异化Fe(Ⅲ)还原及其在污染治理中的作用

Dissimilatory Fe(Ⅲ) Reduction and its Applications in Contaminants Treatment

摘要:

细菌的异化Fe(Ⅲ)还原指以Fe(Ⅲ)为末端电子受体在无氧条件下氧化有机物的产能过程,在生物地球化学循环中起着重要的作用。系统综述了异化Fe(Ⅲ)还原细菌与多种代谢反应相耦联的Fe(Ⅲ)还原过程、还原不溶性Fe(Ⅲ)氧化物的机制,及其与Fe(Ⅲ)还原相关的分子生物学的研究进展。介绍了国内外有关Fe(Ⅲ)还原在环境污染治理中的研究现状及其发展趋势。

Abstract:

Dissimilatory Fe(Ⅲ)reduction is the important process in Biogeochemical cycle.This paper gives a systematic introduction to the types of dissimilatory Fe(Ⅲ)reduction,mechanism of insoluble Fe(Ⅲ)oxidizes reduction and the advances of molecular biology in- volved in Fe(Ⅲ)reduction.The status of the applications of dissimilatory Fe(Ⅲ)reduction in environmental contaminant treatment were also discussed.
