重金属污染物的微生物修复策略

Microbial Remediation Strategies for Heavy Metal Contaminants

随着我国工业进程的不断加快,重金属污染已成为制约我国经济建设和影响居民健康的主要因素。对重金属污染场地进行科学高效地防治和治理是实现生态环境可持续发展,保障人类生命健康的重要途径。相比传统的化学法和物理法,微生物具有可培养性强、操作简单、环境友好等特点,微生物修复策略被认为是目前重金属污染场地的修复过程中最有潜力的技术。从重金属对微生物的影响和微生物对重金属胁迫的响应方式两个方面进行论述,以为微生物修复技术的规模化应用提供思路及理论基础。

With the continuous acceleration of China’s industrial process,heavy metal pollution has become the main factor restricting China’s economic construction and affecting residents’health.Scientific and efficient prevention and control of heavy metal contaminated sites is the main factor in achieving sustainable development of the ecological environment and ensuring human health.Compared with traditional chemical and physical methods,microbial remediation strategy is considered as the most potential technology in the remediation process of heavy metal contaminated sites due to its strong culturability,simple operation,environmental friendly.In this paper,the effects of heavy metals on microorganisms and the response ways of microorganisms to heavy metal stress were discussed to provide ideas and theoretical basis for the large-scale application of microbial remediation technology.
