Nitrobacter winogradskyi Nb-255

Nitrobacter winogradskyi Nb-255 is a Gram-negative, facultatively anaerobic bacterium characterized by its bacilli shape and mobility, facilitated by the presence of flagella. This organism thrives in terrestrial habitats and is classified as a lithotroph, deriving its energy from inorganic compounds. It exhibits mesophilic temperature preferences, indicating an optimal growth range typical of moderate temperatures. N. winogradskyi Nb-255 is a free-living bacterium with a single replicon and possesses two membranes, a feature common among Gram-negative bacteria. Importantly, it does not exhibit pathogenicity, making it a non-harmful member of its ecosystem. The accession number for this strain is NC_007406.1, which serves as a reference for genomic studies and further research. From an ecological perspective, the free-living nature of Nitrobacter winogradskyi Nb-255 positions it as a critical player in nitrogen cycling within terrestrial environments. By oxidizing nitrite to nitrate, it contributes to soil fertility and nutrient availability for plants, thus playing a significant role in maintaining the health of terrestrial ecosystems. This bacterium exemplifies the importance of lithotrophic microorganisms in sustaining nutrient cycles and supporting biodiversity in various habitats.
