Research Progress on the Application and Interaction Mechanism between Specific Microorganisms and Heavy Metals in Soil

  • 摘要: 随着经济的发展,矿产资源的开采和利用程度越来越高,一方面发现有地表露头矿床的几率越来越小,另一方面其造成的重金属污染严重危害环境和人类健康。自然界中的微生物与扩散到环境中的重金属会产生相互作用,具有这种特异性的细菌既可应用于指示隐伏金属矿床,亦可应用于重金属污染生物修复。本文从特异性微生物与重金属相互作用微观机制、微生物找矿、重金属污染土壤的微生物修复三个方面,对其研究现状和进展进行了评述,重点对特异性微生物与重金属离子发生的吸附、累积与转化过程,微生物改变重金属元素分布、赋存状态和毒性作用机理,蜡样芽孢杆菌(Bacillus cereus)与金的作用机制及其在寻找隐伏金矿的应用潜力,特异性微生物通过代谢产物吸附去除土壤中重金属元素及其辅助植物修复重金属污染等方面进行了介绍和阐述。

     

    Abstract: Economic development requires exploration and exploitation of mineral resources. It is difficult to find surface outcrop deposits, which will cause soil pollution by heavy metals that is a severe hazard to the environment and human health. Microorganisms in nature interact with heavy metals in air. Microorganisms with this specificity can be applied to metal prospect exploration and environmental bioremediation of heavy metal pollution. Interaction mechanisms between specific microorganisms and heavy metals and its application to exploration and environmental bioremediation of heavy metal pollution have been reviewed. The focus of this paper is on the adsorption, accumulation and transformation process between specific microorganisms and heavy metal ions, as well as the mechanism of microbial organisms changing heavy metal distribution, occurrence and toxicity. The interaction mechanism between Bacillus cereus and gold and its application potential to find concealed gold deposits were reviewed. Removal of heavy metals in the soil by the specific microorganism through the adsorption of metabolites and assisting plants to repair heavy metal pollution were introduced and elaborated upon.
