Query: NC_009486:155651 Thermotoga petrophila RKU-1 chromosome, complete genome
Lineage: Thermotoga petrophila; Thermotoga; Thermotogaceae; Thermotogales; Thermotogae; Bacteria
General Information: Thermotoga petrophila strain RKU-1 is an anaerobic thermophile, isolated from the production waters of the Kubiki oil reservoir in Niigata, Japan. This organism, a member of the Thermotogales, has the characteristic morphology of one or more cells contained in a sheath-like envelope which extends beyond the cell wall. Preliminary sequencing of Thermotogales genomes has identified extensive horizontal gene transfer between these organisms and the Archaea.
Subject: NC_010424:1563033 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.
