摘　　要： 以紫外线为诱变剂,用庆大霉素产生菌JY1-12为出发菌株,选育出性能优良的菌株JY3-5.经正交试验确定其最佳发酵培养基,研究了最佳发酵温度和初始pH值,使其摇瓶效价提高35.1%;30m3灌放大试验,比出发菌株效价提高19.2%. The start strain of JY112 was treated with UVrayirradiation to obtain a strain of micmmonospora purpurea JY35 with high yield gentamich. The culture medium was optimizied for the strain JY35 by L9(34)test, and the effective factors on fermentation was also studied. The fermentation potency of strain JY35 in shaker. the increased by 34.3%, and in 30m3 fermentor its increase was 18.6% as compared with JY112.
