Furthermore, a mutation in rpoS decreased the rate of reduction of insoluble Fe(III) but not of soluble forms of iron. This study suggests that RpoS plays a role in regulating metabolism of Geobacter under suboptimal conditions in subsurface environments.}, keywords = {Adaptation, Physiological, Bacterial Proteins, Base Sequence, Ferric Compounds, Gene Expression Regulation, Bacterial, Genes, Bacterial, Geobacter, Molecular Sequence Data, Mutation, Oxidation-Reduction, Oxidative Stress, Sigma Factor, Transcription Initiation Site}, issn = {0021-9193}, doi = {10.1128/JB.186.16.5543-5546.2004}, author = {N{\'u}{\~n}ez, Cinthia and Adams, Lorrie and Childers, Susan and Lovley, Derek R} }
