Although oxygen once promoted nitrogen fixation by making molybdenum available in water, it also directly poisons nitrogenase enzymes.
Although it is unlikely that biomimetic methods that are competitive with the Haber process will be developed, intense effort has been directed toward understanding the mechanism of biological nitrogen fixation.
At least 50 molybdenum enzymes are now known in bacteria and animals, although only bacterial and cyanobacterial enzymes are involved in nitrogen fixation.
Biological nitrogen fixation in free-living cyanobacteria and in the root nodules of plants also produces ammonia from molecular nitrogen.
Catalysts for nitrogen fixation : nitrogenases, relevant chemical models and commercial processes.
Its roots also encourage nitrogen fixation, which produces higher crop yields.
