Summary

This book chapter reviews the characteristics of microbial plastic degradation, covering the enzymes, metabolic pathways, and environmental conditions that affect breakdown rates for different polymer types. Understanding microbial degradation mechanisms is foundational to developing biological solutions for microplastic pollution.

The increase in the amount of plastic waste, especially microplastics and the environmental pollution caused by it has diverted the research focus of the world into plastic recycling and degradation. Hence in the last decade, different strategies have been adopted to combat this problem. Albeit many physiochemical technologies are there for the degradation of plastics, they give rise to harmful chemicals as by-products. This has shifted the priority of our research to the biodegradation of plastics by microbes. In fact, in the last decade, many microorganisms have been discovered with the ability to degrade many conventional plastics with moderate efficiency but longer duration. The initial part of this chapter discusses the various kinds of plastics present and the methods adopted for the degradation of plastics, with special emphasis on the factors affecting plastic degradation. In the subsequent section, the microbial degradation of different plastics by bacteria and fungi, along with a mechanism, has been outlined. Furthermore, this chapter also briefly discusses the role of enzymes in the degradation of different plastics by microbes and the future of plastic biodegradation.

Biodegradation of typical plastics and its mechanisms

This review summarizes the mechanisms by which common plastic types are broken down by bacteria, fungi, and other microorganisms in the environment. Despite their chemical stability, many plastics can be degraded — though slowly — with the pace depending on environmental conditions and plastic type. The paper provides a foundation for developing faster biodegradation strategies to reduce plastic pollution.
