus nidulans, Trichoderma reesei</I><br />
<br>- The conidia can be taken by adding one drop of Tween 80 on the fungus plate.<br />
<br>- Then the drop is mixed with 1mL of sterile water in an Eppedorf.<br />
<br>- A microscopy count can be performed thanks to Thoma cell to determine the conidia concentration.<br />
<br><i>NB : The conidia solutions are then diluted and spread on sap medium to get 10,000 conidia/plate.</i><br />
<br>- After 72 hours of liquid culture of the different clones of <i>B. subtilis</i> with the fungicides module, the culture can be centrifugated.<br />
<br>- 130µL of the supernatant is used to soak a pad placed on the conidia plate. The bacterial pellet is resuspended in 130µL of LB medium and also put on a pad. <br />
<br>- The plates containing 10,000 conidia and the soaked pads are then put at room temperature for a few days according to the growth speed of the fungi. Controls are also realized with wild type strains or copper sulfate at 10 and 20mg/mL.<br />
</p><br />
<br />
<p class="title2">Fungicide test: <i>in planta</i> assay</p><br />
<p class="title3">First step</p><br />
<p class="texte"><br />
The first step is related to the inoculation of SubtiTree in plants through stomata (opened in wet condition). <br>We diluted our bacterial samples to get two concentrations: 5.10<sup>6</sup> and 10<sup>8</sup> bacteria per mL. The WT and transformed bacteria are introduced into plants (a control test without bacteria is performed). Thanks to a 1 ml syringe (without needle), the plant was injected with bacteria by pressure. Five leaves of each plant were used, marked with a marker point. It is necessary to repeat the operation on both sides of the leaf and the excess is wipe off. The plants are placed in a growth chamber (phytotron) to control light, high humidity, temperature and bacterial non-proliferation. Bacterial growth in the plant is left for 24 h.<br />
</p><br />
<p class="title3">Second step</p><br />
<p class="texte"><br />
The next step begins with the preparation of the fungal samples. Fungal culture is crushed and mixed with PDB (Potato Dextrose Broth). Then the mix passes through a 100 µm filter (to remove large aggregates) and through a 40 µm filter. The caught hyphae are mixed with PDB for 24 to 48 hours until OD (600nm) 2.5 is obtained. The previously seeded leaves are taken from the plant using a scalpel and placed in boxes above wet absorbent paper (leaves are kept alive for a week). Above each leaf, 5µl of the fungal suspension is deposited (using beveled tips because it is too viscous). As control, we kept inoculated leaves without fungus and leaves with only fungus. Pictures are taken at different times. All the plants are destroyed by autoclaving.<br />

"Ethics is as important as laws."<br />
</p><br />
<br />
<p class="texte">The ethical questioning turned out to be one of the major starting points of our project. Acting on an established environment and modifying it is no mean feat and our thinking combines technical and philosophical point of views. The actual purpose of our project also leads us to undertake an ethical questioning about the role of the scientist regarding “useless” things such as the trees lining the Canal du Midi. </p><br />
<br />
<p class="title1" id="select1">Protection of the beauty</p><br />
<p class="title2">Is it the scientists’ role to protect beauty?<br />
</p><br />
<br />
<p class="texte"> Beauty is a feeling of satisfaction and is selfless. It is more a feeling than the property of a thing, this is not a notion we can clearly understand. Indeed, we can find something beautiful even when we don’t know the purpose of the object...</p><br />
<center><br />
<img src="https://static.igem.org/mediawiki/2014/f/fa/Fontaine_Duchamp.jpg" width="400px"><br />
<p class="legend">Figure 1: Fontaine (Marcel Duchamp). Yes this is also art...</p></center><br />
<br />
<p class="texte">There is always a distinction between natural beauty and artistic beauty according to Hegel, the famous philosopher. The artistic beauty is born from our mind and our spirit: it is an element of signification of the work of art whereas the natural beauty of the object is external. In a way, the Canal du Midi combines both types of beauty: a natural one regarding the nature, the centenary plane trees but also an artistic one since the Canal was built by the human hands.<br />
Usually, science judges beauty as a superficial feature not deserving to undertake any kind of scientific efforts to maintain it. The traditional role of science is to solve global issues and to elaborate complex strategies in order to find useful solutions for everyone’s life. <br />
Once made this observation, one may wonder why synthetic biology would be used only to protect the useless beauty of a local heritage such as the trees lining the Canal du Midi. <br />
</p><br />
<br />
<p class="texte"><br />
This crucial interrogation leads us to consider science and synthetic biology in another way. <B> What if the role of scientists was also to make people rediscovering the beauty of nature? What if the bases of new scientific challenges resulted from a more local scale? </B> Science does not have to be elitist, it has so much to gain opening itself to these challenges. First scientifically, as research is never useless and as we never know the impact and the scope of our results. Then socially, as we could measure the deep interest raised by our project within the population and the media. Adopting a new vision of synthetic biology, we probably make people change their mind about this innovative discipline. <br><br />
The traditional cold objectivity of science distances itself from the society. However, scientists are also beings capable of feeling the beauty, sensitive to the charm of landscapes and <B>able to understand the usefulness of "useless" trees</B>…<br><br><br />
The design of a strategy to protect useless beauty may seem senseless but we believe that it is also the scientist’s duty. We have to remember that the thought is what distinguish <i>Homo sapiens</i> from other species on earth and this thought make us able to understand the world and be conscious of our being (Descartes: <i>Cogito ergo sum</i>). The art is an object of philosophical thought. Consciousness raises humans above all others living creatures. Thus, it is necessary to respect and protect art. And thus, it becomes essential to preserve the beauty of this site. <br />

<p class="title1" id="select2">Human intervention in the nature</p><br />
<p class="texte">Our main questioning aim to understand the complicated relationship between man and nature. Does the mankind have the proper right to operate in nature? Is modified nature considered as artificial?</p><br />
<p class="title2"> Mankind & Nature</p><br />
<br />
<p class="texte"> Nature is known as a creation of God. Human is linked to the nature and for that reason the nature deserves to be respected and loved. Mankind has always been linked to Nature as its survival depends on what comes out of the ground, the trees, the oceans… The nature is a source of wealth for the humankind. It ensures survival and development by giving men the wood, the rocks, the soil to build shelters. Being in contact with nature can allow men to feel strong emotion, as describe by poets like Hugo and Lamartine.</p><br />
<br />
<br />
<p class="texte">Since the birth of humanity, man himself understood well the importance of studying and mastering Nature to develop the civilization. Still today the most advanced technologies often try to mimic natural phenomena. With the development of the civilizations, men modified their environment, changing it for their own comfort depending on their own desire. By increasing their cities and acitvities, humans modify the natural environment. With the industrialization of the societies, the natural environment has suffered from human activities such as waste discharges, oil slicks, intensive fishing but also the introduction of devastating species such as the pathogen,<I> Ceratocystis platani</I>. However, despite these negative aspects, men are capable of favorable actions to help the environment and fix their mistakes. The current trend is to limit the impact of human interventions on the nature, and hopefully this trend is not transient and will not vanish. A new desire is born, a wish to protect the nature and the wildness. Man fits with his position: he takes advantage of the environment and the environment takes advantage of the reasoned human interventions. There is an adaptation of the mankind toward the nature. Moreover, humans have the capacity of empathy: people are able to understand the emotions and cognitive states of other organisms and to identify to them. To respond to these feelings, humans have technological tools allowing them to fight against enemies such as <I>Ceratocystis platani.</I><br />
</p><br />
<br />
<p class="texte">In conclusion, by destroying and hammering the nature, we jeopardize our lives. We need the nature, we come from the nature and we depend on nature for our survival, our food, our discoveries and our civilisation. Respecting, loving and preserving the environment is a question of survival.</p><br />
<br />
<p class="title2">Nature and artifice<br />
</p><br />
<br />
<p class="texte">Talking about the nature refers to the whole world with an exception: all the transformations made by mankind. Thus, the nature consists in the real without all the artificial elements created by humans. The nature is existing regardless of men and his interventions whereas artificial is everything that exists thanks to humans.<br />
</p><br />
<br />
<p class="texte">However, pretending that natural and artificial are opposite does not seem to be true. Man cannot create without elements provided by the nature, he is just transforming the nature, changing the shape. Thus we may wonder if there is a true difference between natural and artificial. The border between these two notions is not as obvious as it seems. The landscapes are shaped by the hand of man, animals are domesticated, and now bacteria are considered as cell factories. A natural reserve is artificially preserved as the result of human actions. Is there still something natural since the birth of humankind? Actually, the artifice is a slight modification of Nature and couldn’t exist by itself. The distinction between natural and artificial seems sterile and we clearly understand that these notions are inextricably linked and need each other to exist. </p><br />
<br />
<p class="texte">In conclusion,isn't it our duty to use our unique position in the history of life and our human approach to try to replace the evolutive processes?</p><br />
<br />
<br />
<p class="title2">Back to our project</p><br />
<br />
<br />
<p class="texte">These inextricable links are obviously the basis of our project. We aim to artificially preserve a natural heritage shaped by Pierre Paul Riquet hundreds years ago. The modification of a naturally occurring form of life to strengthen it is maybe just the imitation of the natural evolution process. What is considered today as ‘non-natural’ may be one day regarded differently. To the extent that everything is done not to unbalance the ecosystem, our intervention can be judged rightful, even more than the use of chemicals.</p><br />
<br />
<br />
<p class="title1" id="select3">SubtiTree</p><br />
<br />
<p class="title2"> Potential strategies discussed<br />
<br> (See more details in the <a href="https://2014.igem.org/Team:Toulouse/Project/Spreading">Spreading</a> dedicated page)<br />
</p><br />
<br />
<p class="texte">To be sure that SubtiTree will not survive and spread in the environment, many strategies were discussed to improve our bacterium: <br />
<br />
<br>- Avoid the survival in the environment thanks to a proline auxotrophy system<br />
<br>- Prevent the sporulation of <I> B. subtilis</I> to make it annual <br />
<br>- Avoid gene transfers between SubtiTree and a wild type bacterium thanks to a toxin-antitoxin system <br />
<br>- Use integrative plasmid to improve the genetic stability<br />
</p><br />
<br />
<br />
<br />
<p class="title2">Public perception<br />
</p><br />
<br />
<p class="texte"><I><CENTER>Political and public adhesion</I></CENTER></p><br />
<br />
<p class="texte">Because of the magnitude of our project,its application interested several civil services. Indeed some municipalities and regional councils supported our local engagement. Beyond that, our project interests the highest level of the “Canal du Midi” administration: the national navigation authority and the Ministry of agriculture funded this project. They are still looking for the best way to further this work after the iGEM competition. </p><br />
<br />
<p class="texte">This project also received the attention of the public through several articles in newspapers, television, radio and internet. First we had just a local coverage, but days after days there were more and more media intereseted in SubtiTree. This mediatic coverage allowed us to contact concerned citizens who participated to the development of this project. This interaction with the public allowed us to explain and promote public knowledge of synthetic biology. </p><br />
<br />
<br />
<p class="texte"><I><CENTER>Safety principle</I></CENTER></p><br />
<br />
<p class="texte">One single tree infected by Canker, and all the trees located in an area of a couple of hundred meters around are included in the prophylactic cut. We acted to preserve the surrounding trees. The modification of the endophytic microbial fauna generated by the introduction of the engineered bacterium has to be compared to the introduction of chemicals. They contain chlorine atom and aromatic hydrocarbon, so their remediation is complicated and they represent a source of pollution. By shortening the lifespan to one season and minimizing the risks of spreading, we plan a safe and environmental-friendly way to fight Canker. <br />
<br />
<br />
<p class="title2">Feasability<br />
</p><br />
<br />
<p class="texte">We wonder about the feasibility of tree’s treatment. As we used endophytic bacteria, we can count on the natural growth of SubtiTree inside the sap. So we can inject few bacteria to be sure to have enough bacteria to protect the tree. Some researchers (Xianling Ji1 et al) already injected <i>Bacillus subtilis</i> in plants and observe an increase of bacteria concentration to a maximum of 10^5 bacteria/mL/p><br />
<br />
<p class="texte">As we aim to inject a poor quantity of bacteria, this treatment remains cheaper than the injection of several litter of fungicides. In addition, this injection prevents the preventive tree cutting, which is very expensive. Cutting one tree cost around €3000. The administration in charge of the protection of the “Canal du Midi” already plans to spend 220 million euros to cut and replant all trees along the Canal. Besides the important cost of cutting trees, it will destroy one of the symbols of south-western France. </p><br />
<br />
<p class="texte">We know that SubtiTree could be improved in many ways, but in the iGEM’s circumstances we could not have the time to go deeper. First, we can improve the fixation module. Using chitin as fixation anchor is simple but not enough specific to fix just one fungus type. That’s why we first think to fix SubtiTree to one protein included in the <I>Ceratocystis platani</I>’s membrane: CP. The bacterial prototype designed this summer can be optimized to trigger the fungicides production when the binding is completed, and to be more specific changing the peptides produced.</p><br />

