    Nitrobacter - Wikipedia

    • 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 o… 展开

    Morphology and characteristics

    Nitrobacter are gram-negative bacteria and are either rod-shaped, pear-shaped or pleomorphic. They are typically 0.5–0.9 μm in width and 1.0–2.0 μm in length and have an intra-cytomembrane polar cap. Due to the presence of … 展开

    Phylogeny

    16s rRNA sequence analysis phylogenetically places Nitrobacter within the class of Alphaproteobacteria. Pairwise evolutionary distance measurements within the genus are low compared to those found in other genera, … 展开

    Nitrification

    Nitrification is a crucial component of the nitrogen cycle, especially in the oceans. The production of nitrate (NO3 ) by oxidation of nitrite (NO2 ) is accomplished by nitrification - the process that produces the inorganic nitr… 展开

    Metabolism and growth

    Members of the genus Nitrobacter use nitrite as a source of electrons (reductant), nitrite as a source of energy, and CO2 as a carbon source. Nitrite is not a particularly favourable substrate from which to gain energy. Thermo… 展开
