Fe(III)的微生物异化还原

异化Fe(III)还原微生物是厌氧环境中广泛存在的一类主要微生物类群,它们的共同特征是可以利用Fe(III)作为末端电子受体而获能。异化Fe(III)还原微生物具有强大的代谢功能,可还原许多有毒重金属包括一些放射性核素,还可降解利用许多有机污染物,在污染环境的生物修复中具有重要的应用价值。本文对异化Fe(III)还原微生物的分布、分类,代谢功能多样性以及异化Fe(III)还原的意义做了评述,旨在加强相关领域的研究人员对此的了解和重视,通过学科的交叉和合作加快我国在这一领域的研究。

Dissimilatory Fe(III) Reduction by Microorganisms

Dissimilatory Fe(III) reducing microorganisms are dominant groups widely present in variety anaerobic environments, which share the common features with the ability to use Fe(III) as the terminal electron acceptor to gain energy. It has been found this multifunctional groups of microorganisms evolved with diverse metabolic ability reducing a variety of toxic heavy metals including some radioactive nuclear, degrading and utilizing a broad range of organic pollutants and showed an important value in the bioremediation of contaminated environment. Here the distribution, classification and metabolic diversity of dissimilatory Fe(III) reducing microorganisms and related environmental relevancies were reviewed in this paper, which aimed to attract more attentions of the related researchers and to accelerate the domestic researches in this field by the cooperation of different disciplines.
