摘要
本试验从5份土壤中共筛选出产碱性蛋白酶菌株9株,即SHL-4、SHL-6、SHL-7、SHL-10、SHL-8、SHL-11、SHL-12、SHL-18、SHL-20,其中SHL-4、SHL-6、SHL-7、SHL-10产酶效果较好;采用正交试验设计,初步地确定了菌株SHL-4产酶培养基组分,即蛋白胨0.5%、牛肉膏1.5%。
Nine strains producing alkaline protease were screened out from five soil samples, namely SHL-4,6,7,10,8,11,12,18,20, SHL-4,6,7,10 of whichwith high protease activity. Through an orthogonal test, the producing protease culture medium of the SHL-4 strain was confirmed preliminarily, namely 0.5% of peptone, 1.5% of beef extract.
