Query: NC_017068:2661419 Selenomonas ruminantium subsp. lactilytica TAM6421, complete
Lineage: Selenomonas ruminantium; Selenomonas; Veillonellaceae; Selenomonadales; Firmicutes; Bacteria
General Information: This organism is a member of the normal flora of the sheep rumen. The genus Selenomonas constitutes a group of motile crescent-shaped bacteria and includes species living in the gastrointestinal tracts of animals, in particular, the Ruminants. Despite being Firmicutes they stain Gram-negative and possess a double bilayer. Cells are crescent or bean-shaped with coiled flagella located on the concave surface with an infolding of the cell membrane behind the flagellar attachment point.
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.
