摘要：通过对顶头孢霉(Cephalosporium acremonium)FC-01进行诱变选育及特定种子培养基的优化,提高了头孢菌素C的发酵产量。分别采用紫外-氯化锂和钴-60(60Co)γ射线对FC-01进行诱变选育,筛选到高产菌株FC-1-4和FC-4-2,产量较出发菌株分别提高了26%和54.5%。运用Plackett-Burman设计方法和响应面法对种子培养基进行优化,头孢菌素C发酵效价较对照分别提高了34.7%和13.2%,优化后的种子培养基主要成分为玉米浆3.70%、葡萄糖2.62%和硫酸镁0.15%,得到的菌株及相应的种子培养条件已成功应用在160M3工业发酵罐生产中,具有重要的工业生产能力。
The Cephalosporin C fermentation was improved through mutations and optimization of the seed medium. High-producing strains Cephalosporium acremonium FC-1-4 and FC-4-2 were obtained with60 Co irradiation and Uv ＋ LiCl treatment,the production were 26% and 54. 5% higher than that of control.Meanwhile,the optimal seed medium component were 2. 62% glucose,3. 70% corn steep liquor,0. 15%MgSO4via Plackett-Burman and central composite design（ CCD）. The 34. 7% and 13. 2% increase of Cephalosporin C production was achieved with the Cephalosporium acremonium FC-1-4 and FC-4-2 respectively.The obtained high-producing strains and optimal seed medium have crucial industrial utilization in the future.
