The process of nitrification
WebbDefinition of Nitrification Process. Nitrification is a two-step process mediated by specific groups of soil microorganisms. Nitritation: The... Nitrification is a process of nitrogen compound oxidation (effectively, loss of electrons from the nitrogen atom to the oxygen atoms), and is catalyzed step-wise by a series of enzymes. 2 NH 4 + + 3 O 2 2 NO 2 − + 4 H + + 2 H 2 O {\displaystyle {\ce {2NH4+ + 3O2 -> 2NO2- + 4H+ + 2H2O}}} ( Nitrosomonas , … Visa mer Nitrification is the biological oxidation of ammonia to nitrite followed by the oxidation of the nitrite to nitrate occurring through separate organisms or direct ammonia oxidation to nitrate in comammox bacteria. The transformation … Visa mer The idea that oxidation of ammonia to nitrate is in fact biological process was first given by Louis Pasteur in 1862. Later in 1875, Alexander Müller during quality assessment of water from wells in Berlin noted that ammonium was stable in sterilized solutions … Visa mer In the marine environment, nitrogen is often the limiting nutrient, so the nitrogen cycle in the ocean is of particular interest. The nitrification step … Visa mer Nitrification inhibitors are chemical compounds that slow the nitrification of ammonia, ammonium-containing, or urea-containing fertilizers, which are applied to soil as fertilizers. These inhibitors can help reduce losses of nitrogen in soil that would otherwise be … Visa mer Ammonia oxidation The oxidation of ammonia into nitrite (also known as nitritation) is performed by two groups of organisms, ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA ). AOB Visa mer Both steps are producing energy to be coupled to ATP synthesis. Nitrifying organisms are chemoautotrophs, and use carbon dioxide as their carbon source for growth. Some AOB … Visa mer • Substrate availability (presence of NH4 ) • Aeration (availability of O2) • Well-drained soils with 60% soil moisture Visa mer
