| Abstract: | Produced nattokinase in liquid fermentation of Bacillus natto I. Screened the ingredient of culturemedium-carbon source, nitrogen source, the proportion of carbon source and nitrogen source and the concentration of four kinds of salts.The results showed: the optimum culture medium is saccharose 3%, peptone 2%,KH2PO4 0.1%, K2HPO4 0.25%, MgSO4 0.05%, CaCl2 0.01%. |
| Keywords: | Bacillus natto Nattokinase liquid fermentation |
