WUST-China # Plastic Killer # WUST-China incorporated PETase and MHETase into Rhodococcus rhodococcus PD630 to break down PET and yield ethylene glycol (EG) and terephthalic acid (TPA). Additionally, they explored various promoters, signal peptides, and enhancers to enhance the breakdown of PET plastics. At the same time, the method introduced 1,2 dioxygenase to transform degradation-generated TPA into protocatechuic acid PCA, thus enabling Rhodococcus rhodococcus to effectively use PET and accumulate microbial lipids. ...

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. ...
