  2. Nitrifying bacteria - Wikipedia

    en.wikipedia.org/wiki/Nitrifying_bacteria

    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).

  3. Nitrification - Wikipedia

    en.wikipedia.org/wiki/Nitrification

    Nitrogen cycle. Nitrification is the biological oxidation of ammonia to nitrate via the intermediary nitrite.Nitrification is an important step in the nitrogen cycle in soil.The process of complete nitrification may occur through separate organisms [1] or entirely within one organism, as in comammox bacteria.

  4. Nitration - Wikipedia

    en.wikipedia.org/wiki/Nitration

    Nitration reactions are notably used for the production of explosives, for example the conversion of guanidine to nitroguanidine and the conversion of toluene to trinitrotoluene (TNT). Nitrations are, however, of wide importance virtually all aromatic amines are produced from nitro precursors. Millions of tons of nitroaromatics are produced ...

  5. Nitrogen cycle - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_cycle

    The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmospheric, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation ...

  6. Nitrogen fixation - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_fixation

    Nitrogen fixation. Nitrogen fixation is a chemical process by which molecular dinitrogen (N2) is converted into ammonia (NH3). [ 1 ] It occurs both biologically and abiologically in chemical industries. Biological nitrogen fixation or diazotrophy is catalyzed by enzymes called nitrogenases. [ 2 ]

  7. Denitrification - Wikipedia

    en.wikipedia.org/wiki/Denitrification

    Denitrification is a microbially facilitated process where nitrate (NO 3−) is reduced and ultimately produces molecular nitrogen (N 2) through a series of intermediate gaseous nitrogen oxide products. Facultative anaerobic bacteria perform denitrification as a type of respiration that reduces oxidized forms of nitrogen in response to the ...

  8. Reactive nitrogen species - Wikipedia

    en.wikipedia.org/wiki/Reactive_Nitrogen_Species

    From Novo and Parola, 2008. [1] Reactive nitrogen species (RNS) are a family of antimicrobial molecules derived from nitric oxide (•NO) and superoxide (O 2•−) produced via the enzymatic activity of inducible nitric oxide synthase 2 (NOS2) and NADPH oxidase respectively. NOS2 is expressed primarily in macrophages after induction by ...
