The Nitrobacteraceae are a family of gram-negative, aerobic bacteria. They include plant-associated bacteria such as Bradyrhizobium, a genus of rhizobia associated with some legumes. It also contains animal-associated bacteria such as Afipia felis, formerly thought to cause cat-scratch disease. Others are free-living, such as Rhodopseudomonas, a purple bacterium found in marine water and soils. The strain Rhodopseudomonas palustris DX-1 can generate an electric current with no hydrogen production, a trait being explored in the development of the microbial fuel cell.[2] The genus Afipia has also been found in the atmosphere, where it uses methylsulfonylmethane as a carbon source.[3]

The bacteria of this family derive their energy from oxidizing ammonia to nitrite, or by oxidizing nitrite to nitrate. They are commonly found in freshwater and soil.

Phylogeny

[edit | edit source]

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN).[1] The phylogeny is based on whole-genome analysis.[4]
