为获得耐Cu2+和耐低pH的硫酸盐还原菌，本研究通过富集培养分离到硫酸盐还原菌，以SO42-2-为考察指标，优化了其生长因子碳源、pH、COD/SO4比值和温度，结果表明：乳酸钠作为2-碳源、pH=7、COD/SO4=1.6、温度30℃为该菌最优生长条件.通过驯化获得能够在Cu2+浓度为90 mg/L、pH=4.5的条件下生长的硫酸盐还原菌，可为硫酸盐还原菌处理含Cu2+酸性矿山废水工艺提供菌株.

In this study, sulfate reducting bacteria was separated by the enrichment culture to obtain sulfate reducting bacteria with the resistance to Cu2+ and low pH. By taking SO 4 2-as the investigating index, growth 2-factors of carbon source, pH, COD/SO 4 ratio and temperature were optimized. The results show that these 2-optimal growth conditions for sulfate reducing bacteria are:sodium lactate as a carbon source, pH=7, COD/SO 4=1.6, and the temperature 30℃. Through the domestication, sulfate reducting bacteria could grow under the conditions of the 90 mg/L of Cu2+ concentration and pH=4.5. Our results may provide the strains for the treatment of acidic mine drainage containing Cu2+.
