一株矿化沉淀重金属铅离子及还原六价铬离子的细菌及其应用
摘要：
本发明提供一株矿化沉淀重金属铅离子及还原六价铬离子的细菌及其应用，属于生物技术领域。该细菌分类命名为苏云金芽孢杆菌（Bacillus thuringiensis）HM-311株，保藏编号为：GDMCC NO：60592。HM-311株具有矿化沉淀重金属铅离子及还原六价铬离子的能力，可用于重金属污染治理。该菌株对铅离子的最高耐受浓度为2100 mg/L，对六价铬离子的最高耐受浓度为600 mg/L。在含有1500mg/L铅离子的培养基中发酵培养两天，可去除培养基中97%的铅离子；在含有100 mg/LCr6+的培养基中发酵培养两天，可还原培养基中70%的六价铬离子离子。
摘要（英）：

The invention provides a bacterium capable of mineralizing and precipitating heavy metal lead ions and reducing hexavalent chromium ions and application of the bacterium, and belongs to the field of biology. The bacterium is classified to be named as a bacillus thuringiensis HM-311 strain, and the preservation number is GDMCC NO: 60592. The HM-311 strain has the capability of mineralizing and precipitating the heavy metal lead ions and reducing the hexavalent chromium ions, and can be used for the treatment of heavy metal pollution. The highest tolerance concentration of the strain on the leadions is 2100 mg/L, and the highest tolerance concentration of the strain on the hexavalent chromium ions is 600 mg/L. Fermentation culture is performed in a culture medium containing 1500 mg/L lead ions for two days, so that 97% of the lead ions in the culture medium can be removed; fermentation culture is performed in a culture medium containing 100 mg/L Cr<6+> for two days, so that 70% of the hexavalent chromium ions in the culture medium can be reduced.
