Scientists can genetically tweak oyster mushroom enzymes to make them digest plastic up to three times faster.
Scientists have experimented with modifying the genes responsible for laccase and peroxidase production in Pleurotus ostreatus. By increasing expression levels and stability of these enzymes, fungi can attack polymer chains more efficiently. Laboratory trials show that enhanced strains degrade polyethylene and polyurethane significantly faster than wild-type mushrooms. The modifications do not alter the mushroom’s edible properties but optimize environmental remediation functions. Researchers also observed that these engineered fungi form denser mycelial networks on plastic surfaces. Enzyme engineering allows precise targeting of difficult-to-degrade plastics and offers scalability for industrial applications. The approach demonstrates how biotechnology can augment natural fungal capabilities. Oyster mushrooms become living biofactories for targeted polymer degradation. Controlled experiments ensure ecological safety while maximizing plastic conversion efficiency.
