Biological nitrogen fixation (BNF) refers to the process by which the nitrogen that is present abundantly in the atmosphere as non-reactive molecular dinitrogen (N 2 ) is converted into reactive forms that become available to plants and thereby to all life forms. The key process of BNF is ...

The biological nitrogen fixation, carried out by prokaryotes, leads to the reduction of molecular nitrogen to ammonia, subsequently assimilated in amino acids, and provides Earth's ecosystems with about 200 million tons N per year. This article describes the overall reaction of nitrogen fixation and...
Biological nitrogen fixation (BNF), a key reaction of the nitrogen cycle, is catalyzed by the enzyme nitrogenase. The best studied isoform of this metalloenzyme requires molybdenum (Mo) at its active center to reduce atmospheric dinitrogen (N2) into bioavailable ammonium. The Mo-dependent nitrogenas...

Some bacteria have the remarkable capacity to fix atmospheric nitrogen to ammonia under ambient conditions, a reaction only mimicked on an industrial scale by a chemical process that requires high temperatures, elevated pressure and special catalysts. The ability of microorganisms to use nitrogen gas ...
