(Submitter supplied) G. uraniireducens was isolated from a subsurface site in Rifle, CO undergoing in situ uranium bioremediation. Sediments from the Rifle site were heat-sterilized, amended with acetate to simulate in situ bioremediation conditions, and inoculated with G. uraniireducens. Gene transcript abundance in these cells using sediment Fe(III) and Mn(IV) oxides as the electron acceptor were compared with transcript levels in cells grown with fumarate as the electron acceptor. more...

(Submitter supplied) Previous analysis of gene transcript levels of Geobacter species in groundwater during in situ bioremediation of a uranium-contaminated aquifer detected expression of genes encoding superoxide dismutase (sodA) and cytochrome d ubiquinol oxidase (cydA), proteins known to be involved in the response to oxidative stress in other microorganisms. In order to further elucidate gene expression patterns that could be attributed to oxygen exposure, G. more...

(Submitter supplied) Geobacteraceae transfer electrons from a donor such as acetate to an electron acceptor such as Fe(III) or U(VI). Geobacter uraniireducens is found in uranium-contaminated sites and plays an important role in in situ bioremediation. In this experiment, gene expression was compared between G. uraniireducens cultures grown in sediments from a uranium contaminated site amended with acetate and cultures grown in acetate/fumarate medium. more...
