- Abstract
[Objective] The study aims to discuss the effects of metal ions on the activity of Pleurotus ostreatus and Pleurotus eryngii cellulose. [ Method 0.5 mmol/L FeSO4, CuSO4, MnSO4 and ZnSO4 solutions were added to the basal culture media containing silkworm excrement and rice husk, and the effects of metal ions on activity of FPA and Cx enzyme produced by P. ostreatus and P. eryngii were analyzed. [Result] The addition of Zn2+ and Mn2+ to the basal culture media containing silkworm excrement and rice husk was beneficial to the improvement of the activity of FPA and Cx enzyme produced by P. ostreatus and P. eryngii, while the addition of Fe2+ and Cu2+ inhibited the activity of the cellulase. [Conclusion] The research could provide theoretical references tor improvement of utilization rate of cellulase in silkworm excrement and rice husk.
