Query: NC_002939:805794 Geobacter sulfurreducens PCA, complete genome
Lineage: Geobacter sulfurreducens; Geobacter; Geobacteraceae; Desulfuromonadales; Proteobacteria; Bacteria
General Information: This strain was isolated from surface sediments of a hydrocarbon-contaminated ditch in Norman, Oklahoma, USA. Common metal-reducing bacterium. This organism, similar to what is observed in Geobacter metallireducens, is one of the predominant metal-reducing bacteria found in subsurface communities.
Subject: NC_010424:697187 Candidatus Desulforudis audaxviator MP104C, complete genome
Lineage: Desulforudis audaxviator; Desulforudis; Peptococcaceae; Clostridiales; Firmicutes; Bacteria
General Information: Its genome indicates a motile, sporulating, sulfate-reducing, chemoautotrophic thermophile that can fix its own nitrogen and carbon by using machinery shared with archaea. Candidatus Desulforudis audaxviator is a gram positive sulfate reducing bacteria identified in fracture water from a borehole at a depth of 2.8 km in a South African gold mine. Water from these boreholes is very old (low-biodiversity fracture water), suggesting that these bacteria have been isolated from the Earth's surface for as much as several million years.
