<p> The usage of polyethylene terephthalate-PET (as like plastic bottles or textiles) is one of the big problems of our era. Many plastic bottles are not reusable and are not safe for hot liquids or for use in dishwashers or microwaves. Some tougher, reusable plastic bottles may cause cancer. The main disadvantage of plastic bottles is that so many of them end up in landfills instead of being recycled. It takes thousands of years for plastic bottles to biodegrade, and the degrading process emits toxic chemicals into the air. | <p> The usage of polyethylene terephthalate-PET (as like plastic bottles or textiles) is one of the big problems of our era.

+ | <p>Degrado PETronum | ||
+ | La présence de poly-téréphtalate d'éthylène (PET) dans le plastique, comme celui des bouteilles, est l’un des problèmes majeurs de notre époque. La plupart des bouteilles plastiques ne sont pas réutilisables. Et les plus robustes, réutilisables, pourraient être impliquées dans des cancers. Le principal inconvénient des bouteilles en plastique est que nombre d'entre elles finissent dans les décharges au lieu d'être recyclées. Il faut plusieurs centaines d’années pour que ces bouteilles se dégradent,et leur dégradation est à l’origine d’émission de toxine dans l’air. | ||
+ | Grâce à ce projet, l’environnement serait débarrassé des PET tout en produisant du pyruvate qu'E.coli serait capable d’utiliser comme source de d’énergie en l’incorporant à son cycle cellulaire. | ||
+ | Nous allons dégrader le PET en catéchol. Puis, ce catéchol résultera en pyruvate par le 2-hydroxymuconate.</p> | ||

With this project,while the environment will be cleaned from PET, the E.coli would add pyruvate to the cell cycle and use it as a new source. | <p> Our project aims to clean enviroment with the degredation of PET to pyruvate by E.coli.

+ | <p>We made a design for collected plastic and aim to having a bacteria pool of plastic which our organism degredate PET without producing toxic material. In this design, controlled biodegradation is very important because we can not precise all the risks. So, we made our organism addicted, briefly it works with a kill-switch mechanism with the presence of arabinose.</p> | ||

+ | |||
+ | <h3>Can our bacteria degrade PET in huge amounts?</h3> | ||
+ | <p>For nowadays, yes. Also we can do this biodegradation process with different organisms like algeas in water. For soil, situation is more complicated but actually, we try to obtain this biodegradation genes from a soil organism Pseudomonas putita. E.coli can be worked as easy as P. putida and has a good adaptiton. If we talk about a biodegradation on a collected plastic, our project would work properly.</p> | ||
+ | |||
+ | <h3>Why did we associated some of our parts with Pseudomonas putida F1 strain?</h3> | ||
+ | <p>P. putida is used for related experiments and it has lots of metabolic similarities with E.coli</p> | ||
+ | |||
+ | <h3>Which teams worked on the previous parts of our project?</h3> | ||
+ | <p>With the experiments of Darmstadt, London Imperial college and UC_Davis Teams and other iGEM parts, we can obtain catechol from PET. For going further, we ligated K316003 part with a constitutive promoter. So, we reduced huge amounts of catechol into 2-hydroxymuconate Semialdehyde and obtained green colour as we expected. Then, we designed a new part | ||

+ | From http://parts.igem.org/Part:BBa_K316003 and Bba_K316003 http://parts.igem.org/Part:BBa_K936020 and Bba_K936020 | ||
+ | With these parts, we can obtain catechol from PET. Our project starts after catechol and we aim reduce catechol to pyruvate to add cell metabolism!</p> | ||
+ | <h3>Our Future Aspect:</h3> | ||
+ | <p>In our early rough drafts’ of our project we focused on PET degredation until Catechol but when we obtained that Catechol can not use in biological pathways as biproduct, we decided to focus on PET degredation until pyruvate which is a substance that can be used by organisms directly in their metabolic pathways. | ||
+ | We knew from our researchs of past iGEM projects, there are some great projects about generating electric from E. coli and some other microorganisms by MFC. MFC (Microbial Fuel Cell) can be utilized for electric generation through the conversion of organic and inorganic substrates by microorganisms. | ||
+ | We read wiki sites of some iGEM teams ,especially Bielefeld 2013 and TU Darmstadt, which was about generating electricity through MFC. | ||
+ | We know that through the reactions of PET degradation until pyruvate, after pyruvate metabolism there is overproduction of H ions and we think that excessive H ions can generate potential difference which can be further used for electric generation. | ||
+ | Can you imagine we can live in such a world, while generating electricity it destroys all plastic wastes!</p> | ||
