Summary

This research investigated how environmental conditions like humidity, CO2 levels, and light affect enzyme activities in the edible mushroom Hypsizygus marmoreus. Understanding these relationships is crucial for optimizing commercial mushroom cultivation. Impact on everyday life: – Improved mushroom cultivation techniques leading to better quality and yield – More efficient production of nutritious food source – Better understanding of how to control growing conditions for mushroom farming – Potential cost reduction in commercial mushroom production – Enhanced sustainability in agricultural practices

Background

Hypsizygus marmoreus is an important edible mushroom variety in East Asia that requires specific environmental conditions for optimal growth. The cultivation environment is complex, with humidity, CO2 concentration and light requirements varying across different growth stages. Previous studies found that controlling environmental factors like temperature, humidity, light intensity and CO2 concentration could significantly improve biological conversion rates.

Objective

To investigate the effects of environmental factors such as humidity, CO2 and light intensity on degrading enzymes during budding and ripening stages of H. marmoreus, to understand the influence mechanism of environmental factors on mushroom growth and provide guidance for large-scale efficient cultivation.

Results

Xylanase and laccase activities showed significant positive correlation with CO2 concentration and light intensity, while being negatively correlated with humidity during budding stage. CMCase and MnP activities were positively correlated with humidity but negatively correlated with CO2 concentration and light intensity. In mature fruit bodies, xylanase maintained similar correlations while MnP showed positive correlation with humidity and negative correlation with light intensity. β-glucosidase activity was consistently negatively correlated with CO2 and positively correlated with humidity in both growth stages.

Conclusion

Environmental factors significantly influence enzyme activities during H. marmoreus growth, with different enzymes showing varying responses to CO2, humidity and light conditions. These findings emphasize the importance of controlling environmental parameters for optimal mushroom cultivation, as they directly affect growth, development and yield through their impact on enzyme activities.
