Query: NC_018664:1 Clostridium acidurici 9a chromosome, complete genome
Lineage: Gottschalkia acidurici; Gottschalkia; ; Clostridiales; Firmicutes; Bacteria
General Information: Clostridium acidiurici is an obligate anaerobic Gram-positive bacterium that is motile and spore-forming. It can be isolated from almost every soil but can also be found in the intestinal tract of birds. It is able to use purines like uric acid as sole carbon, nitrogen and energy source to build ammonia, carbon dioxide and acetic acid. Unlike most other Clostridia it is a specialist and not able to grow on sugars or different other substrates than purines.
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.
