Abstract
Disclosed herein are engineeredKT2440 co-expressing PETase and MHETase enzymes that selectively degrades PET into monomers, ethylene glycol and terephthalate (TPA). In another embodiment, disclosed herein are methods for making and using a highly efficient EG metabolizingKT2440 strain. Given that nativedoes not have a TPA metabolic pathway, nor the proteins to transport TPA into the cell, the next metabolic engineering challenge for developing syntheticstrain to plastic upcycling was enabling TPA catabolisminKT2440. TPA transporters and catabolic pathway have been characterized in several microorganisms includingsp. strain E6 andRHA1.
