Microbial degradation of plastics: Biofilms and degradation pathways
Summary
This review covers how microorganisms form biofilms on plastic surfaces in soils and water, and how these communities gradually break plastics down through enzymatic activity. Microbial plastic degradation is still slow and incomplete, but understanding the process is key to developing biological plastic cleanup strategies.
Plastics are recalcitrant polymers released in the environment through unpredicted use leading to accumulation and increased water and soil pollution. Transportation of these recalcitrant polymers in agricultural soil, sediment, and water has been causing concerns for environmentalists. Biofilm community adhered on plastic polymers have a significant contribution in their degradation as they warrant bioavailability of substrates, sharing of metabolites and increased cell viability thereby accelerating biodegradation. Metabolic enzymes of the microbes can be exploited as a potent tool for polymer degradation. However very little or Chapter contents Introduction ..

A review on microbial-biofilm mediated mechanisms in marine microplastics degradation
This review examines how microbial biofilms form on microplastics in marine environments and their potential role in degrading these persistent pollutants. Researchers found that plastic-associated biofilm communities are diverse and influenced by factors such as polymer type, particle size, and seasonal conditions. The study identifies knowledge gaps in understanding how bacterial and fungal communities on microplastics may contribute to their breakdown in ocean environments.
Microplastic accumulation in soils: Unlocking the mechanism and biodegradation pathway
Researchers reviewed how microplastics accumulate in soil and break down biologically, finding that certain microorganisms can form biofilms on plastic surfaces and use enzymes to slowly degrade the polymers — though conditions like pH, temperature, and moisture must be optimized and new plastic-degrading microbes need to be identified before this approach can be widely applied.
[Interaction between microplastics and microorganisms in soil environment: a review].
This review examines how microplastics alter soil microbial community structure and diversity, and how microorganisms in turn colonize plastic surfaces and degrade them through extracellular enzymes — with degradation efficiency dependent on polymer properties and environmental conditions.
