摘要
通过对两株麦迪霉素产生菌突变株N-2、Bm-7的稳定性试验结果表明,N-2菌株于4℃条件下,其母斜面保存1个月左右,子斜面保存5天对发酵无影响,第二代子斜面的生产能力亦无变化。而Bm-7菌株是不稳定的。
Stability of midecamycin producing strains mutants N-2 and Bm-7 were tested. Results showed that mutant N-2 was stable when 30 days was allowed for firstgeneration slant and 5 days for second generation slant at 4℃, Mutant Bm-7 was foundunstble.
