WebWhat is the process that Azotobacter uses to produce ammonia in soil? Biological nitrogen fixation (BNF), discovered by Beijerinck in 1901 (Beijerinck 1901), is carried out by a specialized group of prokaryotes. These organisms utilize the enzyme nitrogenase to catalyze the conversion of atmospheric nitrogen (N 2) to ammonia (NH 3). WebWhich process hinders clarification of the deepest branchings in a phylogenetic ... What important criterion was used in the late 1960s to distinguish between the three ...
