NITROBACTER VULGARIS

Class: Alpha Proteobacteria
Genus: Nitrobacter
Species: Nitrobacter vulgaris
Description: Nitrobacter vulgaris,G+C content of DNA ranged between 58.9 and 59.9 mol %. The isolates originated from divers environments. The cells were 0.5−0.8×1.2−2.0 μm in size and motile by one polar to subpolar flagellum. Cell-division normally occurred by budding. Polar caps of intracytoplasmic membranes as well as carboxysomes were present. The cells tended to excrete extracellular polymers forming aggregates or biofilms. Heterotrophic growth was slower than mixotrophic but often faster than litoautotrophic growth. In the presence of nitrite and organic substances the organisms often showed diphasic growth. First nitrite and then the organic material was oxidized. In the absence of oxygen growth was possible by dissimilatory nitrate reduction. Nitrite, nitric and nitrous oxide as well as ammonia were formed.Nitrobacter vulgaris is a rod-shaped, Gram-negative, and a chemoautotrophic bacterium. It plays an important role in the nitrogen cycle by oxidizing nitrite into nitrate in soil. It cannot tolerate highly alkaline conditions.
