The removal and recovery of heavy metals from a coal pile runoff water using a mixture of multiple metal-tolerant bacterial strains of ATCC 55673, and ATCC 55674 and a Pseudomonas sp. was investigated. The analysis of elemental composition of metal precipitates recovered from the bacterial biomass by transmission electron microscopy andenergy dispersive X-ray analysis revealed the presence of metals originally present in the wastewater. In addition, analysis of metals in culture supernatant and bacterial biomass by inductively coupled plasma emission spectroscopy (ICP-ES) indicated a removal range of 82-100% and a recovery of 15-58% of metals from the wastewater and bacterial biomass, respectively.
研究了使用ATCC 55673、ATCC 55674的多种耐金属细菌菌株与一种假单胞菌属细菌的混合物，从煤堆径流水中去除和回收重金属的情况。通过透射电子显微镜和能量色散X射线分析对从细菌生物质中回收的金属沉淀物的元素组成进行分析，结果表明废水中原本存在的金属也存在其中。此外，通过电感耦合等离子体发射光谱法（ICP-ES）对培养上清液和细菌生物质中的金属进行分析，结果表明从废水中去除金属的范围为82%-100%，从细菌生物质中回收金属的比例为15%-58%。
