<h4> <u>Tests of antibiotics' stocks</u> </h4>
 
-
 
-
Six plates of LB agar were made.
 
-
Five of them contained one of those antibiotics in the dilution 1:1000:
 
-
<ul>
 
-
<li> Chloramphénicol
 
-
<li> Kanamycin
 
-
<li> Erythromycin
 
-
<li> Ampicilin
 
-
<li> Tetracyclin
 
-
</ul>
 
-
(The last one was the control of the growth of our bacteria without antibiotics)
 
-
We sowed 10µL of a liquid LB culture of Bl21, and we let them incubate overnight at 37°C.
 
-
 
-
<h4> <u>Survivability tests</u> </h4>
 
-
Two plates of MB 1X and M9 1X were made and divised in two parts.
 
-
Each plate was sowed with 5µL of a liquid MB 1X culture of Pseudovibrio denitrificans(dated 12th August) in a part and with 5µL of a liquid M9 1X culture Pseudovibrio denitrificans (dated 12th August) in the other part.
 
-
 
-
<h4> <u>Pre-cultures</u> </h4>
 
-
Cultures in MB 1X and M9 1X of Pseudovibrio were passed by a 1/10 dilution and let incubate overnight at 30°C.
 
-
New cultures of different E.Coli were also started from glycerol or plate and let incubated overnight at 37°C.
 
-
<u>From glycerol stocks:</u>
 
-
<ul>
 
-
<li>Bl21
 
-
<li>Top10
 
-
<li>DH5a
 
-
</ul>
 
-
<u>From plates:</u>
 
-
<ul>
 
-
<li>DH5a tranformed with pCB1C3
 
-
<li>Top10 transformed with pQexp
 
-
<li>DH5a pyr tranformed with pMK2
 
-
</ul>
 
-
Bacteria tranformed with plasmid were cultivated with the corresponding antibiotic for the selection.
 
-
For each medium we make a negative contrôle without bacteria.

There was a problem with the stock of Kanamycine so we made a new one at 25mg/mL.
 
-
For the erythrompycine, we learn that E. Coli is not really sensitive to this antibiotic and that it's better to use it  with a dilution at 1:100

Any liquid culture can be plated and will grow up. Of course, it works better on MB medium, wich is a rich medium than on M9.

<h4> <u>Launch of antibiotics's tests in liquid M9 1X</u> </h4>
 
-
 
-
For each tested antibiotic we made the following range of concentrations:
 
-
<table border="1">

<tr >

  <td> <b>0 </b> </td>

  <td> <b>1:500 </b> </td>

  <td> <b>1:100 000 </b> </td>
 
-
</tr>
 
-
</table>
 
-
We made these range two time to have a replicate and we added a controle tube without antibiotic for each bacteria.
 
-
 
-
Each tube is made like in the following table in Falcon tubes (15mL):

For each range, we test Pseudovibrio denitrificans but also E.Coli and E.Coli tranformed with a speicific resistance cassette (NM:The E.Coli strain for the control case is the same strain that is tranformed for the cassette efficiency test)
 
-
The initial OD at 600nm of each bacteria has been mesured to after be able to calculate the ΔOD at 600nm, during three days.

<h4> <u>Plates for antibiotics's tests</u> </h4>
 
-
 
-
For each tested antibiotic we made the same range of concentrations than in liquid.
 
-
We also made these range two time to have a replicate and we added a controle plate without antibiotic on which we showed all our tested bacteria. Plates will be checked during three days.
 
-
We made these same ranges of tested antibiotic's concentrations for three media:
 
-
<ul>
 
-
<li>MB agar 1X
 
-
<li>MB agar 0.5X
 
-
<li>M9 agar 1X
