Azotobacter as isolated by a Dutch Scientist Beizerinchia in 1901. Azotobacter chroococcum is a bacterium discovered in 1901 by Martinus Beijerinck, noted for his discovery of an infectious agent smaller than a bacterium which is responsible for tobacco mosaic disease, as well as his role in founding the field of virology.It has the ability to fix atmospheric nitrogen, and was the first aerobic, free-living nitrogen fixer discovered. Hormone production IAA All Azotobacter isolates tested were able to produce the IAA with different concentration levels. shape bacteria, which can fix atmospheric nitrogen.

These strains were purified and characterized through microscopical and biochemical test for cell shape, pigmenta-tion, colony size, Gram reaction and catalase activity were identified as Azotobacter sp These strains showed wide variability to these characters. The present study is concerned with the optimization of growth conditions for Azotobacter species. The genus Azotobacter is distinguished from other genera in the family (Azomonas, Beijerinckia, andDerxia) by the ability ofits membersto form metabolically dormant cysts after exponential growth or upon induction of vegetativecells withspecificreagents (97).
