Microorganisms: Promising approach to quench plastic pollution
This review surveys the range of bacteria and fungi — including Pseudomonas, Bacillus, and several fungal phyla — that are capable of degrading plastics including polyethylene, the world's most produced plastic. Microbial biodegradation is presented as a promising complement to physical and chemical recycling methods, with the potential to address plastic pollution already dispersed in the environment. Harnessing these organisms could eventually provide biological tools to break down plastic waste that has entered soils, waterways, and the ocean.
