Queens-Canada # Recircuit # Through Recircuit, we will bridge the gap caused by plastic’s resilience to degradation and cost to recycle by engineering a bacterium that uses PET plastic, found in clear water bottles, as a feedstock for PHB synthesis, a type of bioplastic. Recycling with a biological system not only could be cheaper than chemical methods, but such a system can repurpose PET, which takes hundreds of years to degrade, into a more environmentally friendly alternative that takes just a few weeks. ...

WVHS-SanDiego # Introducing PETase and MHETase into Alteromonas # The abundance of polyethylene terephthalate (PET) plastics in the oceans cause issues for all types of life. The sequential enzymes, PETase and MHETase, found in the soil bacterium Ideonella sakaiensis, have shown degradation of PET plastics through metabolic activity. However, because I. sakaiensis is found mainly in soil, it is not an ideal host when attempting to degrade PET plastics in the ocean. ...