<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />

"If you don't think it's safe, it probably isn't"</p><br />
<p class="texte">We have organized our workspace. There is the relaxing room where no microbial material should enter. In this room, we can eat and drink (a fridge, a kettle and a coffeemaker are available) but it is also the room where we have our meetings and where we can work on our computers. There is the lab, where we have to wear protective equipment and respect basic rules.</p><br />
<br />
<p class="title3">Personal protective equipment</p><br />
<p class="texte">As soon as we manipulate in the lab, we have to wear the following personal protective equipment:</p><br />
<table><br />
<tr><td><p class="texte">- A conventional lab coat, closed with long sleeves</p></td><br />

</table><br />
<br />
<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />
<br><br />
Indeed, different machine are used to keep a sterile area.</p><br />
<br />
<p class="title3">Waste</p><br />
<p class="texte">Different trash containers are available in the lab:<br><br />
- One for biological waste (yellow). This waste will be autoclaved.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/f7/Yellow_trash.JPG"><br><br><br />
- One for common waste (green or orange).<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/c/c7/Black_garbage.png"><br><br><br />
- Special waste for chemicals.<br />
<br />
<p class="title3">Devices and Material</p><br />
<p class="texte">We use a lot of different devices, and each one involves a particular risk. Here we described how we use this material safely to reduce risks:</p><br />
<p class="title4">Chemical storage</p><br />
<p class="texte">We have three cupboards dedicated to the different kind of chemical products we use:<br><br />
- Flammable<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/35/Flammable.png"><br><br><br />
- Acids<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/36/Acids.png"><br><br><br />
- Bases<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/74/Bases.png"><br><br><br />
Those cupboards are key-closed.</p><br />
<br />
<p class="title4">Ethidium Bromide</p><br />
<p class="texte">We have a dark room dedicated to the use of EtBr and UV. This room is key-closed and everyone entering into the room must wear gloves, glasses and lab coat. Everything which is in direct contact with something in this room has to stay here.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/75/EtBr_room.JPG"><br><br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/4/45/EtBr_door.JPG"><br><br><br />
Two specific trash cans are dedicated to the gloves or paper and the agarose gels contaminated.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/fe/EtBr_garbage.JPG"><br><br></p><br />
<br />
<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />
<br />
<br />
<br />
<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />
</p><br />

<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />

<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />

<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="title1" id="select4">Team safety</p><br />
<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />
</p><br />

"If you don't think it's safe, it probably isn't"</p><br />
<p class="texte">We have organized our workspace. There is the relaxing room where no microbial material should enter. In this room, we can eat and drink (a fridge, a kettle and a coffeemaker are available) but it is also the room where we have our meetings and where we can work on our computers. There is the lab, where we have to wear protective equipment and respect basic rules.</p><br />
<br />
<p class="title3">Personal protective equipment</p><br />
<p class="texte">As soon as we manipulate in the lab, we have to wear the following personal protective equipment:</p><br />
<table><br />

</table><br />
<br />
<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />
<br><br />
Indeed, different machine are used to keep a sterile area.</p><br />
<br />
<p class="title3">Waste</p><br />
<p class="texte">Different trash containers are available in the lab:<br><br />
- One for biological waste (yellow). This waste will be autoclaved.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/f7/Yellow_trash.JPG"><br><br><br />
- One for common waste (green or orange).<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/c/c7/Black_garbage.png"><br><br><br />
- Special waste for chemicals.<br />
<br />
<p class="title3">Devices and Material</p><br />
<p class="texte">We use a lot of different devices, and each one involves a particular risk. Here we described how we use this material safely to reduce risks:</p><br />
<p class="title4">Chemical storage</p><br />
<p class="texte">We have three cupboards dedicated to the different kind of chemical products we use:<br><br />
- Flammable<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/35/Flammable.png"><br><br><br />
- Acids<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/36/Acids.png"><br><br><br />
- Bases<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/74/Bases.png"><br><br><br />
Those cupboards are key-closed.</p><br />
<br />
<p class="title4">Ethidium Bromide</p><br />
<p class="texte">We have a dark room dedicated to the use of EtBr and UV. This room is key-closed and everyone entering into the room must wear gloves, glasses and lab coat. Everything which is in direct contact with something in this room has to stay here.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/75/EtBr_room.JPG"><br><br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/4/45/EtBr_door.JPG"><br><br><br />
Two specific trash cans are dedicated to the gloves or paper and the agarose gels contaminated.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/fe/EtBr_garbage.JPG"><br><br></p><br />
<br />
<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />
<br />
<br />
<br />
<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />

- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />

There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />

<br />
<p class="title3">Devices and Material</p><br />
<p class="texte">We use a lot of different devices, and each one involves a particular risk. Here we described how we use this material safely to reduce risks:</p><br />
<p class="title4">Chemical storage</p><br />
<p class="texte">We have three cupboards dedicated to the different kind of chemical products we use:<br><br />
- Flammable<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/35/Flammable.png"><br><br><br />
- Acids<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/36/Acids.png"><br><br><br />
- Bases<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/74/Bases.png"><br><br><br />
Those cupboards are key-closed.</p><br />
<br />
<p class="title4">Ethidium Bromide</p><br />
<p class="texte">We have a dark room dedicated to the use of EtBr and UV. This room is key-closed and everyone entering into the room must wear gloves, glasses and lab coat. Everything which is in direct contact with something in this room has to stay here.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/75/EtBr_room.JPG"><br><br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/4/45/EtBr_door.JPG"><br><br><br />
Two specific trash cans are dedicated to the gloves or paper and the agarose gels contaminated.<br><br />

<br />
<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />

<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="title1" id="select4">Team safety</p><br />
<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />
</p><br />

"If you don't think it's safe, it probably isn't"</p><br />
<p class="texte">We have organized our workspace. There is the relaxing room where no microbial material should enter. In this room, we can eat and drink (a fridge, a kettle and a coffeemaker are available) but it is also the room where we have our meetings and where we can work on our computers. There is the lab, where we have to wear protective equipment and respect basic rules.</p><br />
<br />
<p class="title3">Personal protective equipment</p><br />
<p class="texte">As soon as we manipulate in the lab, we have to wear the following personal protective equipment:</p><br />

</table><br />
<br />
<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />
<br><br />
Indeed, different machine are used to keep a sterile area.</p><br />
<br />
<p class="title3">Waste</p><br />
<p class="texte">Different trash containers are available in the lab:<br><br />
- One for biological waste (yellow). This waste will be autoclaved.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/f7/Yellow_trash.JPG"><br><br><br />
- One for common waste (green or orange).<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/c/c7/Black_garbage.png"><br><br><br />
- Special waste for chemicals.<br />
<br />
<p class="title3">Devices and Material</p><br />
<p class="texte">We use a lot of different devices, and each one involves a particular risk. Here we described how we use this material safely to reduce risks:</p><br />
<p class="title4">Chemical storage</p><br />
<p class="texte">We have three cupboards dedicated to the different kind of chemical products we use:<br><br />
- Flammable<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/35/Flammable.png"><br><br><br />
- Acids<br><br />

- Bases<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/74/Bases.png"><br><br><br />
Those cupboards are key-closed.</p><br />
<br />
<p class="title4">Ethidium Bromide</p><br />
<p class="texte">We have a dark room dedicated to the use of EtBr and UV. This room is key-closed and everyone entering into the room must wear gloves, glasses and lab coat. Everything which is in direct contact with something in this room has to stay here.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/75/EtBr_room.JPG"><br><br><br />

<img width="150px" src="https://static.igem.org/mediawiki/2014/f/fe/EtBr_garbage.JPG"><br><br></p><br />
<br />
<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />
<br />
<br />
<br />
<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="title1" id="select4">Team safety</p><br />
<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />

<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />
<br><br />
Indeed, different machine are used to keep a sterile area.</p><br />

<p class="title3">Waste</p><br />
<p class="texte">Different trash containers are available in the lab:<br><br />

<p class="texte">We have a dark room dedicated to the use of EtBr and UV. This room is key-closed and everyone entering into the room must wear gloves, glasses and lab coat. Everything which is in direct contact with something in this room has to stay here.<br><br />

<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />

<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="title1" id="select4">Team safety</p><br />
<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />
</p><br />

"If you don't think it's safe, it probably isn't"</p><br />
<p class="texte">We have organized our workspace. There is the relaxing room where no microbial material should enter. In this room, we can eat and drink (a fridge, a kettle and a coffeemaker are available) but it is also the room where we have our meetings and where we can work on our computers. There is the lab, where we have to wear protective equipment and respect basic rules.</p><br />
<br />
<p class="title3">Personal protective equipment</p><br />
<p class="texte">As soon as we manipulate in the lab, we have to wear the following personal protective equipment:</p><br />
<table><br />

</table><br />
<br />
<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />
<br><br />
Indeed, different machine are used to keep a sterile area.</p><br />
<br />
<p class="title3">Waste</p><br />
<p class="texte">Different trash containers are available in the lab:<br><br />
- One for biological waste (yellow). This waste will be autoclaved.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/f7/Yellow_trash.JPG"><br><br><br />
- One for common waste (green or orange).<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/c/c7/Black_garbage.png"><br><br><br />
- Special waste for chemicals.<br />
<br />
<p class="title3">Devices and Material</p><br />
<p class="texte">We use a lot of different devices, and each one involves a particular risk. Here we described how we use this material safely to reduce risks:</p><br />
<p class="title4">Chemical storage</p><br />
<p class="texte">We have three cupboards dedicated to the different kind of chemical products we use:<br><br />
- Flammable<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/35/Flammable.png"><br><br><br />
- Acids<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/36/Acids.png"><br><br><br />
- Bases<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/74/Bases.png"><br><br><br />
Those cupboards are key-closed.</p><br />
<br />
<p class="title4">Ethidium Bromide</p><br />
<p class="texte">We have a dark room dedicated to the use of EtBr and UV. This room is key-closed and everyone entering into the room must wear gloves, glasses and lab coat. Everything which is in direct contact with something in this room has to stay here.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/75/EtBr_room.JPG"><br><br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/4/45/EtBr_door.JPG"><br><br><br />
Two specific trash cans are dedicated to the gloves or paper and the agarose gels contaminated.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/fe/EtBr_garbage.JPG"><br><br></p><br />
<br />
<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />
<br />
<br />
<br />
<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="title1" id="select4">Team safety</p><br />
<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />
</p><br />

<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />
<br><br />
Indeed, different machine are used to keep a sterile area.</p><br />
<br />
<p class="title3">Waste</p><br />
<p class="texte">Different trash containers are available in the lab:<br><br />
- One for biological waste (yellow). This waste will be autoclaved.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/f7/Yellow_trash.JPG"><br><br><br />
- One for common waste (green or orange).<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/c/c7/Black_garbage.png"><br><br><br />
- Special waste for chemicals.<br />
<br />
<p class="title3">Devices and Material</p><br />
<p class="texte">We use a lot of different devices, and each one involves a particular risk. Here we described how we use this material safely to reduce risks:</p><br />
<p class="title4">Chemical storage</p><br />
<p class="texte">We have three cupboards dedicated to the different kind of chemical products we use:<br><br />
- Flammable<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/35/Flammable.png"><br><br><br />

Those cupboards are key-closed.</p><br />
<br />
<p class="title4">Ethidium Bromide</p><br />
<p class="texte">We have a dark room dedicated to the use of EtBr and UV. This room is key-closed and everyone entering into the room must wear gloves, glasses and lab coat. Everything which is in direct contact with something in this room has to stay here.<br><br />

