神农霉素Ⅱ号组分生产菌株的选育

Breeding of production strains of shennongmycin Ⅱ

神农霉素Ⅱ号组分产生菌Z009经紫外线和微波诱变处理,得到D-81菌株,其摇瓶效价是出发菌株Z009的3.46倍.经菌种稳定性检测,D-81菌株遗传稳定性较好.

The shennongmycin Ⅱ -producing strain Z009 was treated with UV and microwave. Finally, a mutant D- 81 was obtained, whose chemical potency is just 3.46 times as much as the original strain. The inheritance stability of strain D - 81 is good.
