[Interaction between microorganisms and heavy metals and its application].

Abstract

Interactions between microorganisms and heavy metals were expatriated 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 exploitation. 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 metals in environment media is also significant.
