摘　　要：对米曲霉产胞外脂肪酶的培养条件进行了优化。筛选出麦芽糖为最佳碳源,蛋白胨为最佳氮源,平平加O为最佳的表面活性剂。该菌株产脂肪酶的最适培养条件为:麦芽糖0 5 % ,蛋白胨0 5 % ,橄榄油1 0 % ,平平加O 0 0 32 % ,发酵液初始pH值为6。The extracellular lipase produced by the fungus Aspergillus oryzae was studied in this paper. Optimum conditions of lipase activity were determined The optimal lipase producing conditions of Aspergillus oryzae are as follows: maltose 0 5%, peptone 0 5%, olive oil 1 0%, Peregal O 0 032%, and the beginning pH of the culture medium is 6 0
