里氏木霉 黑曲霉 小麦饲粮酶制剂
本试验对里氏木霉(Trichoderma reesei-xy07)和黑曲霉(Aspergillus niger-Y06)混菌固态发酵的培养条件进行优化,确定了菌株产酶最适的pH值、温度、含水量、碳源、氮源、铵盐及最佳发酵时间等,为小麦饲粮酶制剂生产和应用提供重要的理论基础。%Optimization of culture conditions for enzyme preparation by the solid-state fermentation with the Trichoderma reesei-xy07 and Aspergillus niger-Y06 was carried out in this experiment. The optimal pH value, temperature,concentration of water,carbon source,nitrogen source and fermentation time of cultivation were determined. This study provides important theory basis of the production of wheat dietary enzyme preparation.
