摘要: 采用热诱变处理,结合庆大霉素抗性筛选法筛选,对产抗生素的炭样小单孢菌JXNU-1 进行选育,最终获得抗生素 高产菌株JXNU-1-16-R4。结果显示,其抗生素产率比出发菌株提高了98.53%。

Abstract: Heating mutagenesis effect, combined with gentamicin resistance screening, was used in breeding of prolific Micromonospora carbonacea in antibiotics production from the strain of Micromonospora carbonacea JXNU-1. The overproducing strain JXNU-1-16-R4 was screened with the production of antibiotics is 98.53% more than that of the original strain.

Key words: Micromonospora carbonacea, Heat mutagenesis, Resistance screening
