The biological route to fixing nitrogen is done by diazotrophs, nitrogen-fixing bacteria that contain an enzyme called nitrogenase. In contrast to the Haber-Bosch process, nitrogenase can be ...

Limnology and Oceanography, Vol. 54, No. 2 (Mar., 2009), pp. 537-547 (11 pages) Latitudinal distribution of diazotrophs and their nitrogen (N₂) fixation activity were investigated in the western North ...

Diazotrophs are a specific group of bacteria and Archaea which express the nitrogenase enzyme. We are interested in understanding temporal and spatial variations in the diazotrophic community in the ...
