Nitrobacteraceae

	Nitrobacteraceae 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. The genus ''Afipia'' has also been found in the atmosphere, where it uses methylsulfonylmethane as a carbon source.(page 3 and 5 of 6, quotes slightly edited). 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.

	Afipia Felis ''Afipia felis'' is the type species of the ''Afipia'' bacterial genus. It was formerly thought to cause cat-scratch disease. It is a Gram-negative, oxidase-positive, nonfermentative rod in the alpha-2 subgroup of the class Proteobacteria. It is motile by means of a single flagellum A flagellum (; ) is a hairlike appendage that protrudes from certain plant and animal sperm cells, and from a wide range of microorganisms to provide motility.

picture info	Nitrobacter ''Nitrobacter'' is a genus comprising rod-shaped, gram-negative, and chemoautotrophic bacteria. The name ''Nitrobacter'' derives from the Latin neuter gender noun ''nitrum, nitri'', alkalis; the Ancient Greek noun βακτηρία'','' βακτηρίᾱς'','' rod. They are non-motile and reproduce via budding or binary fission. ''Nitrobacter'' cells are obligate aerobes and have a doubling time of about 13 hours. ''Nitrobacter'' play an important role in the nitrogen cycle by oxidizing nitrite into nitrate in soil and marine systems. Unlike plants, where electron transfer in photosynthesis provides the energy for carbon fixation, ''Nitrobacter'' uses energy from the oxidation of nitrite ions, NO2−, into nitrate ions, NO3−, to fulfill their energy needs. ''Nitrobacter'' fix carbon dioxide via the Calvin cycle for their carbon requirements. ''Nitrobacter'' belongs to the Alphaproteobacteria class of the Pseudomonadota.

	Bradyrhizobium ''Bradyrhizobium'' is a genus of Gram-negative soil bacteria, many of which fix nitrogen. Nitrogen fixation is an important part of the nitrogen cycle. Plants cannot use atmospheric nitrogen (N2); they must use nitrogen compounds such as nitrates. Characteristics ''Bradyrhizobium'' species are Gram-negative bacilli (rod-shaped) with a single subpolar or polar flagellum. They are common soil-dwelling micro-organisms that can form symbiotic relationships with leguminous plant species where they fix nitrogen in exchange for carbohydrates from the plant. Like other rhizobia, many members of this genus have the ability to fix atmospheric nitrogen into forms readily available for other organisms to use. Bradyrhizobia are also major components of forest soil microbial communities, where strains isolated from these soils are not typically capable of nitrogen fixation or nodulation. They are slow-growing in contrast to ''Rhizobium'' species, which are considered fast-growing rhizobia. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Purple Bacteria Purple bacteria or purple photosynthetic bacteria are Gram-negative proteobacteria that are phototrophic, capable of producing their own food via photosynthesis. They are pigmented with bacteriochlorophyll ''a'' or ''b'', together with various carotenoids, which give them colours ranging between purple, red, brown, and orange. They may be divided into two groups – purple sulfur bacteria ( Chromatiales, in part) and purple non-sulfur bacteria ( Rhodospirillaceae). Purple bacteria are anoxygenic phototrophs widely spread in nature, but especially in aquatic environments, where there are anoxic conditions that favor the synthesis of their pigments. Taxonomy Purple bacteria belong to phylum of ''Pseudomonadota''. This phylum was established by Carl Woese in 1987 calling it "purple bacteria and their relatives" even if this is not appropriate because most of them are not purple or photosynthetic. Purple bacteria are distributed between 3 classes:''Alphaproteobacteria'', ''Betap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
