微生物与重金属间的相互作用及其应用研究

从多方面阐述了微生物与重金属二者间相互作用，指出微生物在生长代谢过程中能淋滤、吸收和转化重金属，对重金属有一定的抗性和解毒作用；但是，一定浓度的重金属对微生物过程及其种群具有较大的毒性。影响微生物在环境介质中的活动，矿业工程生产工艺已充分利用微生物能淋滤，吸收和转化重金属等特性来处理低品位难浸矿石，环境保护领域也积极利用微生物对重金属的抗性和解毒作用来实现工业废弃物的处理以及被重金属污染土壤的修复。利用微生物的生物量及其活性可以评价环境中不同介质的重金属污染水平。

Interaction between microorganisms and heavy methals and its application

Interactions between microorganisms and heavy metals were expatiated in many ways.Because of their resistance and detoxification to heavy metals,microorganisms are able to leach,absorb and transform heavy metals,which has been actively applied to extract heavy metals from low-rate ore in mine exploitaion.Although heavy metals are toxic to microorganisms population and harmful to its processes,some special microorganisms have been applied to the treatment of industrial waste materials and the remediation of soils polluted by heavy metals.The application of microbiological biomass and activity to evaluating the pollution situation and ecological risk of heavy methals in environment media is also significant.
