Dehalobacter is a genus in the phylum Bacillota (Bacteria).[1]

Etymology

edit

The generic name Dehalobacter derives from Latin de, from; halogenum from Swedish, coined by Swedish chemist Baron Jöns Jakob Berzelius (1779–1848) from Greek hals, halos "salt" + gen "to produce", so called because a salt is formed in reactions involving these elements; a rod bacter, nominally meaning "a rod", but in effect meaning a bacterium, a rod; giving Dehalobacter, a halogen-removing, rod-shaped bacterium.[1][2]

Species

edit

The genus contains a two species,[2] namely D. restrictus (Holliger et al. 1998), type species of the genus. The specific name is from Latin restrictus, limited, restricted, confined, referring to the limited substrate range used.[3] Recently, Dehalobacter sp. UNSWDHB, which dechlorinate chloroform to dichloromethane, and its reductive dehalogenase were identified.[4][5]
