Abstract With the intensification of the global plastic pollution, the rate and mechanism of microbial degradation of Poly (butylene adipate terephthalate) (PBAT), a representative of biodegradable plastics, have received increasing attention. Here we compare the degradation patterns of PBAT in water, soil, and compost environments, analyze the effects of different factors on the microbial degradation PBAT, summarizes the PBAT-degrading bacteria that have been screened so far and compares their degradation speeds, and elucidate the PBAT modification mechanism and modification products at both extracellular and intracellular levels. Finally, we proposed future research directions from the aspects of research on influencing factors, unification of PBAT degradation indicators, construction of microbial community, and exploration technology of PBAT degradation mechanism.

Key words： poly (butylene adipate terephthalate) microbial degradation highly efficient degrading bacteria hydrolysis extracellular enzyme
