微生物作用下铁(Ⅲ)对有机污染物的氧化

Organic contaminants′ bio-degradation with Fe(Ⅲ).

一些铁还原菌能够以 Fe( )为唯一的电子受体 ,将有机污染物氧化成二氧化碳。利用铁还原菌的这一性能 ,可以开发厌氧生物修复技术 ,原位净化被有机物污染的环境。本文对铁还原菌及其作用机理、以及与铁还原相藕联的有机物降解及其在生物修复中的潜在作用作了综述。

Some ferric reducing microorganisms can oxidize some contaminants to carbon dioxide using Fe(Ⅲ) as sole electron acceptor. With these microorganisms, biological remedial technology can be developed to deal with the polluted environment in situ. In this article, the ferric microorganisms, dissimilatory Fe(Ⅲ) reduction, contaminants′ degradation with Fe(Ⅲ) reducing and its potential use in bioremedy were reviewed.
