Nitrifying bacteria are chemolithotrophic organisms that include species of genera such as Nitrosomonas, Nitrosococcus, Nitrobacter, Nitrospina, Nitrospira and Nitrococcus. These bacteria get their energy from the oxidation of inorganic nitrogen compounds. [1] . Types include ammonia-oxidizing bacteria ( AOB) and nitrite-oxidizing bacteria ( NOB ).
Bacteria (/ b æ k ˈ t ɪər i ə / ⓘ; sg.: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats.

Is Nitrobacter a Gram-negative bacteria?
Nitrobacter is a genus comprising rod-shaped, gram-negative, and chemoautotrophic bacteria. [1] . 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.

Nitrifikáló baktérium. Olyan kemoszintetizáló baktériumok, amelyek képesek maguknak nitrifikációval energiát nyerni. Ide tartoznak az ammónia-oxidáló, valamint a nitrit-oxidáló baktériumok. Ehhez a képességükhöz komplex, különleges előforduló membrán- és enzimrendszerrel rendelkeznek. Nagy szerepet játszanak a ...
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 (NH 4 +) conditions. NO 2 - + 1/2O 2 -> NO 3 - Genomics. Nitrobacter Genome Projects (from Genomes OnLine Database)

Sep 4, 2023 · MicrobeWiki is a free wiki resource on microbes and microbiology, authored by students at many colleges and universities. Curated pages such as those linked to the Taxonomy Index are reviewed and updated by microbiologists at Kenyon College. Student pages authored independently, or for coursework, are not monitored further.
Publish with us. Policies and ethics. The biological oxidations of ammonia to nitrite and nitrite to nitrate, collectively referred to as nitrification, are carried out in nature by two physiological groups of Gram-negative, chemolithotrophic bacteria. The organisms in both groups fix carbon dioxide via...