<br />
<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />

<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />

<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="texte"> We used and developed several protocols to demonstrate the existence of chemotaxis in <i>B. subtilis</i> wild type (WT) strain and SubtiTree bacterium towards N-Acetylglucosamine. <br />
</p><br />
<p class="title2">1. Petri Dishes Test </p><br />
<br />
<p class="texte">We first wanted to visualize chemotaxis on Petri dishes. We hoped to obtain pictures with bacteria halos directed or around attractive components and thus tried different protocols. The first protocol was adapted from the one published by <a href="https://2011.igem.org/Team:Imperial_College_London/Protocols_Chemotaxis">the Imperial College 2011 iGEM team</a>. They put the attractive compound on a paper disk in the middle of a Petri dish containing a medium with 0.3% agar. Cells are loaded in this medium (Figure 1).<br />
</br><br />
</br><br />
<b>We first tried to test chemotaxis onto Petri Dishes filled with a 0.3% agar medium. This semi-solid medium allows the bacterial motility. A paper disk containing an attractive compound is placed in the middle of the dish and cells are then loaded in the medium (see Figure 1). This protocol was taken from the <a href="https://2011.igem.org/Team:Imperial_College_London/Protocols_Chemotaxis">the Imperial College 2011 iGEM team</a></b>.</p><br />

<p class="legend">Figure 1: Scheme showing how cells are filled into the medium. (A) A pipet tip is used to deposit cells in the gelose. (B) Bacteria should move toward the attractive compound which diffuses.</p><br />
<br />
<p class="texte">We did not have any result with WT <i>Bacillus subtilis</i> and glucose as attractive compound (Figure 2-A). <i>B. subtilis</i> is attracted by many other glucides and amino-acids, so we also tried to test diluted glucose in LB medium attractant (Figure 2-B).</p><br />
<br />

<p class="legend">Figure 2: Chemotaxis test with Glucose as attractive compound (A) and Glucose added to LB medium as attractant (B).</p><br />
<br />
<p class="texte"> We could not notice any difference between the petri dish with or without glucose. With an addition of LB medium to sugar, a large halo around the paper disk was noticeable. This halo may correspond to cells attracted by the solution, as it is not noticeable when cells are not added (data not shown). Anyway we did not have enough reproducible and reliable results to be satisfied with this test.<br> <br />
Furthermore, with the addition of LB medium, it is hard to make the distinction between the attractive effects and the simple growth resulting from random diffusion.</br><br />
We have started new tries using different protocols.</p><br />
<br />
<p class="title2">2. Plug in Pond system<br />
</p><br />
<br />
<p class="texte"><br />
This protocol we worked on is taken from a thesis (see references [1]). . A solution of <i>B.subtilis</i> is grown overnight so as to obtain a cell density of 8x10⁸ cells/mL. 10mL of the solution is mixed with 15mL of LB medium with 1.5 % agar kept at 45°.The final concentration of the obtained medium is 0.9% agar. Tetracycline is aded at 25µg/mL, in order to inhibit growth and to only observe the chemotaxis phenomenon. Plates are cooled and dried, before digging wells with a punch or 1mL tips. The wells are filled with attractive compounds (Figure 3). After one hour at room temperature, photos of the plates are taken and the results are analyzed.<br />
</p><br />
<br />
<center><img SRC="https://static.igem.org/mediawiki/2014/c/cd/Fig3.png" alt="Figure 3" style="width:400px"></center><br />
<p class="legend">Figure 3: Schema showing how are made plug-in-pond tests.</p><br />
<br />
<p class="texte"><br />
On our first try with <i>B. subtilis</i>, we made three wells per plate (Figure 4).The wells were filled with glucose at different concentrations and tetracycline was not added in one of the plates.<br />
</p><br />
<br />
<center><img SRC="https://static.igem.org/mediawiki/2014/c/ce/Fig4.png" alt="Figure 4" style="width:400px"></center><br />
<p class="legend">Figure 4: Plates after 12h at room temperature.</p><br />
<br />
<p class="texte"><br />
After an hour, no tangible results were obtained. It is only after 12hours that we were able to observe halos around the wells with glucose at 1M in the plates without tetracycline. Tetracycline concentration seems to be too high and inhibits any bacterial activity. Therfore, we have worked with tetracycline at 15µg/mL.<br />
We tried this protocol again with this new condition. We made two wells per plate (Figure 5), one with either Glucose or N-acetyl-glucosamine and one with LB medium. As previsously, no results were achieved after 1h, but after 12hours we could notice halos.<br />
</p><br />
<br />

<p class="legend">Figure 5: Chemotaxis test with <i>Bacillus subtilis</i> WT. The upper wells contain attractive compound and the lower contain medium without attractive compound. </p><br />
<br />
<p class="texte"><br />
Results are not as clear as the first time, but we observed halos around the well with glucose at 250mM with and without tetracycline. We have then tried the same experiment with N-acetyl-glucosamine and we did not see any halo in the tested conditions. Thus we assumed that our <i>B. subtilis</i> 168 strain was not attracted to N-acetyl-glucosamine.<br />
However, the results are not clear, reliable and reproducible enough with the plug-in-pond protocol. Another testing protocol was then adopted. <br />

<p class="title2">4. Capillary test between two tubes also called the tubes test</p><br />
<p class="texte">After the experiment of the plug-in-pond, we decided to construct a system by welding two Eppendorf tubes with a capillary thanks to an electric burner.</p><br />

<br />
<p class="texte">We tested this system with a fuchsin dye and water and we were able to observe the diffusion of fuchsin towards water. However this construction had a leakage next to the weld seam that we could not stop. <br />
Thus, we asked the help from the INSA glass blower, Patrick Chekroun. He designed two systems composed of two tubes linked by a capillary.</p><br />
<br />

<p class="legend">Figure 7: Scheme of the tubes system</p><br />
<br />
<p class="texte">As we did previously, we tested this new system with fuchsin. This experiment was made with WT <i>Bacillus subtilis</i> and N-Acetylglucosamine.<br />
<br><br><br />
<i>NB: We could not see the diffusion from one tube to the other. We made the hypothesis that it was not visible by sight because of the small diameter of the capillary. <br />
</i><br><br />
<br><br />
The following strategy was used to avoid disturbance due to pressure and liquid movement through the capillary:<br><br />
- The first step was the addition of Wash Buffer until the capillary was full to avoid the presence of air bubbles which could lead to diffusion problems.<br><br />
- Then, the tube 2 was plugged with the thumb while another person was adding the bacterial solution of WT <i>Bacillus subtilis</i> in the tube 1. <br><br />
- The tube 1 was also plugged and only after the thumb could be removed from the tube 2. <br><br />
- In the same way, the N-Acetylglucosamine was added in the tube 2. <br><br />
- The same process was made with a xylose positive control.<br><br />
<br><br />
<i>NB: According to the article Chemotaxis towards sugars by </i>Bacillus subtilis, (George W. Ordal et al., 1979), <i>glucose and xylose have the same attractant power. We prefer a positive control instead of a negative one because we were not sure that this system was efficient.</i><br><br />
<br><br />
- The system was kept straight for 2hours. Every 40 minutes, we took a sample of each tube and spread it on an agar plate (dilution 1/1,000).</p><br />

<p class="legend">Figure 8: Photography of the tubes system</p><br />
<br />
<br />
<p class="texte">Unfortunately, the dilution was too high to detect any chemotaxis movement and the time was too short. We did not find any information in the literature.<br><br />
As we did not have the time to optimize this protocol we preferred using the protocol of the 2011 Imperial college iGEM team : the tips capillary test.</br><br />
</p><br />
<br />
<p class="title2"> 5. Tips capillary system</p><br />
<p class="title3">First tips capillary system</p><br />
<p class="texte">This protocol comes from 2011 Imperial College iGEM team and was adapted by our team in several steps (See <a href="https://2014.igem.org/Team:Toulouse/Notebook/Protocols#select8">chemotaxis protocol</a>).<br />
<br><br />
In the first tips capillary system, we used parafilm to avoid any kind of air disturbance in the tips. The different steps are described below:<br><br />
- 15µL of each chemo-attractant was pipetted. <br><br />
- The bottom of tip with the pipette was then put on a piece of parafilm and the pipette was removed from the top of the tip.<br><br />
- The top of the tip was then sealed with a piece of parafilm. By this way, the sterility can be assured and the liquid stays inside the tip. <br><br />
- To finish, the level of the solution in the tip was marked.<br></p><br />
<br />

<p class="legend">Figure 9: Sealing of a tip with parafilm</p><br />
<br />
<p class="texte">- After all the attractants were added in the tips, we put them on a green base to carry them. The whole process can be seen on Figure 10.<br><br />
- Each tip was immersed in 300 µL of a bacterial solution in the wells of an Elisa plate.<br></p><br />

<p class="legend">Figure 10: First tips capillary system</p><br />
<br />
<p class="texte"><i>NB: the yellow carton was used to stabilize the system and keep it straight.</i><br><br />
<br><br />
- After one hour, the tips were removed from the bacteria solutions and the content of the tips was observed with a Thoma cell under the microscope.<br><br />
<br><br />
We had several problems with this system:<br><br />
- The liquid level decreased during the experiment and we did not have enough liquid to fill the Thoma cell. Thus, it was not possible to count.<br><br />
- The bacteria were moving and therefore, we could not proceed to a bacteria count.<br><br />
<br><br />
Regarding these observations we decided to spread the tips content on agar plates instead of using Thoma cell and microscopy.<br><br />
<p class="title3">Second tips capillary system<br />
</p><br />
<p class="texte"And then the revolution came! We found a multichannel pipette :D The same protocol was performed except that the parafilm was used to avoid the air entrance between the tips and the pipette and therefore the loss of liquid.<br></p><br />

<br />
<p class="texte"><b>At that point, the protocol was approved and the final test could finally start! :-)</b><br><br />
<br><br />
There was just one tiny problem… we did not have our optimized bacterium transformed with the chemotaxis module!!! That is why we concentrated our efforts on WT <i>Bacillus subtilis</i> strain.<br><br />
<br><br />
The main goal was to find an optimized control and to analyze the eventual chemotaxis of the WT strain. To avoid osmolality bias, we wanted to find a molecule which was non-attractant and with a similar molecular weight than the N-Acetylglucosamine (221.21 g/mol). Our first idea was to use fuchsin (Molecular weight: 337.85 g/mol).<br><br />
<br><br />
At the beginning, the experiment was conducted with only one negative contraol, the fuchsin and different NAG concentrations: 25mM, 250mM and 500mM. The tested strain was <i>Bacillus subtilis </i>168:<br><br />
<br></p><br />

<td align=center><p class="legend">Figure 14: NAG (25mM) (dilution 1/50)</p></td></tr><br />
</table></center><br><br />
<p class="texte">The average number of colonies with the negative control is 121. On the contrary, a cell layer is observed for the NAG plates with every concentration.<br><br />
<br><br />
Thus, we assumed that WT <i>Bacillus subtilis</i> was more attracted by NAG than fuchsin. Indeed we can neglect the bacterial growth because the test only lasts one hour. We also neglect diffusion and osmolality phenomena for the previous reasons. <br><br />
<br><br />
Unfortunately for us we forgot one major effect… Can you believe that fuchsin solution contains about 15% of ethanol?!!! This concentration can lead to the death of some cells which probably happened to our results.<br><br />
<br><br />
<b><p class="texte">This incredible and dramatic discovery destroyed all of our hopes about the God of chemotaxis! :-(</b><br><br />
<br><br />
However, our team did not give up on synthetic biology ! :-) Indeed, after days of disappointment and no time left for lab work, we raised from ashes and tried to find another negative control.<br><br />
<br><br />
Hopefully, we managed to find a negative control: galactose (25mM). The article Chemotaxis towards sugars by <i>Bacillus subtilis</i> (<i>George W. Ordal et al., 1979</i>) proved that it was a poor attractant.<br><br />
<br><br />
We made our tests again with this new molecule and glucose (25mM) as positive control.<br></p><br />

<p class="texte"> The miracle arrived! We managed to prove that our WT <i>Bacillus subtilis</i> was indeed naturally attracted to NAG.</p><br />
<p class="texte"><i>NB: It was our last experiment. Unfortunately we were running out of time and we could not do much more test. We would like to do the experiment with a lower dilution and repeat it several times.</i><br><br />

<p class="title2">1. Preliminary experiments</p><br />
<p class="title3">Purpose</p><br />
<p class="texte">The first experiment deals with the culture conditions to see if <i>Bacillus subtilis</i> can resist to a low temperature and with the Chitin Beads Buffer (CBB) buffer. To do that, several bacterial concentrations have been tested starting with an OD of 0.1 and diluting this solution to get estimated ODs of 0.05, 0.025, 0.01. These different <i>Bacillus subtilis</i> solutions were incubated 1 hour at 4°C with 500µL of CBB or water. Finally a cell count on Thoma cell counting chamber was performed.</p><br />
<br />
<p class="title3">Results</p><br />
<p class="texte">We could not count bacteria either because of the high number of bacteria with the 0.1 OD solution or the low number of bacteria with the 0.01 OD solution. Thus, the study is mostly focused on the intermediate values (Figure 16).<br />
<br/>First of all, cells do not seem affected by the presence of CBB or water with estimated ODs of 0.05 or 0.025. Moreover, twice less cells can be found in the lowest concentrations in bacteria comparing to the 0.05 OD concentration which is in agreement with the dilution ratio.<br />
</br>Thus the the experimental conditions regarding the presence of CBB and the incubation temperature at 4°C are compatible with the bacterial life. <br />
<br/>Thus, the experimental conditions regarding the presence of CBB and the incubation temperature at 4°C do not harm the cell surviving.<br />

