Abstract
The present disclosure discloses Microbacterium oleivorans capable of degrading polyethylene terephthalate and an intermediate thereof, and belongs to the technical field of microorganisms. The present disclosure provides Microbacterium oleivorans JWG-G2 capable of degrading the polyethylene terephthalate. After Microbacterium oleivorans JWG-G2 is inoculated into an inorganic salt liquid medium containing 2 g/L polyethylene terephthalate plastic particles with an inoculation quantity of 1×108 CFU/mL to be cultivated for 5 d, the polyethylene terephthalate plastic particles can be partially degraded into monohydroxyethyl terephthalate and terephthalic acid capable of being directly recycled, ester bond functional groups on surfaces of the polyethylene terephthalate plastic particles can be reduced, and a weight loss ratio of the polyethylene terephthalate plastic particles can reach 5.6%. Therefore, Microbacterium oleivorans JWG-G2 of the present disclosure has an extremely high application prospect in degradation of the polyethylene terephthalate.
