Studies with a highly saline uranium-contaminated aquifer sediment demonstrated that the addition of acetate could stimulate the removal of U(VI) from the groundwater. This removal was associated with an enrichment in microorganisms most closely related to Pseudomonas and Desulfosporosinus species.</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/12788780?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Finneran, Kevin T</style></author><author><style face="normal" font="default" size="100%">Johnsen, Claudia V</style></author><author><style face="normal" font="default" size="100%">Lovley, Derek R</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Rhodoferax ferrireducens sp. nov., a psychrotolerant, facultatively anaerobic bacterium that oxidizes acetate with the reduction of Fe(III).</style></title><secondary-title><style face="normal" font="default" size="100%">Int J Syst Evol Microbiol</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Int.

A novel isolate, designated T118(T), was recovered in a medium with lactate as the sole electron donor and Fe(III) as the sole electron acceptor. Cells of T1 18(T) were Gram-negative, motile, short rods with a single polar flagellum. Strain T1 18(T) grew between pH 6.7 and 7.1, with a temperature range of 4-30 degrees C. The optimal growth temperature was 25 degrees C. Electron donors utilized by strain T1 18(T) with Fe(III) as the sole electron acceptor included acetate, lactate, malate, propionate, pyruvate, succinate and benzoate. None of the compounds tested was fermented. Electron acceptors utilized with either acetate or lactate as the electron donor included Fe(III)-NTA (nitrilotriacetic acid), Mn(IV) oxide, nitrate, fumarate and oxygen. Phylogenetic analysis demonstrated that strain T1 18(T) is most closely related to the genus Rhodoferax. Unlike other species in this genus, strain T1 18(T) is not a phototroph and does not ferment fructose. However, phototrophic genes may be present but not expressed under the experimental conditions tested. No Rhodoferax species have been reported to grow via dissimilatory Fe(III) reduction. Based on these physiological and phylogenetic differences, strain T1 18(T) (=ATCC BAA-621(T) = DSM 15236(T)) is proposed as a novel species, Rhodoferax ferrireducens sp. nov.</style></abstract><issue><style face="normal" font="default" size="100%">Pt 3</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/12807184?dopt=Abstract</style></custom1></record></records></xml>
