Oyster mushrooms secrete more plastic-degrading enzymes when their environment is slightly acidic, around pH 5.5 to 6.5.
The chemical environment of the substrate has a strong impact on fungal metabolism. Slightly acidic pH conditions between 5.5 and 6.5 optimize laccase and peroxidase activity, enhancing plastic polymer breakdown. Alkaline conditions reduce enzymatic stability and slow hyphal growth, while extreme acidity can inhibit metabolism or kill the fungus. Experiments adjusting substrate pH have demonstrated that oyster mushrooms adjust their enzyme secretion dynamically in response to chemical cues. The pH balance also affects nutrient solubility and substrate integrity, indirectly influencing degradation rates. By monitoring and adjusting pH, researchers can maintain consistent degradation performance. Oyster mushrooms exhibit biochemical adaptability, modulating enzyme output to maximize resource utilization. Optimal pH management is essential for scaling fungal plastic remediation projects. Understanding these interactions allows precise tuning of environmental conditions to improve outcomes.
