Microbial Degradation of Plastics

Microbial degradation in the environment is initiated by abiotic (nonliving physical or chemical) processes. Mechanical weathering and other mechanical processes are the main drivers of the initial degradation. This article presents an overview of weathering and biodegradation. It summarizes the main synthetic polymers that are released and available for bacterial and fungal decomposition. The article also presents a detailed discussion on the enzymes that are involved in plastic degradation, and the measurement of polymer degradation.