<br />
<p class="title2">2. Binding test using engineered <i>B. subtilis</i></p><br />
<br />
<p class="title3">Purpose</p><br />
<p class="texte"><i>B. subtilis</i> transformed with the binding module should produce a chimeric protein composed of the Cell Wall Binding Domain of LycT to attach the chimeric protein to the cell wall, and the GbpA domain 4 of <i>Vibrio cholerae</i> to bind chitin. The synthetic bacterium is put in contact with chitin beads (chitin: polymer present on the fungal pathogen wall). After several washes, bacteria remaining on the beads are counted.</p><br />
<br />
<p class="title3">Results</p><br />
<p class="texte">The first observation is that both bacterial solutions of wild type <i>Bacillus subtilis</i> and SubtiTree have the same concentration: 10^5 bacteria/mL (Figure 17). Even though there is no significant difference between both strains after the first wash, the second wash has a major effect since it removes 40 times more wild-type bacteria than SubtiTree. This result correlates to the number of Subtitree bound to the beads. <br />
<br/>Thus, the binding system is validated: SubtiTree binds efficiently to chitin.</p><br />
<br />

The <span style="color:#0000FF">WT bacteria</span> or <span style="color:#FF0000">the bacteria with the binding system</span> concentrations have been determined during the different steps of the binding test. The stars represent a significant difference observed with a Student test with p<0.05.<br />
</p><br />
<br />
<p class="title2">3. Microscopic observations</p><br />
<br />
<p class="title3">Purpose</p><br />
<p class="texte">We wanted to observe SubtiTree bound on the chitin coated beads. In order to perform a 3D reconstruction showing this interaction, we used confocal laser scanning microscope. Through the use of a fluorochrome (Syto9), we highlighted the presence of bacteria on the surface of the beads (individualized by phase-contrast). A first calibration step determined the minimum threshold to remove the background noise and the natural fluorescence.</p><br />
<br />
<p class="title3">Results</p><br />
<p class="texte">First, we can notice that SubtiTree is sitting (well, sort off!!) on the surface of beads coated with chitin. These images seem to highlight their interactions.</br></p><br />

<p class="legend">Figure 19: A short movie of 3D bead surfaces coated with chitin and Subtitree (emotional sequence for Subtitree: first movie apparition, before Cannes…)</p><br />
<br />
<p class="texte">We then performed a wash step on the chitin beads. We measured the release of bacteria on the washing solution. When our bacterium has the binding module, there is less release and therefore, SubtiTree is retained by the beads.</p><br />

<br />
<p class="texte">Finally, all results are consistent with the presence of functional binding system. We thus validate the second module.</p><br />

<br />
<p class="title2"> 1. Preliminary experiments</p><br />
<p class="title3">Tests with commercial peptides and controls</p><br />
<p class="texte">The first tests were accomplished with commercial GAFP-1 and D4E1 peptides at different concentrations (12.5µM, 25µM, 100µM). These tests were performed on different fungal strains sharing the same phylum with <i>Ceratocystis Platani</i>.<br />
As <i>Ceratocystis Platani</i> is pathogenic, we could not perform tests directly with this fungus.</br><br />
After several days at 30°C, the PDA (Potato Dextrose Agar) plates covered with fungus and commercial peptides were analyzed.</p></p><br />
<p class="texte">An inhibition halo was noticeable with commercial D4E1 peptide at 100µM on <i>Aspergillus brasiliensis</i>. Less bright halos were also present with lower concentrations. Concerning commercial GAFP-1, we did not notice any effect in the tested conditions. As positive control, a well-known chemical fungicide was used: the Copper Sulfate. The inhibition of the fungal growth was complete at 20mg/ml, and at 10mg/ml a darker halo appeared around the pad filled with Copper Sulfate as we can see on the figure below. This corresponds to a sporulating halo in response to the stress generated by the fungicide.<br />

<p class="legend"> Figure 21: Results of the preliminary tests</p><br />
<br />
<br />
</br><br />
<br />
<p class="texte">Regarding these results, we concluded that very high fungicide concentrations are required to inhibit the fungal growth. Following these tests, new conditions were adopted in order not to encourage too much fungal growth over bacterial growth. The culture medium was adjusted to fit our objective and to approximate the conditions found in the trees: a 'sap-like' medium was elaborated. The incubations were then carried at room temperature.<br />
</p><br />
<br />
<p class="title2">2. Test with SubtiTree</p><br />
<br />
<p class="texte">In order to test <i>Bacillus subtilis</i> mutants, it was essential to find the right balance between the fungal growth and the bacterial one. This condition was necessary to get a high concentration of peptides. In our genetic constructions, these peptides are designed to be exported in the extracellular medium.</br><br />
</br><br />
The transformed <i>Bacillus subtilis</i> strains grew at 37°C during 72h and were tested. After centrifugation, the supernatant and the resuspended pellet were placed on pads and disposed on plates previously seeded with a defined number of conidia (see protocols to have more details). After several days at room temperature, an inhibition halo of <i>Trichoderma reesei</i>'s growth was clearly observable for the strain expressing D4E1 gene. The inhibition was even more noticeable with the strain carrying the GAFP-1 + D4E1 operon (see the photos below).</br><br />
However, no effect was detected for the strain expressing the GAFP-1 gene, supposing a synergistic effect between these two peptides.</br><br />
Regarding EcAMP and the triple-fungicides operon, no effect has been detected on the fungal growth. Several factors can explain these results: a number of post-transcriptional modifications are required to have a functional EcAMP and in addition to that, sequencing results of these constructs showed some differences with the original designed sequence.<br />
<p class="texte">Inhibition halos are not visible with supernatants, probably because of their low concentrations in the extracellular medium. <br />
Another effect was noted with the same strains expressing D4E1 and GAFP-1 + D4E1 on another fungus <i>Aspergillus brasiliansis</i>. This effect is comparable to the one previously noted with a low concentration of sulfate copper. </br><br />

<p class="texte"><br />
The choice of our chassis appears to be optimal as we noted that wild type <i>Bacillus subtilis</i> disturbs the hyphae growth of the fungi. Some strains of <i>Bacillus subtilis</i> (qst 713) are already used as Biofungicides for use on several minor crops to treat a variety of plant diseases and fungal pathogens.</br><br />
After this set of experiments, the strains expressing D4E1 and expressing GAFP-1 + D4E1 have shown to be the best candidates to play a major role in the fight against fungal diseases such as Canker stain. Keeping in mind our objective, <b> we decided to tests these strains in model plants</b>: <i>Nicotiana benthamiana</i> and <i>Arabidopsis thaliana</i>.</br><br />
These tests were performed in the National Institute for the Agronomic Research by experts in this domain. <br />
<br />

<p class="title2">3. <i>In planta</i> tests with SubtiTree</p><br />

<p class="legend"> Figure 23: Injection of SubtiTree in a model plant</p><br />
<br />
<p class="texte"><br />
The goal of the project is to introduce the transformed bacteria in a diseased tree. So it is necessary to perform <i> in planta </i> tests to judge the fungus-killing abilities of the two strains selected after the previous set of experiments. </br><br />
SubtiTree is first inoculated in two model plants (<i>Arabidopsis thaliana</i> and <i>Nicotiana benthamiana</i>). After this step, a phytopathogenic fungus (<i>Sclerotinia sclerotiorum</i>) is placed on the leaves. </br><br />
These tests were made in association with Sylvain Raffaële and Marielle Barascud of the National Institute for the Agronomic Research laboratory. </br><br />
</p><br />
<br />
<br />
<br />
<p class="texte">Twenty-four hours after SubtiTree inoculation, no phenotypic modification of the leaves can be detected. We can conclude that our bacterium, its introduction and the fungicides production in plants do not have deleterious effects.</br><br />
Without proper treatment, the drop of the pyhtopathogenic fungus on <i>Nicotiana benthamiana</i>'s leaves causes a necrosis halo which can be measured after 40h. The lesion size and the number of inoculated sites seem to be reduced by <i>B. subtilis</i> expressing DE41 or GAFP1-D4E1, unlike with the WT bacterium. A second set of experiments is expected to be more statistically precise.</br><br></br><br />
We did not observe any significant results for <i>Arabidopsis thaliana</i> because of the use of two plants batches with different ages.</br><br />
<br />
We can therefore conclude that when SubtiTree is in plant's physiological conditions, <b> it is harmless to the plant, and that the production of fungicides is effective, reducing the leaves necrosis. </b><br />

<p class="title1" id="select4">Team safety</p><br />
<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />

<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />
<br><br />
Indeed, different machine are used to keep a sterile area.</p><br />
<br />
<p class="title3">Waste</p><br />
<p class="texte">Different trash containers are available in the lab:<br><br />
- One for biological waste (yellow). This waste will be autoclaved.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/f7/Yellow_trash.JPG"><br><br><br />
- One for common waste (green or orange).<br><br />

- Special waste for chemicals.<br />
<br />
<p class="title3">Devices and Material</p><br />
<p class="texte">We use a lot of different devices, and each one involves a particular risk. Here we described how we use this material safely to reduce risks:</p><br />
<p class="title4">Chemical storage</p><br />
<p class="texte">We have three cupboards dedicated to the different kind of chemical products we use:<br><br />
- Flammable<br><br />

<br />
<p class="title4">Ethidium Bromide</p><br />
<p class="texte">We have a dark room dedicated to the use of EtBr and UV. This room is key-closed and everyone entering into the room must wear gloves, glasses and lab coat. Everything which is in direct contact with something in this room has to stay here.<br><br />

<br />
<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />

<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />
</p><br />

"If you don't think it's safe, it probably isn't"</p><br />
<p class="texte">We have organized our workspace. There is the relaxing room where no microbial material should enter. In this room, we can eat and drink (a fridge, a kettle and a coffeemaker are available) but it is also the room where we have our meetings and where we can work on our computers. There is the lab, where we have to wear protective equipment and respect basic rules.</p><br />
<br />
<p class="title3">Personal protective equipment</p><br />
<p class="texte">As soon as we manipulate in the lab, we have to wear the following personal protective equipment:</p><br />
<table><br />

</table><br />
<br />
<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />
<br><br />
Indeed, different machine are used to keep a sterile area.</p><br />
<br />
<p class="title3">Waste</p><br />
<p class="texte">Different trash containers are available in the lab:<br><br />
- One for biological waste (yellow). This waste will be autoclaved.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/f7/Yellow_trash.JPG"><br><br><br />
- One for common waste (green or orange).<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/c/c7/Black_garbage.png"><br><br><br />
- Special waste for chemicals.<br />
<br />
<p class="title3">Devices and Material</p><br />
<p class="texte">We use a lot of different devices, and each one involves a particular risk. Here we described how we use this material safely to reduce risks:</p><br />
<p class="title4">Chemical storage</p><br />
<p class="texte">We have three cupboards dedicated to the different kind of chemical products we use:<br><br />
- Flammable<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/35/Flammable.png"><br><br><br />
- Acids<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/36/Acids.png"><br><br><br />
- Bases<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/74/Bases.png"><br><br><br />
Those cupboards are key-closed.</p><br />
<br />
<p class="title4">Ethidium Bromide</p><br />
<p class="texte">We have a dark room dedicated to the use of EtBr and UV. This room is key-closed and everyone entering into the room must wear gloves, glasses and lab coat. Everything which is in direct contact with something in this room has to stay here.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/75/EtBr_room.JPG"><br><br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/4/45/EtBr_door.JPG"><br><br><br />
Two specific trash cans are dedicated to the gloves or paper and the agarose gels contaminated.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/fe/EtBr_garbage.JPG"><br><br></p><br />
<br />
<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />
<br />
<br />
<br />
<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />

