Query: NC_008344:1899317 Nitrosomonas eutropha C91, complete genome
Lineage: Nitrosomonas eutropha; Nitrosomonas; Nitrosomonadaceae; Nitrosomonadales; Proteobacteria; Bacteria
General Information: Nitrosomonas eutropha C91 was isolated from a sewage disposal plant in Chicago. Ammonia-oxidizing bacterium. This species consists of ammonia-oxidizing bacteria that catalyze the oxidation of ammonia to nitrite and contribute to the global cycling of nitrogen (a process called nitrification). This obligate chemolithoautotroph is studied for that reason.
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.
