摘要
用紫外线 ,紫外线加氯化锂 (Li Cl)、吖啶橙 3种诱变方式对阿扎霉素 (Azalomycin) B产生菌 Strepto-myces hygroscopicus NND- 52菌株进行诱变处理 ,确定了它们的最佳诱变剂量 ,获得了数株 Azalomycin B产量较出发菌株提高 3倍以上的高产菌株 ,编号 Al3的菌株摇瓶产量达 110 0 mg/ L,且传代稳定。经过对 3种诱变方式的比校 ,发现后两种诱变方式对产量的提高更为有效。
Streptomyces hygroscopicus NND 52 producing Azalomycin B was treated with UV,UV+LiCl,acridine orange,the best treatment dose was determined. The yields of several strains which were obtained were more than three times thaat ofCK, and the yield of strain A13 was 1100mg/L,they were stable.Through comparing the treating methods, it was shown that the later two methods were more effective
