Query: NC_010338:650054 Caulobacter sp. K31, complete genome
Lineage: Caulobacter; Caulobacter; Caulobacteraceae; Caulobacterales; Proteobacteria; Bacteria
General Information: Caulobacter strain K31 was isolated in an enrichment culture for chlorophenol-tolerant bacteria in groundwater from Karkola, Finland, which percolates through nutrient-poor silt and clay, and is cold (7-8oC), oxygen-deficient, iron-rich, and mildly acidic (pH 6-6.5).
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.
