| Abstract: | A strain of Bacillus producing soymilk clotting enzyme was isolated from 104 soil samples. After mutagenic treatment and fermentation test, its soymilk clotting enzyme activity could reach 1 6u/ml. The optimum medium consisted of 2 5% wheat bran, 0 5% (NH 4) 2SO 4 , 0 5% (NH 4) 2HPO 4 and 0 05% CaCl 2. |
