The threat of microplastics and microbial degradation potential; a current perspective
AI summary Read the abstract
This review covers the growing threat of microplastics in marine environments, where they enter the food chain and can transfer to humans along with pathogenic organisms, causing various toxic effects. The paper also explores how bacteria and fungi found in ocean environments could be harnessed to biodegrade different types of plastics as a future strategy for reducing microplastic pollution.
Microplastics in marine environments come from various sources, and over the years, their buildup in marine environments suggests an inevitable need for the safe mitigation of plastic pollution. Microplastics are one of the chief and hazardous components of marine pollution, as they are transferred through the food chain to different trophic levels, affecting living organisms. They are also a source of transfer for pathogenic organisms. Upon transfer to humans, several toxic effects can occur. This review aims to assess the accumulation of microplastics in marine environments globally, the threat posed to humans, and the biodegradation potential of bacteria and fungi for future mitigation strategies. The versatility of bacteria and fungi in the biodegradation of different types of plastics has been discussed, with a focus on the microbial majority that has been cultivated in labs from the marine environment. We also propose that the exploration of yet-to-be-cultivated microbial majority can be a way forward for employing future strategies to mitigate microplastics.
