The invention discloses a Basophilic Cupriavidus alkaliphilus strain used for highly efficiently removing cadmium pollution. The strain is preserved in China General Microbiological Culture Collection Center on March 29, 2016 with the preservation number of 12319, and is named as Basophilic Cupriavidus alkaliphilus strain LYTTJ. The high-concentration cadmium-resistant strain has good heavy metal resistance, and the cadmium resisting concentration reaches 3000 mg/L. A result of experiments using the strain to treat cadmium polluted water shows that the cadmium removal rate of sewage with the cadmium concentration of 1000 mg/L or less is 100%, so discharge standards are completely reached, and the Basophilic Cupriavidus alkaliphilus strain has great social and economic values. 本发明公开了1、种高效去除镉污染的嗜碱贪铜菌该菌种于2016年3月29日保藏于中国微生物菌种保藏管理委员会普通微生物中心，保藏编号为12319，命名为Cupriavidusalkaliphilus strain LYTTJ。本发明的有益效果：本发明的高浓度耐镉菌株具有良好的重金属抗性，镉耐受浓度达3000mg/L。使用该菌株处理镉污染水实验，可以将污水中镉离子浓度由1000mg/L及以下，其去除率为100％，完全达到排放标准，具有重大的社会和经济价值。
