Query: NC_012883:104987 Thermococcus sibiricus MM 739, complete genome
Lineage: Thermococcus sibiricus; Thermococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: Thermococcus sibiricus is a hyperthermophilic anaerobic archaeon isolated from a well of the never flooded oil-bearing Jurassic horizon of the high-temperature Samotlor oil reservoir (Western Siberia). The organism is indigenous to the reservoir and survived over geologic time by metabolizing buried organic matter from the original oceanic sediment.
Subject: NC_007964:717590 Nitrobacter hamburgensis X14, complete genome
Lineage: Nitrobacter hamburgensis; Nitrobacter; Bradyrhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Nitrobacter hamburgensis X14 was isolated from soil. Nitrite-oxidizing soil bacterium. Members of this genus are found in marine, freshwater, and terrestrial habitats, often in association with ammonia-oxidizing bacteria. These organisms oxidize nitrite, generated by the oxidation of ammonia, to nitrate and play an important role in the global nitrogen cycle. The enzyme involved in nitrite oxidation, nitrite oxidoreductase, can also reduce nitrate to nitrite in the absence of oxygen, allowing Nitrobacter sp. to grow anaerobically. Nitrobacter hamburgensis is commonly isolated from freshwater, soil, and sewage sludge. This organism has been used in biofilms to remove nitrogen from wastewater.
