	abstract = {<p>Microbial oxidation of elemental sulfur with an electrode serving as the electron acceptor is of interest because this may play an important role in the recovery of electrons from sulfidic wastes and for current production in marine benthic microbial fuel cells. Enrichments initiated with a marine sediment inoculum, with elemental sulfur as the electron donor and a positively poised (+300 mV versus Ag/AgCl) anode as the electron acceptor, yielded an anode biofilm with a diversity of micro-organisms, including Thiobacillus, Sulfurimonas, Pseudomonas, Clostridium and Desulfuromonas species. Further enrichment of the anode biofilm inoculum in medium with elemental sulfur as the electron donor and Fe(III) oxide as the electron acceptor, followed by isolation in solidified sulfur/Fe(III) medium yielded a strain of Desulfuromonas, designated strain TZ1. Strain TZ1 effectively oxidized elemental sulfur to sulfate with an anode serving as the sole electron acceptor, at rates faster than Desulfobulbus propionicus, the only other organism in pure culture previously shown to oxidize S{\textdegree} with current production. The abundance of Desulfuromonas species enriched on the anodes of marine benthic fuel cells has previously been interpreted as acetate oxidation driving current production, but the results presented here suggest that sulfur-driven current production is a likely alternative.</p>},

	abstract = {The sequences of five conserved genes, in addition to the 16S rRNA gene, were investigated in 30 members of the Geobacteraceae fam. nov. All members of the Geobacteraceae examined contained nifD, suggesting that they are capable of nitrogen fixation, which may explain their ability to compete effectively in nitrogen-poor subsurface environments undergoing remediation for petroleum or metal contamination. The phylogenies predicted from rpoB, gyrB, fusA, recA and nifD were generally in agreement with the phylogeny predicted from 16S rRNA gene sequences. Furthermore, phylogenetic analysis of concatemers constructed from all five protein-coding genes corresponded closely with the 16S rRNA gene-based phylogeny. This study demonstrated that the Geobacteraceae is a phylogenetically coherent family within the delta-subclass of the Proteobacteria that is composed of three distinct phylogenetic clusters: Geobacter, Desulfuromonas and Desulfuromusa. The sequence data provided here will make it possible to discriminate better between physiologically distinct members of the Geobacteraceae, such as Pelobacter propionicus and Geobacter species, in geobacteraceae-dominated microbial communities and greatly expands the potential to identify geobacteraceae sequences in libraries of environmental genomic DNA.},