"If you don't think it's safe, it probably isn't"</p><br />
<p class="texte">We have organized our workspace. There is the relaxing room where no microbial material should enter. In this room, we can eat and drink (a fridge, a kettle and a coffeemaker are available) but it is also the room where we have our meetings and where we can work on our computers. There is the lab, where we have to wear protective equipment and respect basic rules.</p><br />
<br />
<p class="title3">Personal protective equipment</p><br />
<p class="texte">As soon as we manipulate in the lab, we have to wear the following personal protective equipment:</p><br />

<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />
<br><br />
Indeed, different machine are used to keep a sterile area.</p><br />
<br />
<p class="title3">Waste</p><br />
<p class="texte">Different trash containers are available in the lab:<br><br />
- One for biological waste (yellow). This waste will be autoclaved.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/f7/Yellow_trash.JPG"><br><br><br />
- One for common waste (green or orange).<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/c/c7/Black_garbage.png"><br><br><br />
- Special waste for chemicals.<br />
<br />
<p class="title3">Devices and Material</p><br />
<p class="texte">We use a lot of different devices, and each one involves a particular risk. Here we described how we use this material safely to reduce risks:</p><br />
<p class="title4">Chemical storage</p><br />
<p class="texte">We have three cupboards dedicated to the different kind of chemical products we use:<br><br />
- Flammable<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/35/Flammable.png"><br><br><br />

Those cupboards are key-closed.</p><br />
<br />
<p class="title4">Ethidium Bromide</p><br />
<p class="texte">We have a dark room dedicated to the use of EtBr and UV. This room is key-closed and everyone entering into the room must wear gloves, glasses and lab coat. Everything which is in direct contact with something in this room has to stay here.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/75/EtBr_room.JPG"><br><br><br />

<br />
<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />

- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="title1" id="select4">Team safety</p><br />
<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />
</p><br />

"If you don't think it's safe, it probably isn't"</p><br />
<p class="texte">We have organized our workspace. There is the relaxing room where no microbial material should enter. In this room, we can eat and drink (a fridge, a kettle and a coffeemaker are available) but it is also the room where we have our meetings and where we can work on our computers. There is the lab, where we have to wear protective equipment and respect basic rules.</p><br />
<br />
<p class="title3">Personal protective equipment</p><br />
<p class="texte">As soon as we manipulate in the lab, we have to wear the following personal protective equipment:</p><br />
<table><br />

</table><br />
<br />
<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />
<br><br />
Indeed, different machine are used to keep a sterile area.</p><br />
<br />
<p class="title3">Waste</p><br />
<p class="texte">Different trash containers are available in the lab:<br><br />
- One for biological waste (yellow). This waste will be autoclaved.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/f7/Yellow_trash.JPG"><br><br><br />
- One for common waste (green or orange).<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/c/c7/Black_garbage.png"><br><br><br />
- Special waste for chemicals.<br />
<br />
<p class="title3">Devices and Material</p><br />
<p class="texte">We use a lot of different devices, and each one involves a particular risk. Here we described how we use this material safely to reduce risks:</p><br />
<p class="title4">Chemical storage</p><br />
<p class="texte">We have three cupboards dedicated to the different kind of chemical products we use:<br><br />
- Flammable<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/35/Flammable.png"><br><br><br />
- Acids<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/36/Acids.png"><br><br><br />
- Bases<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/74/Bases.png"><br><br><br />
Those cupboards are key-closed.</p><br />
<br />
<p class="title4">Ethidium Bromide</p><br />
<p class="texte">We have a dark room dedicated to the use of EtBr and UV. This room is key-closed and everyone entering into the room must wear gloves, glasses and lab coat. Everything which is in direct contact with something in this room has to stay here.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/75/EtBr_room.JPG"><br><br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/4/45/EtBr_door.JPG"><br><br><br />
Two specific trash cans are dedicated to the gloves or paper and the agarose gels contaminated.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/fe/EtBr_garbage.JPG"><br><br></p><br />
<br />
<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />
<br />
<br />
<br />
<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />

In this room, we can eat and drink (a fridge, a kettle and a coffeemaker are available) but it is also the room where we have our meetings and where we can work on our computers. There is the lab, where we have to wear protective equipment and respect basic rules.</p><br />

<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />

<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />

<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="texte">Our engineered bacterium is designed to be inoculated in a tree and to cure fungal diseases. To target the possible environmental issues resulting of using a modified organism directly on trees bordering the Canal du Midi, our team worked on different aspects to ensure a safe use of SubtiTree. <br />
The first objective is to avoid the spreading of our smart bacterium outside the tree. In other words, the purpose is to ensure that once SubtiTree is in the tree, it is unable to live anywhere else. Another issue concerns the horizontal transfers of the genetic material between different bacteria. <br />
Taking into account these issues, we imagined three modules.<br />
</p><br />

<center style="margin-bottom:80px;"><img alt="schema" style="width:700px; z-index:2; " src="https://static.igem.org/mediawiki/2014/2/27/Spreading_sch%C3%A9ma.jpg"></img></center><br />

<a class="NSporing" HREF="#NonSporing"></a><br />
<a class="Tox" HREF="#Toxin"></a><br />
</div><br />
<br />
<p class="title1">Survival in the environment: proline auxotroph <i>B. subtilis</i></p><br />
<p class="texte">SubtiTree will live in sap tree, thus we will use an endophyte <I>B. subtilis</I> strain. In order to contain our bacteria in this area during a short period of time, we thought of modifying some of its survival characteristics. To make the bacterium growth dependant on the presence of the tree (and therefore avoid spreading in the environment), we planned to use a <i>B.subtilis</i> strain auxotroph for proline. The bacterium should then be unable to synthesize this essential amino acid. Proline is the most abundant amino acid in the phloem sap. If the bacterium is in the sap, it should grow normally without any deficiency, but if it escapes from the tree and <i>a fortiori</i> from the sap, it will not be able to survive for a long time (proline is present only in very low quantities in the ground). <br />
<br/> <br />
Auxotroph <i>B.sutbilis</i> strains already exist and are indexed in databases as BGSC (Bacillus Genetic Stock Center), therefore they should be easy to find.</p><br />
<br />
<p class="title1">Preventing sporulation of <i>B. subtilis</i></p><br />
<p class="texte"><br />
It is known that endophyte bacteria must sporulate to survive to winter. In order to limit the spreading of our bacterium, we planned to limit its lifespan to only one season. The bacteria should be injected in spring, grow during the summer and finally should die in the fall.<br\> <br />
<i>B. subtilis</i> is a sporing bacterium: sporulation enables the microorganism to resist very harsh conditions and to spread from tree to tree.<br/> <br />
To control any unwanted long-term development of SubtiTree, our strain should therefore be deficient for sporulating. We USED or COULD USE a <I>B.subtilis</I> strain deficient in the late genes for sporulation. Thus, during fall, when the sap become less nutritious and the temperature is low, the engineered bacterium will die and not pass through the following winter.<br/><br />
In addition, deleting all the engineered bacterial community every year puts a brake on the evolution due to random mutation, thus allowing a better faith on the genetic constructions.<br />
</p><br />
<br />
<p class="texte">These two first characteristics of SubtiTree demonstrate that it should be an annual bacterium, growing only in sap tree. By combining them, they should prevent any long term colonization of any other ecological niche than the plane trees</p><br />
<br />
<br />
<p class="title1">Gene transfer: toxin-antitoxin system</p><br />
<br />
<p class="texte">We also wondered about horizontal genes transfer. The goal of this module is to prevent horizontal transfers between bacteria and any exchange of synthetic genetic material that could be dangerous between wild type organisms and optimized organisms.<br />
<br>We thought about a system limiting such transfers: a toxin-antitoxin module. It involves the addition of two genes to the bacterium: a gene encoding for a toxin (for example <i>tse2</i>) and a gene encoding for the antitoxin (<i>tsi1</i>), placing them in an opposite way on the genome. The large space between them prevents simultaneous transfers: if the optimized bacterium transfers the gene encoding for the toxin, the probability that the gene encoding for the antitoxin may be transferred simultaneously is really low since they are located far away from each other.<br/><br />
Therefore, if anther host bacterium receives the gene encoding for the toxin, it will be unable to survive since it will not possess the antitoxin. If it receives the antitoxin only, it will not be useful for the bacterium, and will not affect it.<br/><br />
In summary, since a simultaneous transfer is dimly probable, the bacterium will either die because of the toxin or live while expressing the antitoxin. <br />
</p><br />
<br />
<p class="texte">Our synthetic genes are not the only problem in the design of SubtiTree. One of the side effects of our cloning method is the persistence of antibiotic resistance genes. This is incompatible with the introduction of SubtiTree in the environment. It is possible to delete this resistance in chromosome.<br />
<br><br />
While we have not constructed yet these modules, we definitely think that the measures that we designed should render the use of SubtiTree acceptable in the environment. <br />
</p><br />
<br />
<p class="title1">Using integrative plasmids</p><br />
<p class="texte"><br />
All our constructions are carried by integrative plasmids. Consequently, our different genetic modules should be integrated into the bacterium genome. The integration in the genome is more stable as the constructions are less likely to be transferred to other microorganisms. In addition to that, the expression of our genetic modules would not be dependent on a selective pressure, allowing a high level of transcription <i>in planta</i>. <br />

<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />

<p class="texte">We have organized our workspace. There is the relaxing room where no microbial material should enter. In this room, we can eat and drink (a fridge, a kettle and a coffeemaker are available) but it is also the room where we have our meetings and where we can work on our computers. There is the lab, where we have to wear protective equipment and respect basic rules.</p><br />

<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />
<br><br />
Indeed, different machine are used to keep a sterile area.</p><br />

<p class="title3">Waste</p><br />
<p class="texte">Different trash containers are available in the lab:<br><br />

<p class="title4">Ethidium Bromide</p><br />
<p class="texte">We have a dark room dedicated to the use of EtBr and UV. This room is key-closed and everyone entering into the room must wear gloves, glasses and lab coat. Everything which is in direct contact with something in this room has to stay here.<br><br />

<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />

<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="title1" id="select4">Team safety</p><br />
<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />
</p><br />

"If you don't think it's safe, it probably isn't"</p><br />
<p class="texte">We have organized our workspace. There is the relaxing room where no microbial material should enter. In this room, we can eat and drink (a fridge, a kettle and a coffeemaker are available) but it is also the room where we have our meetings and where we can work on our computers. There is the lab, where we have to wear protective equipment and respect basic rules.</p><br />
<br />
<p class="title3">Personal protective equipment</p><br />
<p class="texte">As soon as we manipulate in the lab, we have to wear the following personal protective equipment:</p><br />
<table><br />

</table><br />
<br />
<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />
<br><br />
Indeed, different machine are used to keep a sterile area.</p><br />
<br />
<p class="title3">Waste</p><br />
<p class="texte">Different trash containers are available in the lab:<br><br />
- One for biological waste (yellow). This waste will be autoclaved.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/f7/Yellow_trash.JPG"><br><br><br />
- One for common waste (green or orange).<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/c/c7/Black_garbage.png"><br><br><br />
- Special waste for chemicals.<br />
<br />
<p class="title3">Devices and Material</p><br />
<p class="texte">We use a lot of different devices, and each one involves a particular risk. Here we described how we use this material safely to reduce risks:</p><br />
<p class="title4">Chemical storage</p><br />
<p class="texte">We have three cupboards dedicated to the different kind of chemical products we use:<br><br />
- Flammable<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/35/Flammable.png"><br><br><br />
- Acids<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/36/Acids.png"><br><br><br />
- Bases<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/74/Bases.png"><br><br><br />
Those cupboards are key-closed.</p><br />
<br />
<p class="title4">Ethidium Bromide</p><br />
<p class="texte">We have a dark room dedicated to the use of EtBr and UV. This room is key-closed and everyone entering into the room must wear gloves, glasses and lab coat. Everything which is in direct contact with something in this room has to stay here.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/75/EtBr_room.JPG"><br><br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/4/45/EtBr_door.JPG"><br><br><br />
Two specific trash cans are dedicated to the gloves or paper and the agarose gels contaminated.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/fe/EtBr_garbage.JPG"><br><br></p><br />
<br />
<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />
<br />
<br />
<br />
<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="title1" id="select4">Team safety</p><br />
<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />

<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />
<br><br />
Indeed, different machine are used to keep a sterile area.</p><br />

<p class="title3">Waste</p><br />
<p class="texte">Different trash containers are available in the lab:<br><br />
- One for biological waste (yellow). This waste will be autoclaved.<br><br />

<p class="texte">We have a dark room dedicated to the use of EtBr and UV. This room is key-closed and everyone entering into the room must wear gloves, glasses and lab coat. Everything which is in direct contact with something in this room has to stay here.<br><br />

