Query: NC_009138:1518315 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.

General Information: This strain was isolated from a polluted creek in Urbana, Illinois, USA by enrichment culture with ethylbenzyne as a sole source of carbon and energy. Its ability to degrade several different compounds including benzene, toluene, and ethylbenzene makes this species useful in the bioremediation of sites contaminated with multiple aromatic hydrocarbons. Underground gasoline tanks which have developed leaks can contaminate soil and water with a variety of these compounds. Bacteria belonging to the Pseudomonas group are common inhabitants of soil and water and can also be found on the surfaces of plants and animals. Pseudomonas bacteria are found in nature in a biofilm or in planktonic form. Pseudomonas bacteria are renowned for their metabolic versatility as they can grow under a variety of growth conditions and do not need any organic growth factors. As they are metabolically versatile, and well characterized, it makes them great candidates for biocatalysis, bioremediation and other agricultural applications. Certain strains have been used in the production of bioplastics.
