摘要
选用抗菌肽生产菌KJ02为出发菌,对其发酵培养基进行了研究并使用正交设计优化了发酵培养基。优化后的培养基:葡萄糖3%,蛋白胨1%,酵母膏2%,NaCl 0.5%。同时在500 L中式水平上对该培养基的效果进行了试验,发酵液杀菌效价为13651IU/mL。
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.