<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />

<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<p class="title1" id="select4">Team safety</p><br />
<p class="title2">Safety in INSA de Toulouse</p><br />
<p class="texte">INSA de Toulouse is a public school for engineers. The biosafety guidelines are not specific to our institution; the French regulations are applied.<br><br />
The regulation about the workers' prevention against risks resulting from their exposure to pathogenic biological agents (Decree No. 94-352 of 4 May 1994) includes microorganisms, cell cultures and human endoparasites which may cause infections, allergies or toxicity. <br><br />
This Decree is the French transposition of the Directive 90/679 / EEC and is also transcribed in the Labour Code (Articles L4421-1 R4421-1 to R4427-5.)<br><br />
The <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000465273&dateTexte=&categorieLien=id">Decree of the 16th July 2007</a> describes the technical preventive measuresto set up in research laboratories (including containment), education, analysis, anatomy and surgical pathology, autopsy rooms, and industrial and agricultural facilities where workers are likely to be exposed to biological pathogens.<br><br />
The rules of health, safety, and preventive medicine applied in public services in France (and thus in all public facilities working in scientific and technological domains) are set out in the <a href="http://www.legifrance.gouv.fr/affichTexte.do?cidTexte=LEGITEXT000006063791">Decree No. 82-453</a>. This decree refers to the Labour Code, Public Health Code and Environmental Code.<br><br />
The <a href="http://legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000024584737&categorieLien=id">Decree No. 2011-1177</a> is related to the use of genetically modified organisms.<br><br />
<br><br />
There is no one in charge of the biological safety at the INSA de Toulouse. However there is an organization which includes one prevention advisor and several prevention assistants in every structure. As far as the LISBP (our structure) is concerned, Nathalie Doubrovine is the prevention assistant.<br><br />
We have already discussed our project with her. She has given us the safety training and advices about how to respond to an imminent danger.<br><br />
She raised the problem of GMO and the related policy. Indeed she told us there is a special procedure for the destruction of GMO: we cannot wash this kind of organism down the drain.<br><br />
We were also informed about the potential chemical and microbiological risks thanks to her.<br><br />
<br><br />
The laboratory safety training requirements of the LISBP are detailed into the Rules of Procedure of the LISBP.<br><br />
The legislation requires employers to inform "all new employees" of the risks that they may encounter as well as ways to protect themselves from those risks. Therefore any newcomer must pass a practical and appropriate training in hygiene and safety to ensure its own safety and the one of his colleagues.<br><br />
Every person that enters in the LISBP has to make this training whatever its status (researcher, PhD student, trainee, etc.).<br><br />
The training is divided into two parts. The first one is a training concerning general risk prevention into research laboratories. This one is made individually thanks to the software NEO and with the explanations of the prevention assistant. The second one is a training about the techniques used during the occupation.<br><br />
<br><br />
All the team members have received this safety training. It lasts 1h30. It concerns fire risks, biological and chemical risks and good laboratory practices. We have made this training individually with a software designed by the CNRS and INSERM named NEO. This training ends with a questionnaire to check our knowledge. This questionnaire reminds us the basic safety rules in a molecular biology lab and gives us new knowledge about safety.<br><br />
We have also made a training to know how to sort out biological waste and how they are treated. We also learned that we cannot use autoclave by ourselves because a specific training is needed. We did not do this specific training.<br><br />
</p><br />

"If you don't think it's safe, it probably isn't"</p><br />
<p class="texte">We have organized our workspace. There is the relaxing room where no microbial material should enter. In this room, we can eat and drink (a fridge, a kettle and a coffeemaker are available) but it is also the room where we have our meetings and where we can work on our computers. There is the lab, where we have to wear protective equipment and respect basic rules.</p><br />
<br />
<p class="title3">Personal protective equipment</p><br />
<p class="texte">As soon as we manipulate in the lab, we have to wear the following personal protective equipment:</p><br />
<table><br />

</table><br />
<br />
<p class="title3">Basic rules in a lab</p><br />
<p class="texte">We have to apply the basic safety principles into a laboratory room:<br><br />
- It is forbidden to smoke in all the rooms.<br><br />
- It is forbidden to drink and eat in the laboratory rooms.<br><br />
- It is compulsory to wear a closed lab coat in cotton.<br><br />
- It is compulsory to wear closed shoes.<br><br />
- Long hair must be tied back.<br><br />
- Oral pipetting of any substance is prohibited in any laboratory.<br><br />
<br><br />
There is also others precaution when working with biological organisms:<br><br />
- We need to wash our hands regularly.<br><br />
- It is compulsory to wear gloves except with the use of an electric burner.<br><br />
- In some cases (UV light, projection risk), it is compulsory to wear protection glasses.<br><br />
<br><br />
Indeed, different machine are used to keep a sterile area.</p><br />
<br />
<p class="title3">Waste</p><br />
<p class="texte">Different trash containers are available in the lab:<br><br />
- One for biological waste (yellow). This waste will be autoclaved.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/f7/Yellow_trash.JPG"><br><br><br />
- One for common waste (green or orange).<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/c/c7/Black_garbage.png"><br><br><br />
- Special waste for chemicals.<br />
<br />
<p class="title3">Devices and Material</p><br />
<p class="texte">We use a lot of different devices, and each one involves a particular risk. Here we described how we use this material safely to reduce risks:</p><br />
<p class="title4">Chemical storage</p><br />
<p class="texte">We have three cupboards dedicated to the different kind of chemical products we use:<br><br />
- Flammable<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/35/Flammable.png"><br><br><br />
- Acids<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/3/36/Acids.png"><br><br><br />
- Bases<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/74/Bases.png"><br><br><br />
Those cupboards are key-closed.</p><br />
<br />
<p class="title4">Ethidium Bromide</p><br />
<p class="texte">We have a dark room dedicated to the use of EtBr and UV. This room is key-closed and everyone entering into the room must wear gloves, glasses and lab coat. Everything which is in direct contact with something in this room has to stay here.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/7/75/EtBr_room.JPG"><br><br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/4/45/EtBr_door.JPG"><br><br><br />
Two specific trash cans are dedicated to the gloves or paper and the agarose gels contaminated.<br><br />
<img width="150px" src="https://static.igem.org/mediawiki/2014/f/fe/EtBr_garbage.JPG"><br><br></p><br />
<br />
<p class="title4">Biological safety cabinet</p><br />
<p class="texte">We use a Biological safety cabinet (FASTER – Ultrasafe) to manipulate into a sterile area and thus avoid external contamination by unwanted microorganisms. We clean the bench of the BSC with ethanol before and after each manipulation. We also clean the BSC completely every two weeks. Because we work with fungi, we have to be very careful with the cleanliness of the BSC.</p><br />
<br />
<p class="title4">Electric burner</p><br />
<p class="texte">We also use electric burners to manipulate into a sterile area. The burning and fire risks are high but weaker than with a Bunsen Burner. We are very cautious when we use electric burners, and we use in preference BSC if it is possible. We do not have to wear gloves et we have to check that the electric burner is turned off after the manipulation.</p><br />
<br />
<p class="title4">Chemical hood</p><br />
<p class="texte">We use chemical hood in case we have to manipulate dangerous volatile chemical compound.</p><br />
<br />
<p class="title4">Water-bathes</p><br />
<p class="texte">The water-bathes are used extensively (transformation, digestion, etc.). However, they can be dangerous because of the exposition of boiling or hot water. We use special gloves for protecting us from heat, steam and projections. We take care of turning off the water-bathes at the end of the day.</p><br />
<br />
<br />
<br />
<p class="title2">Safety of our project</p><br />
<!--CITATION--><br />
<p class="citation"><br />
"Precaution is better than cure"</p><br />
<p class="texte">Several risks exist when working with microorganisms and manipulating genes. We can identify different classes of risk of our project now: <br><br />
- risks to the safety and health of team members, or other people working in the lab,<br><br />
- risks to the safety and health of the general public,<br><br />
- risks to the environment,<br><br />
- risks to security through malicious mis-use by individuals, groups, or countries.<br><br />
<br><br />
There are also risks in the Future, linked to our project’s growth (new knowledge and methods development).<br><br />
<br />
<p class="title3">Risks to the safety and health of team members, or other people working in the lab</p><br />
<p class="texte">We work with the <I>B. subtilis </I> and <i>E. coli</i> chassis. These organisms are non-pathogenic. Moreover the used parts are also non-pathogenic (the bio-fungicides produced are harmless for humans).<br><br />
On one hand, there is a major biological risk because of the manipulation of DNA and RNA of bacterial organisms.<br><br />
On the other hand the main risk for humans is chemical: we use Ethidium Bromide, hydrochloric acid, soda, solutions from a Miniprep kit, ethanol and bleach.<br><br />
<br><br />
However, we have a black room dedicated to the manipulation of Ethidium Bromide. Everything that touches something in this room cannot get out of the room. The waste has a special treatment.<br><br />
For the other chemical solutions, we always use gloves and glasses, and if necessary a hood.<br><br />
Furthermore, there are other risks such as UVs when we analyze an agarose gel but also water-bath and electrical/fire risks.<br><br />
For protecting us from the UVs, we use adapted glasses.<br><br />
At the end of every day, the last persons to leave check that everything is ok in the lab (no water-bath stayed on, everything disconnected).</p><br />
<br />
<p class="title3">Risks to the safety and health of the general public</p><br />
<p class="texte">If biological materials escape from our lab, the risks regarding safety and health of the general public is low because the manipulated parts are harmless. The only risk is the contact with DNA or RNA from a bacterial organism.<br><br />
Moreover, we have to be cautious with the use of antibiotics and we must not wash them down the drain.</p><br />
<br />
<p class="title3">Risks to the environment</p><br />
<p class="texte">If biological materials escape from our lab, GMOs can spread in the environment and gene transfer can occur. Moreover, the aim of our bacterial system (called SubtiTree) is to kill a fungus (Ceratocyctis platani). The risk to the environment is high because our system could perturb ecological niche and unbalance the environment of some plants. All our waste is autoclaved to minimize the risk for the environment.<br><br />
We use three fungicides.<br><br />
The first one, D4E1, is a synthetic peptide.<br><br />
The second is EcAMP-1 (BBa_K1162001), an AntiMicrobial Peptide from banyard grass added to the Registry last year by the team Utah State.<br><br />
The last one is GAFP-1, the Gastrodia AntiFungal Protein.<br><br />
These fungicides are not authorized yet by the European Union because they are not commercialized.</p><br />
<br />
<p class="title3">Risks to security through malicious mis-use by individuals, groups, or countries</p><br />
<p class="texte">If someone steals the biological material it could be dangerous for the environment because our bacterium will produce three bio-fungicides. This could lead to the disturbing of some ecosystems. <br><br />
However, the fungicides are natural and one of them is used in agriculture. With these considerations, we can assume that the risk is not very high for the chosen parts.</p><br />
<br />
<br />
<p class="title3">How to reduce these risks?</p><br />
<p class="texte">We take care of our waste and our biological material.<br><br />
We have chosen only non-pathogenic species to work on: <i>E. coli</i> and <i>B. subtilis</i>.<br><br />
We use non-pathogenic fungus to test our SubtiTree system: <i>Aspergillus brasiliensis</i>, <i>Chaetomium globosum</i>, <i>Trichoderma reesei</i> and <i>Aspergillus nidulans</i>.<br><br />
Indeed the targeted fungus, Ceratocystis platani, is pathogenic. Therefore we avoid working with it.</p><br />
<br />
<p class="title3">Risks in the Future</p><br />
<p class="texte">The system designed could be applied to many fungi. The fungicides used in our project are biological and specifically kill the fungi, and no other eukaryotic cells. <br><br />
However, a malicious person could replace these fungicides by others which are more dangerous. Indeed our problem is that there is no regulation of the production of fungicides.</p><br />
<br />
<p class="title3">How to reduce these Future risks?</p><br />
<p class="texte">We have thought about several ways to minimize risks: <br><br />
- we choose an auxotrophic strain of <I>B. subtilis</I>. The auxotrophy is for the glutamic acid, which is very present in plant's sap.<br><br />
- we choose a non-spore-forming strain of<I>B. subtilis</I>. The sporulation is the endophyte bacteria mechanism used to survive through winter. Thus, our bacterial system will be time limited.<br><br />
- we want to use a toxin/antitoxin system to avoid gene transfer between our optimized bacterium and another wild-type bacteria.</p><br />

