摘要
通过单因素(温度、豆粕含量、发酵时间)试验和3因素3水平正交试验,以蛋白酶活为测定指标,对米曲霉固态发酵豆粕产蛋白酶条件进行研究,结果表明:米曲霉固态发酵豆粕产蛋白酶最优条件是发酵温度30℃,发酵时间66 h,豆粕含量93%,此条件下的酶活为572.85 U/g。
In the paper,taking activity of protease as a index conditions of producing protease by solid state fermentation of soybean with aspergillus oryzae by single-factor test（temperature,content of soy bean,formentation time）and orthogonal test（lq33）were studied.The results showed that the opimun conditions were：fermentation temperature 30 ℃,fermentation time 66 h,content of soybean 93%,under these conditions,the activity of protease was 572.85 U/g.
