Query: NC_009484:661089 Acidiphilium cryptum JF-5 chromosome, complete genome
Lineage: Acidiphilium cryptum; Acidiphilium; Acetobacteraceae; Rhodospirillales; Proteobacteria; Bacteria
General Information: Acidiphilium cryptum strain JF-5 was isolated under iron-reducing conditions from coal mine lake sediment and is able to grow by coupling the reduction of iron to the oxidation of glucose. Iron-reducing acidophile. Acidiphilium cryptum was first isolated from a supposedly pure culture of Thiobacillus ferrooxidans. This organism, a heterotrophic acidophile, has been isolated from acid mine drainage, hydrothermal vent water, and other acidic mineral environments.
Subject: NC_007964:3036771 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.
