Oyster mushrooms create mycelial biofilms on plastic surfaces, which helps them break down plastics more efficiently.
Scanning electron microscopy reveals that oyster mushroom hyphae can create dense biofilms on the surfaces of plastics. These biofilms concentrate fungal enzymes directly at the plastic interface, enhancing degradation rates. The hyphal mats trap moisture and stabilize the substrate, creating a microenvironment conducive to enzymatic action. Over weeks, the biofilm slowly erodes the polymer chains while also supporting fungal nutrient uptake. This targeted approach is more efficient than random colonization of surrounding substrate. Environmental factors such as humidity, light, and temperature strongly influence biofilm density and effectiveness. Researchers suggest that biofilm formation is a crucial mechanism behind the surprising plastic-eating capabilities of these fungi. This adaptation demonstrates how structural organization can amplify biochemical processes. Oyster mushrooms use architecture and chemistry to attack even stubborn synthetic materials.
