Query: NC_008344:49039 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_009138:1974935 Herminiimonas arsenicoxydans, complete genome
Lineage: Herminiimonas arsenicoxydans; Herminiimonas; Oxalobacteraceae; Burkholderiales; Proteobacteria; Bacteria
General Information: Herminiimonas arsenicoxydans was isolated from heavy metal contaminated sludge from an industrial water treatment plant. This organism has a number of mechanisms for metabolizing arsenic allowing it to effectively colonize arsenic-contaminated environments. A bacterium capable of oxidizing and reducing arsenic. This heterotrophic bacterium is capable of reducing and oxidizing arsenic with the objective of detoxification. Arsenic is both a product from natural sources and of human activities, and is widely distributed in the environment, essentially in 3 different oxidation states: As (-III) (arsine), As (+III) (arsenite) and As (+V) (arseniate). The ecology of this metalloid is strongly dependent on microbial transformations which affect the mobility and bioavailability as well as the toxicity of arsenic in the environment.
