ClearPleurotus ostreatus-Mediated Bioremediation of PolylacticAcid Microplastics: Unveilinga Sustainable Solution
Researchers found that the edible white-rot fungus Pleurotus ostreatus degrades polylactic acid microplastics within 30 days through laccase-driven oxidative scission of ester bonds, producing new carbonyl, carboxyl, and hydroxyl surface groups while increasing crystallinity as enzymatic attack preferentially targets amorphous polymer domains.
Is Laccase derived from Pleurotus ostreatus effective in microplastic degradation? A critical review of current progress, challenges, and future prospects
This review explores using the enzyme laccase from oyster mushrooms as a natural way to break down persistent plastics like polyethylene, polystyrene, and PVC. While promising, the approach currently requires improvements through genetic engineering and optimized growing conditions to make it practical at scale. If successful, this biological approach could offer an environmentally friendly alternative to managing the growing microplastics problem.

This study demonstrated that the enzyme laccase can degrade three types of microplastics — polyethylene (PE), PET, and PLA — by breaking apart polymer chains and transforming surface chemical groups, with biodegradable PLA showing the highest degradation efficiency. The mechanistic insights into how reactive oxygen species and electron transfer drive enzymatic degradation provide a foundation for developing enzyme-based treatments to remove microplastics from water and soil.
Fungal Enzymes Involved in Plastics Biodegradation
Researchers reviewed the current literature on fungal enzymes capable of degrading various types of plastic polymers.

Myco-remediation of plastic pollution: current knowledge and future prospects
Researchers reviewed the growing body of evidence showing that fungi can break down common plastics — including polyethylene, polystyrene, and polypropylene — by secreting specialized enzymes that attack and mineralize plastic polymers, with many effective species coming from the Aspergillus and Penicillium families. The review calls for metagenomic approaches to discover more plastic-degrading fungi and develop them into practical bioremediation tools.
