摘　　要：采用单因素和正交设计实验,从初始pH、转化时间、接种量及转化温度探讨了鞘细菌转化二价锰离子的特性。研究结果表明,鞘细菌对二价锰离子的最佳转化条件为:初始pH 7.0,转化时间60 h,接种量3%,转化温度27℃。在此条件下,鞘细菌对二价锰离子的转化率可达93.83%。为今后管道疏通及生物除锰等环境治理方面提供一定的理论依据。The conversion characteristics of divalent manganese ions from the initial pH,conversion time,inoculation amount and conversion temperature were investigated by using single facter and orthogonal design experiments.The results showed that the optimum conversion conditions for manganese ions were as follows:initial pH was 7.0,time was 60 h,inoculation amount was 3%,temperature was 27℃.Under these conditions,the conversion rate could reach 93.83%.The study can provide a certain theoretical foundation for the future pipeline dredging and the environmental management of the biological and manganese removal.
