The heavy metals cadmium (Cd) and chromium (Cr) are extensively used in industry and result in water and soil contamination. The highly toxic Cd(II) and Cr(VI) are the most common soluble forms of Cd and Cr, respectively. They enter the human body through the food chain and drinking water and then cause serious illnesses. Microorganisms can adsorb metals or transform Cd(II) and Cr(VI) into insoluble or less bioavailable forms, and such strategies are applicable in Cd and Cr bioremediation. This review focuses on the highlighting of novel achievements on microbial Cd(II) and Cr(VI) resistance mechanisms and their bioremediation applications. In addition, the knowledge gaps and research perspectives are also discussed in order to build a bridge between the theoretical breakthrough and the resolution of Cd(II) and Cr(VI) contamination problems.
重金属镉（Cd）和铬（Cr）在工业中广泛使用，导致水和土壤污染。剧毒的Cd（II）和Cr（VI）分别是Cd和Cr最常见的可溶形式。它们通过食物链和饮用水进入人体，进而引发严重疾病。微生物可以吸附金属或将Cd（II）和Cr（VI）转化为不溶性或生物有效性较低的形式，这些策略适用于Cd和Cr的生物修复。本综述着重介绍微生物对Cd（II）和Cr（VI）抗性机制及其生物修复应用的新成果。此外，还讨论了知识空白和研究前景，以便在理论突破与解决Cd（II）和Cr（VI）污染问题之间架起一座桥梁。
