摘　　要：采集尾矿坝厌氧污泥,通过微生物培养富集,获得混合SRB菌种。对富集菌种进行梯度驯化,使之能够适应酸法地浸采铀地下水环境。经驯化后,混合SRB耐受温度可低到20℃、pH可低到4、硫酸根质量浓度可高达4g/L、铀质量浓度可高达5mg/L,该研究为SRB应用于酸法采铀地下水的修复提供了必要的基础。Mixed SRB is cultured and accumulated from anaerobic sludge of a mine s tailing.Gradient domestication is taken on mixed SRB to acid groundwater environment,the cultured mixed SRB can tolerate under the conditions of temperature is 20℃,pH is 4,sulphate mass concentration is 4 g/L and uranium mass concentration is 5 mg/L,which can provide the basis for groundwater rehabilitation at in-situ leaching acid uranium mine.