<li class="tree"><p class="texte"><b>D4E1</b> is a synthetic peptide analog to Cecropin B AMPs (AntiMicrobial Peptides) made of 17 amino acids which has been shown to have an antifungal activity by complexing with a sterol present in the conidia’s wall of numerous fungi.</p></li><br />
<br />
<li class="tree"><p class="texte"><b>GAFP-1 </b>(<i>Gastrodia</i> Anti Fungal Protein 1), also known as gastrodianin, is a mannose and chitin binding lectin originating from the Asiatic orchid <i>Gastrodia elata</i>, a traditional Chinese medicinal herb cultured for thousands of years. GAFP-1 accumulates in nutritive corms where the fungal infection takes place, and <i>in vitro</i> assays demonstrated it can inhibit the growth of ascomycete and basidiomycete fungal plant pathogens.</p></li><br />

SubtiTree project<br />
</h1><br />
<p class="texte"><br></br><br />
Fungal diseases lead to major economic losses all over the world. Some pathogens trigger tracheomycosis by disturbing the vascular system of the plant. Canker is one of these infections especially affecting plane trees (<i>Platanus sp.</i>). Plane trees are widely present in Southern France and in particular along the famous Canal du Midi, participating to the site gorgeousness. Today, the only treatment consists in a costly preventive tree-cutting and implies significant ecological troubles. Facing this emergency, our team offers an innovative solution originating from synthetic biology. <br />

SubtiTree project<br />
</h1><br />
<p class="texte"><br></br><br />
Fungal diseases lead to major economic losses all over the world. Some pathogens trigger tracheomycosis by disturbing the vascular system of the plant. Canker is one of these infections especially affecting plane trees (<i>Platanus sp.</i>). Plane trees are widely present in Southern France and in particular along the famous Canal du Midi, participating to the site gorgeousness. Today, the only treatment consists in a costly preventive tree-cutting and implies significant ecological troubles. Facing this emergency, our team offers an innovative solution originating from synthetic biology. <br />

<p class="texte"><br></br><br />
Fungal diseases lead to major economic losses all over the world. Some pathogens trigger tracheomycosis by disturbing the vascular system of the plant. Canker is one of these infections especially affecting plane trees (<i>Platanus sp.</i>). Plane trees are widely present in Southern France and in particular along the famous Canal du Midi, participating to the site gorgeousness. Today, the only treatment consists in a costly preventive tree-cutting and implies significant ecological troubles. Facing this emergency, our team offers an innovative solution originating from synthetic biology. <br />

<p class="legend">Figure 1: Schema of the binding module</p><br />
<br />
<p class="texte"> In order to be highly efficient in the fight against the pythopathogen, our optimized bacterium has to be anchored to the fungus. Thus, we designed a chimeric protein (<a href="http://parts.igem.org/Part:BBa_K1364005"target="_blank">BBa_K1364005</a>) capable of building a <B>bridge between the bacterial peptidoglycan and the fungal chitin</B>, the main component of the pathogen’s cell wall. According to the work of <a href="https://2010.igem.org/Team:Imperial_College_London"target="_blank">the Imperial College 2010</a> iGEM team, we used the Cell Wall Binding (CWB) domain of the LytC protein (coding for a N-acetylmuramoyl-L-alanine amidase) to attach our chimeric protein to the <I>B. subtilis</I> cell wall. On the other side of our protein, we added the domain 4 of GbpA from <I>Vibrio cholerae</I>, which is known to recognize chitin.<br />
</p><br />
<br />
<br><br />
<p class="title1"> More information about this module </p><br />
<p class="texte"> <br />
The Binding Module ORF is composed of 3 sections:</p><br />
<br />
<ul><br />
<li class="tree"><p class="texte"><B>Anchor section</B>: the CWB (Cell Wall Binding) domain is extracted from LytC gene and composes the 5' side of our binding module. As previously described by the Imperial College of London 2010 iGEM team, we kept the first 318 bp. We can note the presence of the signal peptide at the beginning of the sequence, from 1 to 24 bp.</p></li><br />
<li class="tree"><p class="texte"><B>Chitin Binding Domain (CBD) section</b>: the domain 4 of GbpA from <I>Vibrio cholerae </I> is able to bind to N-Acetyl Glucosamine oligosacchararides. Also, the 3' side of our gene is composed by a part of the GbpA sequence (from 423 to 484 bp).</p></li><br />
<li class="tree"><p class="texte"><B>Helical Linker</B>: According to the work of the 2010 Imperial College of London iGEM team, we used the same six amino acids sequence (SRGSRA) to make a bridge between the Anchor section and the Chitin Binding section.<br />

<p class="texte"><br />
Among many other things, Southern France is well-known for the gorgeousness of its landscapes. Plane trees (<i>Platanus sp.</i>) are widely present and participate to the charm of this area, especially along the famous “Canal du Midi”. It is impossible to imagine this UNESCO World Heritage masterpiece without its trees. Unfortunately, these trees are threatened by a severe fungal infection called Canker Stain, and today the only treatment consists in a costly preventive tree-cutting and implies significant ecological troubles.<br />
</p><br />
<br />
<p class="texte"><br />
Facing this emergency, the students from the iGEM Toulouse Team decided to be committed to the protection of their local heritage. Using a bacterium vector naturally present in the trees, our team offers an alternative solution originated from synthetic biology. Using different genetic modules, we engineered a bacterium (SubtiTree) capable of heading towards the pathogen, binding to its cell wall and finally delivering different fungicides to save the tree from its invaders. Our team also began to design genetic modules preventing any accidental spreading of the optimized microorganism, thus limiting the ecological and ethical footprints of SubtiTree. Although our project originated from a very local and specific tree disease, it could be transposable to other plant diseases.<br />
</p><br />
<br />
<br />
<p class="title1">Choice of the chassis </p><br />
<p class="texte"><i>Bacillus subtilis</i> has been reported to be an endophyte bacterium of a large variety of plants and trees. Therefore, this model organism is a perfect chassis for our project. Already used to treat plant diseases and fungal pathogens, we aim to engineer <i>Bacillus subtilis</i> to fight Canker Stain inside of the tree.

<p class="texte">One of Europe Wonders is without a doubt the Toulouse Canal du Midi. Situated in the heart of our city and going through Southern France, our lab is only 5 minutes walk from the Canal du Midi. Everyone in the team could enjoy the quietness and loveliness of this charming place. Unfortunately, this heritage is threatened: a phytopathogenic fungus, <i>Ceratocystis platani</i>, is devastating the trees lining the Canal.<br />
</p><br />
<br />
<center><img src="https://static.igem.org/mediawiki/2014/1/14/Overview_context.jpg"/></center><br />
<br></br><br />
<br />
<p class="texte">The situation is alarming: today the only solution is preventive tree cutting to stem the fungal epidemic. The consequences are disastrous. Not only for the beauty of the landscapes but it has also huge environmental, social and economic costs. Today, 42,000 plane trees are threatened, knowing that cutting and planting a new resistant tree is about €4,000.<br />
</p><br />
<br />
<p class="title1">The Canal du midi</p> <br />
<div style="float:right; margin-left:40px"><img style="width:300px;" src="https://static.igem.org/mediawiki/2014/0/04/Canal_automnal.jpg"></div><br />
<p class="texte" style="display:block; float: left; width: 600px;">This ingenious masterpiece respects the environment in which it is harmoniously integrated since 1681 by Pierre-Paul Riquet.<br />
Characterized as a summit level canal, it culminates at 189 meters of altitude and permits the achievement of water through the sea.<br />
In December 7th 1996, the UNESCO registers Le Canal du Midi on the list of world’s legacy. The first plane trees bordering the channel appeared lately after its creation in 1776. Resolving the erosion of riverbanks and the evaporation of the water, the plane imposes itself as a dominant and emblematic marrow. The wooded legacy is estimated to about 42,000 trees, it contributes to the landscape and aesthetic.<br />
Today, the canal du midi is primarily used for tourism, recreation and housing. Busier than the Seine (Paris river), it accounts for one fifth of French river tourism and 80 % tourists are foreigners. Boaters seeking for tranquility, quietness and a unique environment mainly navigate over it.<br />

<p class="title1">Canker Stain</p> <br />
<div style="float:left; width:215px; margin-right:40px"><img style="width:200px; float:left;" src="https://static.igem.org/mediawiki/2014/5/5e/Ceratocystis.jpg"></div><br />
<p class="texte">The canker stain is a disease caused by <i>Ceratocystis platani</i>, a microscopic fungus that exclusively attacks Plane Trees.<br />
Probably introduced in France by infected wooden munitions cases coming from United States of America in 1945, the fungus introduces itself inside the sain tree’s heart, blocks the sap flow and kills it in only 2 to 5 years.<br />
On the regulatory side, on July 31th 2000 a ministerial order has classed <I>Ceratocystis platani</I> as an harmful organism for plants. This order leads to a mandatory fight against the fungus.<br />
</p><br />
<br />
<br></br><br />
<br />
<p class="title1">Fighting the plane trees pathogen</p> <br />
<p class="texte">Regarding this imminent threat, some solutions emerged.<br />
</br>First of all, chemical fungicides were used. However, the community realized it was impossible to eradicate the whole fungus. <br />
</br>Therefore, the French Institut National de Recherche Agronomique (INRA) created a new type of plane trees named Platanor which were resistant to the fungus infection. Unfortunately, this extreme measure could not save the already contaminated trees nearby the Canal du Midi.<br />
</br>Today, the only option remains in the tree-cutting of the contaminated plane trees. Nevertheless, this previous solution is not optimal because of the high cost and the major ecological, touristic and social impact for our heritage.<br />

<p class="legend">Figure 1: Schema of the chemotaxis module</p><br />
<br />
<p class="title1">What is chemotaxis?</p><br />
<br />
<p class="texte"><br />
Chemotaxis is a bacterial function which allows moving toward a gradient of concentration of a molecule that is present in the medium. With this system bacteria can swim to a location containing higher concentrations of molecules such as sugar, amino acid, vitamins... Chemotactic-signal transducers respond to changes in the concentration of attractants and repellents in the environment, transduce the signal from the outside to the inside of the cell, and facilitate sensory adaptation through the variation of the level of methylation. <br />
<br />
<p class="title1">More information on this module</p><br />
<p class="texte"><br />
Chemotaxis is used as a way to detect and come close to the location of fungi infection. During its growth, fungi release N-acetylglucosamine (NAG), the basic unit of chitin which composed its cell wall. Thus, there should exist a gradient of the concentration of NAG around the fungi.</p><br />
<p class="texte"><br />
It is known that <i>B. subtilis</i> is able to detect and to swim towards glucose using the Methyl-accepting chemotaxis protein, called <b>McpA</b>.<br><br />
Some bacteria are attracted by NAG, like <i>Vibrio cholerae</i> which has a NAG regulated methyl-accepting chemotaxis protein: <b>VCD</b>.</p><br />

<p class="legend">Figure 2: Chimeric protein of chemotaxis</p><br />
<br />
<p class="texte"><br />
Therefore, our idea is to switch the natural glucose specificity of <i>B. subtilis'</i> McpA to a NAG specificity. To achieve this, we need to change the extracellular domain of McpA, the domain responsible for the specificity, by the extracellular domain of VCD.<br />
The whole sequence has been designed <i>in silico</i> and codon optimized for the transcription in <i>B. subtilis</i> before its synthesis.</p><br />

Among many other things, Southern France is well-known for the gorgeousness of its landscapes. Plane trees (<i>Platanus sp.</i>) are widely present and participate to the charm of this area, especially along the famous “Canal du Midi”. It is impossible to imagine this UNESCO World Heritage masterpiece without its trees. Unfortunately, these trees are threatened by a severe fungal infection called Canker Stain, and today the only treatment consists in a costly preventive tree-cutting and implies significant ecological troubles.<br />
</p><br />
<br />
<p class="texte"><br />
Facing this emergency, the students from the iGEM Toulouse Team decided to be committed to the protection of their local heritage. Using a bacterium vector naturally present in the trees, our team offers an alternative solution originated from synthetic biology. Using different genetic modules, we engineered a bacterium (SubtiTree) capable of heading towards the pathogen, binding to its cell wall and finally delivering different fungicides to save the tree from its invaders. Our team also began to design genetic modules preventing any accidental spreading of the optimized microorganism, thus limiting the ecological and ethical footprints of SubtiTree. Although our project originated from a very local and specific tree disease, it could be transposable to other plant diseases.<br />

<p class="title1">Choice of the chassis </p><br />
<p class="texte"><i>Bacillus subtilis</i> has been reported to be an endophyte bacterium of a large variety of plants and trees. Therefore, this model organism is a perfect chassis for our project. Already used to treat plant diseases and fungal pathogens, we aim to engineer <i>Bacillus subtilis</i> to fight Canker Stain inside of the tree. Injected directly in the tree sap, our smart bacterium will act as a curative and preventive drug.</p><br />

