| Abstract: | The conditions of protease fermentation of the wildtype strain Bacillus sp. HX-318 were studied. The results indicated that the optimal medium for protease production by strain HX-318 was composed of soluble starch 10g/L, soy bean meal 20, wheat bran 20, CaCO3 5.0, KH2PO4 0.3, Na2HPO4· 12H2O 4.0..When strain HX-318 was grown at 34℃ for 48h, the yield of protease 2300U/mL culture solution was obtained. This culture solution showed a strong unhairing activity. |
