| Abstract: | The fermentation medium of a cecropin-produntion strain K J02 were studied and optimized by orthogonal test. The optimal components for fermentation medium were glucose 3%, peptone 1%, yeast extract2% and NaC10.5%. With the optimal medium, the eeeropin efficiency in 500 L fermentator was up to 13651 IU/mL. |