<p class="texte">First, the bacterium targets the pathogen with a chemotaxis module which recognizes the soluble molecules released by the fungus' cell wall (N-acetylglucosamine).</p><br />

<br />
<p class="texte">Then, SubtiTree binds onto the pathogen using a chimeric protein anchored to the bacterium peptidoglycan and which can make a bridge between bacterial cell wall and fungal chitin, the main component of the pathogen's cell wall.</p><br />
<br />
<p class="title1">Fungicides<a href="https://2014.igem.org/Team:Toulouse/Project/Fungicides"; style="font-size: 13px; cursor: pointer; color: #888; margin-left: 10px;"> Show more</a></p><br />

<p class="texte">In the third step, our designed bacterium fights the pathogen by production of a powerful treatment based on the release of three different fungicides.</p><br />

<p class="texte">Our team worked on different aspects to control SubtiTree released in the environment. The aim is to prevent horizontal transfers between different bacteria and limit the growth and survival of the engineered bacterium inside the tree during one season.</p><br />

<p class="texte">One of Europe Wonders is without a doubt the Toulouse Canal du Midi. Situated in the heart of our city and going through Southern France, our lab is only 5 minutes walk from the Canal du Midi. Everyone in the team could enjoy the quietness and loveliness of this charming place. Unfortunately, this heritage is threatened: a phytopathogenic fungus, <i>Ceratocystis platani</i>, is devastating the trees lining the Canal.<br />
</p><br />

<p class="texte">The situation is alarming: today the only solution is preventive tree cutting to stem the fungal epidemic. The consequences are disastrous. Not only for the beauty of the landscapes but it has also huge environmental, social and economic costs. Today, 42,000 plane trees are threatened, knowing that cutting and planting a new resistant tree is about €4,000.<br />
</p><br />
<br />
<p class="title1">The Canal du midi</p> <br />
<div style="float:right; width:215px; margin-left:40px"><img style="width:300px; float:left;" src="https://static.igem.org/mediawiki/2014/0/04/Canal_automnal.jpg"></div><br />
<p class="texte" style="display:block; float: left; width: 700px;">This ingenious masterpiece respects the environment in which it is harmoniously integrated since 1681 by Pierre-Paul Riquet.<br />
Characterized as a summit level canal, it culminates at 189 meters of altitude and permits the achievement of water through the sea.<br />
In December 7th 1996, the UNESCO registers Le Canal du Midi on the list of world’s legacy. The first plane trees bordering the channel appeared lately after its creation in 1776. Resolving the erosion of riverbanks and the evaporation of the water, the plane imposes itself as a dominant and emblematic marrow. The wooded legacy is estimated to about 42,000 trees, it contributes to the landscape and aesthetic.<br />
Today, the canal du midi is primarily used for tourism, recreation and housing. Busier than the Seine (Paris river), it accounts for one fifth of French river tourism and 80 % tourists are foreigners. Boaters seeking for tranquility, quietness and a unique environment mainly navigate over it.<br />

<p class="title1">Canker Stain</p> <br />

<p class="texte">The canker stain is a disease caused by <i>Ceratocystis platani</i>, a microscopic fungus that exclusively attacks Plane Trees.<br />
Probably introduced in France by infected wooden munitions cases coming from United States of America in 1945, the fungus introduces itself inside the sain tree’s heart, blocks the sap flow and kills it in only 2 to 5 years.<br />
On the regulatory side, on July 31th 2000 a ministerial order has classed <I>Ceratocystis platani</I> as an harmful organism for plants. This order leads to a mandatory fight against the fungus.<br />
</p><br />
<br />
<br></br><br />
<br />
<p class="title1">Fighting the plane trees pathogen</p> <br />
<p class="texte">Regarding this imminent threat, some solutions emerged.<br />
</br>First of all, chemical fungicides were used. However, the community realized it was impossible to eradicate the whole fungus. <br />
</br>Therefore, the French Institut National de Recherche Agronomique (INRA) created a new type of plane trees named Platanor which were resistant to the fungus infection. Unfortunately, this extreme measure could not save the already contaminated trees nearby the Canal du Midi.<br />
</br>Today, the only option remains in the tree-cutting of the contaminated plane trees. Nevertheless, this previous solution is not optimal because of the high cost and the major ecological, touristic and social impact for our heritage.<br />

<p class="texte"> In order to be highly efficient in the fight against the pythopathogen, our optimized bacterium has to be anchored to the fungus. Thus, we designed a chimeric protein (<a href="http://parts.igem.org/Part:BBa_K1364005"target="_blank">BBa_K1364005</a>) capable of building a <B>bridge between the bacterial peptidoglycan and the fungal chitin</B>, the main component of the pathogen’s cell wall. According to the work of <a href="https://2010.igem.org/Team:Imperial_College_London"target="_blank">the Imperial College 2010</a> iGEM team, we used the Cell Wall Binding (CWB) domain of the LytC protein (coding for a N-acetylmuramoyl-L-alanine amidase) to attach our chimeric protein to the <I>B. subtilis</I> cell wall. On the other side of our protein, we added the domain 4 of GbpA from <I>Vibrio cholerae</I>, which is known to recognize chitin.<br />

<br><br />
<p class="title1"> More information about this module </p><br />
<p class="texte"> <br />
The Binding Module ORF is composed of 3 sections:</p><br />
<br />
<ul><br />
<li class="tree"><p class="texte"><B>Anchor section</B>: the CWB (Cell Wall Binding) domain is extracted from LytC gene and composes the 5' side of our binding module. As previously described by the Imperial College of London 2010 iGEM team, we kept the first 318 bp. We can note the presence of the signal peptide at the beginning of the sequence, from 1 to 24 bp.</p></li><br />
<li class="tree"><p class="texte"><B>Chitin Binding Domain (CBD) section</b>: the domain 4 of GbpA from <I>Vibrio cholerae </I> is able to bind to N-Acetyl Glucosamine oligosacchararides. Also, the 3' side of our gene is composed by a part of the GbpA sequence (from 423 to 484 bp).</p></li><br />
<li class="tree"><p class="texte"><B>Helical Linker</B>: According to the work of the 2010 Imperial College of London iGEM team, we used the same six amino acids sequence (SRGSRA) to make a bridge between the Anchor section and the Chitin Binding section.<br />

<br>The binding module has been placed under the control of Pveg (<a href="http://parts.igem.org/Part:BBa_K143012"target="_blank">BBa_K143012</a>), a strong constitutive promoter and we used a consensus RBS (<a href="http://parts.igem.org/Part:BBa_K090505"target="_blank">BBa_K090505</a>) and a double terminator (<a href="http://parts.igem.org/Part:BBa_B0015"target="_blank">B0015</a>). The construct has been inserted in an integrative plasmid, pSBBS4S (<a href="http://parts.igem.org/Part:BBa_K823022"target="_blank">BBa_K823022</a>) which comes from the LMU-Munich 2012 iGEM team.</p> <br />

<p class="texte"><br></br><br />
Fungal diseases lead to major economic losses all over the world. Some pathogens trigger tracheomycosis by disturbing the vascular system of the plant. Canker is one of these infections especially affecting plane trees (<i>Platanus sp.</i>). Plane trees are widely present in Southern France and in particular along the famous Canal du Midi, participating to the site gorgeousness. Today, the only treatment consists in a costly preventive tree-cutting and implies significant ecological troubles. Facing this emergency, our team offers an innovative solution originating from synthetic biology. <br />

Fungal diseases lead to major economic losses all over the world. Some pathogens trigger tracheomycosis by disturbing the vascular system of the plant. Canker is one of these infections especially affecting plane trees (<i>Platanus sp.</i>). Plane trees are widely present in Southern France and in particular along the famous Canal du Midi, participating to the site gorgeousness. Today, the only treatment consists in a costly preventive tree-cutting and implies significant ecological troubles. Facing this emergency, our team offers an innovative solution originating from synthetic biology. <br />

<p class="texte"><br />
Among many other things, Southern France is well-known for the gorgeousness of its landscapes. Plane trees (<i>Platanus sp.</i>) are widely present and participate to the charm of this area, especially along the famous “Canal du Midi”. It is impossible to imagine this UNESCO World Heritage masterpiece without its trees. Unfortunately, these trees are threatened by a severe fungal infection called Canker Stain, and today the only treatment consists in a costly preventive tree-cutting and implies significant ecological troubles.<br />
</p><br />
<br />
<p class="texte"><br />
Facing this emergency, the students from the iGEM Toulouse Team decided to be committed to the protection of their local heritage. Using a bacterium vector naturally present in the trees, our team offers an alternative solution originated from synthetic biology. Using different genetic modules, we engineered a bacterium (SubtiTree) capable of heading towards the pathogen, binding to its cell wall and finally delivering different fungicides to save the tree from its invaders. Our team also began to design genetic modules preventing any accidental spreading of the optimized microorganism, thus limiting the ecological and ethical footprints of SubtiTree. Although our project originated from a very local and specific tree disease, it could be transposable to other plant diseases.<br />
</p><br />
<br />
<br />
<p class="title1">Choice of the chassis </p><br />
<p class="texte"><i>Bacillus subtilis</i> has been reported to be an endophyte bacterium of a large variety of plants and trees. Therefore, this model organism is a perfect chassis for our project. Already used to treat plant diseases and fungal pathogens, we aim to engineer <i>Bacillus subtilis</i> to fight Canker Stain inside of the tree. Injected directly in the tree sap, our smart bacterium will act as a curative and preventive drug.</p><br />

<br />
<p class="texte">Then, SubtiTree binds onto the pathogen using a chimeric protein anchored to the bacterium peptidoglycan and which can make a bridge between bacterial cell wall and fungal chitin, the main component of the pathogen's cell wall.</p><br />

<p class="texte">Our team worked on different aspects to control SubtiTree released in the environment. The aim is to prevent horizontal transfers between different bacteria and limit the growth and survival of the engineered bacterium inside the tree during one season.</p><br />

Today, 42,000 plane trees are threatened, knowing that cutting and planting a new resistant tree is about €4,000.<br />

<p class="title1">The Canal du midi</p> <br />

<p class="texte">This ingenious masterpiece respects the environment in which it is harmoniously integrated since 1681 by Pierre-Paul Riquet.<br />
Characterized as a summit level canal, it culminates at 189 meters of altitude and permits the achievement of water through the sea.<br />
In December 7th 1996, the UNESCO registers Le Canal du Midi on the list of world’s legacy. The first plane trees bordering the channel appeared lately after its creation in 1776. Resolving the erosion of riverbanks and the evaporation of the water, the plane imposes itself as a dominant and emblematic marrow. The wooded legacy is estimated to about 42,000 trees, it contributes to the landscape and aesthetic.<br />
Today, the canal du midi is primarily used for tourism, recreation and housing. Busier than the Seine (Paris river), it accounts for one fifth of French river tourism and 80 % tourists are foreigners. Boaters seeking for tranquility, quietness and a unique environment mainly navigate over it.<br />

<p class="title1">Canker Stain</p> <br />
<div style="float:left; width:215px; margin-right:40px"><img style="width:200px; float:left;" src="https://static.igem.org/mediawiki/2014/5/5e/Ceratocystis.jpg"></div><br />
<p class="texte">The canker stain is a disease caused by <i>Ceratocystis platani</i>, a microscopic fungus that exclusively attacks Plane Trees.<br />
Probably introduced in France by infected wooden munitions cases coming from United States of America in 1945, the fungus introduces itself inside the sain tree’s heart, blocks the sap flow and kills it in only 2 to 5 years.<br />
On the regulatory side, on July 31th 2000 a ministerial order has classed <I>Ceratocystis platani</I> as an harmful organism for plants. This order leads to a mandatory fight against the fungus.<br />

<p class="title1">Fighting the plane trees pathogen</p> <br />
<p class="texte">Regarding this imminent threat, some solutions emerged.<br />
</br>First of all, chemical fungicides were used. However, the community realized it was impossible to eradicate the whole fungus. <br />
</br>Therefore, the French Institut National de Recherche Agronomique (INRA) created a new type of plane trees named Platanor which were resistant to the fungus infection. Unfortunately, this extreme measure could not save the already contaminated trees nearby the Canal du Midi.<br />
</br>Today, the only option remains in the tree-cutting of the contaminated plane trees. Nevertheless, this previous solution is not optimal because of the high cost and the major ecological, touristic and social impact for our heritage.<br />
