Query: NC_014313:165490 Hyphomicrobium denitrificans ATCC 51888 chromosome, complete
Lineage: Hyphomicrobium denitrificans; Hyphomicrobium; Hyphomicrobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Environment: Fresh water; Temp: Mesophile. An aerobic, motile Gram-negative bacterium. Hyphomicrobium denitrificans has a biphasic life style, which consists of a motile phase of flagellated swarmer cells, and a cessile phase in which a long prosthecate is produced at one end of the bacteria through which budding cells emerge. Newly budded cells in turn produce flagella and go through a motile phase and the cycle continues. These organisms can colonize the surfaces of marine environments which enables additional species to colonize at later stages. This organism is also able to utilize methanol as a sole source of energy.
Subject: NC_009138:1138917 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.
