A Single Bacterium Capable of Oxidation and Reduction of Iron at Circumneutral pH
Shingo Kato, Moriya Ohkuma
Abstract
sp. strain MIZ03, capable of both Fe(II) oxidation and Fe(III) reduction at circumneutral pH, and we report its physiological characteristics and complete genome sequence. The unexpected capability of this bacterium provides novel insights into the Fe cycle in the environment. Moreover, this bacterium will help to better understand the molecular mechanisms of microbial Fe redox cycling as a model organism.
