Cadmium (Cd) is considered a toxic heavy metal; nevertheless, its toxicity fluctuates for different organisms. Cadmium-tolerant bacteria (CdtB) are diverse and non-phylogenetically related. Because of their ecological importance these bacteria become particularly relevant when pollution occurs and where human health is impacted. The aim of this review is to show the significance, culturable diversity, metabolic detoxification mechanisms of CdtB and their current uses in several bioremediation processes applied to agricultural soils. Further discussion addressed the technological devices and the possible advantages of genetically modified CdtB for diagnostic purposes in the future.
镉（Cd）被认为是一种有毒重金属；然而，其毒性因不同的生物体而有所波动。镉耐受细菌（CdtB）具有多样性，且彼此间没有系统发育关系。由于其生态重要性，当发生污染且人类健康受到影响时，这些细菌就变得尤为相关。本综述旨在展示 CdtB 的重要性、可培养的多样性、代谢解毒机制及其在几种应用于农业土壤的生物修复过程中的当前用途。进一步的讨论涉及到技术设备以及未来用于诊断目的的遗传修饰 CdtB 的可能优势。
