WebAzotobacter is a renowned nonsymbiotic nitrogen fixer. Since the discovery of Azotobacter in 1901, it has magnetized microbiologists’ attention for its interesting potential in agriculture for nitrogen fixation as well as synthesis of biologically active substances. Azotobacter is a genus of usually motile, oval or spherical bacteria that form thick-walled cysts (and also has hard crust) and may produce large quantities of capsular slime. They are aerobic, free-living soil microbes that play an important role in the nitrogen cycle in nature, binding atmospheric nitrogen, … Meer weergeven Morphology Cells of the genus Azotobacter are relatively large for bacteria (2–4 μm in diameter). They are usually oval, but may take various forms from rods to spheres. In microscopic … Meer weergeven Azotobacter species are free-living, nitrogen-fixing bacteria; in contrast to Rhizobium species, they normally fix molecular nitrogen from the atmosphere without symbiotic relations with plants, although some Azotobacter species are associated … Meer weergeven Owing to their ability to fix molecular nitrogen and therefore increase the soil fertility and stimulate plant growth, Azotobacter … Meer weergeven • "Azotobacter". • Euzéby, J.
