酒精废液降解菌Q5的化学诱变

目的：筛选出一些酒精废液的降解菌。方法：使用亚硝基胍（NTG）、亚硝基甲基脲（NMU）等对酒精废液降解菌Q5进行诱变。结果：在无机盐选择培养基上生长菌株有36株,再经5次传代试验仅有8株能稳定传代,最后筛选出以酒精废液为碳源的性能较好的突变菌株Q58。该突变菌株Q58对酒精废液的降解率比出发菌株高0.65%;对酒精废液的降解时间比出发菌株缩短12h。

Study on Alcohol Wastewater Degradation Bacterial Q5 by Chemical Induced Mutations

Objective:Some alcohol wastewater degradation bacterial were screened.Method:Q5 was induced by NTG and NMU.Result:Thirty six target strains had been got on the selective culture medium,in which eight strains of them have stable heredity through five times heredity experiments.Mutation Q58 was obtained for its better degradation function.Q58 can use alcohol wastewater as only carbon.Compared with the original Q5,mutation Q58 could improve alcohol wastewater degradation rate 0.65% and the degradation time can be shorten 12 hours.
