Oyster mushrooms can detect plastic using chemical signals and direct their growth to digest it more effectively.
Research has found that oyster mushrooms secrete small signaling molecules that detect the presence of synthetic polymers in their environment. These chemical cues trigger localized growth of hyphae toward plastic fragments. Once the fungus reaches the plastic, enzyme secretion intensifies at the contact site, accelerating breakdown. This behavior mirrors how fungi detect and metabolize natural lignin or cellulose, repurposed for artificial materials. Laboratory observations show directed mycelial growth forming dense mats on plastic surfaces, optimizing degradation efficiency. Environmental factors such as moisture, pH, and temperature influence chemical signal propagation. The chemical-guided approach allows the fungus to focus energy where it is most needed. This discovery underscores the evolutionary flexibility of fungi in exploiting unconventional substrates. Oyster mushrooms effectively use a combination of chemical intelligence and enzymatic power to tackle persistent pollutants.
