Fixation process

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 dinitrogen, a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms. Biological nitrogen fixation or diazotrophy is an important microbe-mediate… WebMechanism of biological nitrogen fixation: There are some basic requirements of nitrogen fixation; Presence of enzyme nitrogenase and hydrogenase A protective mechanism for the enzyme nitrogenase against O 2 A non-heme iron protein, Ferredoxin as an electron carrier Hydrogen containing system like pyruvate, hydrogen, sucrose, glucose etc. A constant …
