Biodegradation of microplastics: Advancement in the strategic approaches towards prevention of its accumulation and harmful effects
AI summary Read the abstract
This review assessed advances in strategic approaches to microplastic biodegradation, covering microbial enzymes, biofilm-mediated degradation, and conditions that enhance breakdown rates, with the goal of identifying practical paths to reducing environmental microplastic accumulation.
Microplastics (MPs) are plastic particles in a size ranging from 1 mm to 5 mm in diameter, and are formed by the breakdown of plastics from different sources. They are emerging environmental pollutants, and pose a great threat to living organisms. Improper disposal, inadequate recycling, and excessive use of plastic led to the accumulation of MP in the environment. The degradation of MP can be done either biotically or abiotically. In view of that, this article discusses the molecular mechanisms that involve bacteria, fungi, and enzymes to degrade the MP polymers as the primary objective. As per as abiotic degradation is concerned, two different modes of MP degradation were discussed in order to justify the effectiveness of biotic degradation. Finally, this review is concluded with the challenges and future perspectives of MP biodegradation based on the existing research gaps. The main objective of this article is to provide the readers with clear insight, and ideas about the recent advancements in MP biodegradation.
