Webb11 apr. 2024 · Lee PKH, He J, Zinder SH, Alvarez-Cohen L. Evidence for nitrogen fixation by “Dehalococcoides ethenogenes” strain 195. Appl Environ Microbiol. 2009;75:7551–5. Nitrogen fixation or biological nitrogen fixation (BNF) is a chemical process by which molecular nitrogen (N 2), which has a strong triple covalent bond, is converted into ammonia (NH 3) or related nitrogenous compounds, typically in soil or aquatic systems but also in industry. The nitrogen in air is molecular … Visa mer Biological nitrogen fixation was discovered by Jean-Baptiste Boussingault in 1838. Later, in 1880, the process by which it happens was discovered by German agronomist Hermann Hellriegel and Hermann Wilfarth [ Visa mer Biological nitrogen fixation (BNF) occurs when atmospheric nitrogen is converted to ammonia by a nitrogenase enzyme. The overall reaction for BNF is: $${\displaystyle {\text{P}}_{i}}$$ The process is coupled to the hydrolysis of 16 equivalents of Visa mer Nitrogen can be fixed by lightning converting nitrogen gas (N 2) and oxygen gas (O 2) in the atmosphere into NOx (nitrogen oxides).
