摘要
本实验根据对融合子Sr-1菌株摇瓶培养基组成及发酵条件单因素优化基础上,利用响应面法获得最佳的培养基配方为葡萄糖33g/L、糊精7.7g/L、胰蛋白胨26g/L、酵母浸粉8.2g/L、初始pH7.0、最佳接种龄28h,发酵周期72h。
In this study, on the basis of shaking culture medium of fusant Sr-1 and single-factor test results of fermentation conditions, the optimum fermentation medium compositions and conditions of fusant Sr-1 for natamycin production were obtained by means of response surface methodology, which were as follows： glucose 33 g/L, dextrin 7.7 g/L, tryptone 26 g/L, yeast extract powder 8.2 g/L, initial pH 7.0, cell age of fermentation strain 28 h and fermentation time 72 h.
