摘要
利用劣质碳氮源大豆秸秆代替优质碳氮源牛肉膏和蛋白胨,强化微生物脱色偶氮染料活性黑5,采用Miseq高通量测序技术对脱色过程中的微生物群落结构进行分析。研究结果表明,大豆秸秆为唯一碳氮源时,混合菌群对50 mg/L活性黑5溶液的脱色率为51.84%,表明具有较好的脱色效果。Miseq高通量测序分析结果显示,经过大豆秸秆强化作用,鲍特菌属(Bordetella)成为最优势菌种,说明大豆秸秆可以为鲍特菌属(Bordetella)提供良好的生存环境。研究结果为今后利用大豆秸秆强化微生物处理实际染料废水效果提供理论依据。
Poor quality carbon and nitrogen source soybean straw was used to enhance the microbial decolorization of azo dye Reactive Black 5,instead of high quality carbon and nitrogen source beef extract and peptone,and the microbial community structure during decolorization process was analyzed by using Miseq high-throughput sequencing technology.The results showed that when soybean straw was the only carbon and nitrogen source,the decolorization rate of azo dye Reactive Black 5(50 mg/L)by mixed bacteria flora was 51.84%,indicating a better decolorization effect.The results of Miseq high-throughput sequencing analysis showed that after the enhancing effect of soybean straw,Bordetella became the most dominant bacteria,indicating that soybean straw could provide a good living environment for Bordetella.A theoretical basis was provided for the future use of soybean straw to enhance the microbial treatment effect of actual dyeing wastewater.
