英文摘要：

Microbial dissimilatory Fe（Ⅲ）-reduction is an important biological and geochemical process.Various mechanisms of microbial dissimilatory F（eⅢ）reduction and its roles on environmental remediation were reviewed,including biodegradation on polycyclic aromatic hydrocarbons,chlorinated organic compounds,and its role on migration and transformation of some heavy metals.
