The biochemical mechanisms of plastic biodegradation
AI summary Read the abstract
This review comprehensively maps the biochemical pathways by which microorganisms break down synthetic plastics, ranking the most effective biodegrading organisms for each major plastic type and cataloging experimental techniques used in the field to guide future biodegradation research.
Since the invention of the first synthetic plastic, an estimated 12 billion metric tons of plastics have been manufactured, 70% of which was produced in the last 20 years. Plastic waste is placing new selective pressures on humans and the organisms we depend on, yet it also places new pressures on microorganisms as they compete to exploit this new and growing source of carbon. The limited efficacy of traditional recycling methods on plastic waste, which can leach into the environment at low purity and concentration, indicates the utility of this evolving metabolic activity. This review will categorize and discuss the probable metabolic routes for each industrially relevant plastic, rank the most effective biodegraders for each plastic by harmonizing and reinterpreting prior literature, and explain the experimental techniques most often used in plastic biodegradation research, thus providing a comprehensive resource for researchers investigating and engineering plastic biodegradation.

Bacterial biodegradation of synthetic plastics: a review
AI summary Read the abstract
This review examines how bacteria break down synthetic plastics through a four-step process — biodeterioration, depolymerization, assimilation, and mineralization — using specialized enzymes as part of metabolic pathways. While bacterial biodegradation offers an eco-friendly alternative to plastic waste management, the process remains slow and faces real-world limitations that require further research to overcome.
