  skos:definition "[Henderson's] the process whereby atmospheric elemental nitrogen (dinitro­gen, N2) is reduced to ammonia (NH3), and which is carried out in the living world only by some free-living bacteria and cyanobacteria and by a few groups of bac­teria in symbiotic association with plants (the Rhizobium–legume association and the actinomycete–non-legume associations). The reaction is catalysed by the enzyme nitrogenase. Biological nitrogen fixation is the chief process by which atmospheric nitrogen enters the biosphere and becomes available as a nutrient to other organisms, although industrial nitrogen fixation is now of considerable significance. A smaller amount of atmospheric nitrogen is also fixed by conversion into nitrogen oxides by the action of lightning. see also nitrogen cycle."@en ;
