摘要 从新疆棉株上分离得到一株细菌ZK ,发酵生产抗病原真菌肽类物质 -捷安肽素。以此株菌作为出发菌株 ,通过紫外线诱变处理获得了高产突变株UV14 6 ,在摇瓶试验中 ,该变异株产捷安肽素的量高于亲株。 A strain of bacterium named ZK was isolated from cotton plant in Xinjiang. Its metabolin is antifungal peptide named Jiean-peptide. Using strain ZK as starting strain, after UV irradiation, a high Jiean-peptide yielding mutant UV146 was obtained. Its fermentation production are higher than starting strain.
