| 摘 要： | 以粮油加工副产品为原料，经黑曲霉、米曲霉混合固态发酵，制备了有较高酶活和较全酶系的饲用复合酶制剂．发酵物料中m(麸皮)：m(豆粕)=4：6，m(水)：m(干料)＝0．8：1，w(Zn^2 )=0．2％和w(Mg^2 )＝0．02％能提高蛋白酶的活力，45℃烘干发酵料，各种酶活损失最小．

| Abstract: | : Feed multienzyme preparation containing many kinds of enzymes from byproducts of grain-processing was reported.it was fermented by Aspergillus niger and Aspergillus oryzae in mixed-culture solid state.The ratio of wheat bran:beancake in culture medium was 4^6,and the ratio of water:dried medium was 0. 8:1.0, w (Zn2 + ) = 0. 2 % and w (Mg2 + ) = 0. 02 % could enhance the acidic protease. The fermented medium was dried at 45 twith the lowest lose of enzyme activity. |
