摘要
以吸水链霉菌NND 5 2菌株为原始菌株 ,利用紫外诱变和LiCl复合处理 ,采用琼脂柱移菌法进行初筛。用清酒酵母作为特异性指示菌 ,经复筛获得一株除莠霉素A高产菌株 ,产量为 980 0 9μg·mL-1 ,比原始菌株提高了 2 2 6倍。
An agar gel transplanting model for mutation pre screening by selective indicator microorganism Saccharomyces sake was built up.Through combined mutation procedure UV+LiCl,take Streptomyces hygroscopicus NND 52 as original strain,a herbimycin A high yield strain was isolated.Its yield increased by 2 26 times,to 980 09 μg·mL -1 .
