Query: NC_004757:427483 Nitrosomonas europaea ATCC 19718, complete genome

Lineage: Nitrosomonas europaea; Nitrosomonas; Nitrosomonadaceae; Nitrosomonadales; Proteobacteria; Bacteria

General Information: Ammonia-oxidizing bacterium. This organism is an obligate chemo-lithoautotroph as it only uses ammonia and carbon dioxide and mineral salts for growth, and is an important part of the global biogeochemical nitrogen cycle. It can derive all energy requirements from the oxidation of ammonia to nitrate, driving global nitrogen from the reduced insoluble form to the oxidized and potentially gaseous form (including NO and NO2 which are greenhouse gases). The energy derived from ammonia oxidation is in turn used to drive carbon fixation. This bacterium also provides plants with a readily available form of nitrogen, is important in wastewater treatment, and may be involved in bioremediation of sites contaminated with toxic compounds.

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.
