Acidiphilium cryptum JF-5

Acidiphilium cryptum (strain JF-5) is an acidophilic dissimilatory iron-reducing bacterium (DIRB) of the alpha subdivision of the Proteobacteria. This bacteria is detected in a variety of extreme low pH, radionuclide- and heavy-metal contaminated habitats where Fe(III) reduction is taking place, and may represent a significant proportion of metal-transforming organisms in these environments. Strain JF-5 serves as a model organism for facultative iron-respiring Alphaproteobacterium. It utilizes glucose as an electron donor with the concomitant reduction of soluble and solid-phase Fe(III). Major findings for this bacterium are a novel outer-membrane cytochrome c involved in iron respiration and a Cr(VI) reductase enzyme. (EBI Integr8)
