| 摘 要： | 目的]筛选出对甲基橙废水具有较好脱色效果的微生物絮凝剂产生菌及不同培养条件对其脱色效果的影响。方法]用分光光度计测定脱色前后甲基橙溶液的吸光度,计算脱色率大小,对比不同培养条件对甲基橙去除率影响。结果]筛选出了1株放线菌F-1-2,以蔗糖为碳源,NaNO3为氮源,在150r/min的恒温震荡器中于30℃培养72h后,发酵液对甲基橙去除率可达68.4%。结论]不同培养条件对菌株的脱色效果影响显著。

| Abstract: | Objective] To screen out a microbial flocculant with good decolorization effect on methyl orange wastewater,and study the effect of different cultural conditions on decolorization effect of methyl orange.Method] Absorbance of methyl orange solution before and after decolorization was determined by spectrophotometer,and the decolorization rate was calculated to compare the effects of different cultural conditions on removal rate of methyl orange.Result]An optimal actinomycete stain(F-1-2) was screened out,and the best cultural condition was as follows:with sucrose as carbon source and NaNO3 as nitrogen source,cultured in constant temperature oscillator at 150 r/min,30℃ for 72 h.Under the optimal condition,the removal rate against methyl orange could reach 68.4%.Conclusion]Different culture conditions have great impact on decolorization effect of strain. |
