摘　　要：重金属污染对人类及其他生物的生存已构成严重威胁,微生物重金属抗性及其抗性基因在重金属污染土壤的生物修复中显示出巨大潜力。当前,来自世界不同国家的科学家对大肠杆菌中的有关重金属抗性菌株进行了研究。研究主要包括对重金属抗性菌株进行筛选与鉴定、基因簇复制、基因调控表达等。笔者就大肠杆菌对重金属的抗性和解毒机理进行介绍,为实现以生物方法治理重金属污染奠定理论基础。Heavy metal pollution poses a serious threat to the survival of human and other living beings. Microbes heavy metal resistance and its resistance genes show great potential in bioremediation of heavy metal contaminated soil. At present, scientists have done a lot of research on the screening and identification of heavy metal resistant strains of Escherichia coli, cloning and expression of gene clusters. In this paper, the mechanism of resistance to heavy metals and detoxification of heavy metals in Escherichia coli is reviewed. To lay a theoretical foundation for the treatment of heavy metal pollution in biological methods.
