Nitrogenase, the enzyme responsible for biological nitrogen fixation (BNF), has a wide taxonomic distribution in the bacteria and archaea, but is confined to a limited number of species. Among these, soil bacteria called rhizobia, which form symbiotic nodules on the roots of legumes (Fabaceae), ...
LinxiWang,JiaguoYu, inInterface Science and Technology, 2023 1.5.5Photocatalytic N2fixation Nitrogen fixationis an important process in the nitrogen cycle. In this process, the N2from air is reduced to NH3(or NH4+), which can be further converted to nitrogen-containing organic compounds, such as...
ammonia from atmospheric nitrogen. This process is carried out by specific bacteria that are found near legumes like soybeans and garden peas. The relationship between the bacteria and the legumes is mutualistic, meaning that both organisms benefit.Read Nitrogen Fixation Definition, Cycle & Importance...
Nitrogen fixation, any natural or industrial process that causes free nitrogen, which is a relatively inert gas plentiful in air, to combine chemically with other elements to form more-reactive nitrogen compounds such as ammonia, nitrates, or nitrites. L

Definition The term Nitrogen Fixation involves the combination under natural conditions of molecular nitrogen with oxygen or hydrogen to give oxides or ammonia which can then be incorporated into the biosphere. Molecular nitrogen or dinitrogen (N 2 ) is the main component of the atmosphere but it ...
