摘　　要：在米曲霉和黑曲霉混合制曲的曲料中添加促生长物质进行试验,研究其对曲料蛋白酶活力和孢子数的影响。确定了促生长物质的配方结果为:蔗糖7%,酪蛋白胨1%,脲7%;复合无机盐的配方为CuSO4·5H2O0.15%,FeSO4 0.20%,MgSO40.10%,K2HPO40.05%,MnCl2 0.15%。Through adding some urging growth materials to koji, which mixed by Aspergillus oryzae and Aspergillus niger , this paper studied effect of it on spore number and protease activity. It confirmed the formula of urging growth materials is cane sugar 7%, casein peptone 1%, urea 7%; the prescription of the inorganic salts is CuSO4· 5H2O 0.15%, FeSO4 0.20%, MgSO4 0.10%, K2HPO4 0.05%, MnCl2 0.15%.
