Genera[2]

The Bradyrhizobiaceae are a family of bacteria, with ten genera. 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.[3] The genus Afipia has also been found in the atmosphere, where it uses methylsulfonylmethane as a carbon source.[4]

Based on the taxonomical classification of the SSU rRNA gene sequences recovered, Afipia sp. (Alphaproteobacteria) comprised over 50% of the total communities sampled off the California coast and during the transit flights. (…) This group [Afipia] is commonly found in aquatic environments and is known to use dimethyl sulfone (DMSO2) as a sole carbon source. DMSO2 represents an intermediate of the oxidation of dimethyl sulfide (DMS), which is commonly found in the marine atmosphere (page 3 and 5 of 6, quotes slightly edited).
