The ability of Azotobacter chroococcum to fix nitrogen as influenced by aeration was studied under three different conditions namely, continously shaken, continuously stationary and partially shaken cultures. Continuously shaken cultures showed six fold increase in population over the partially shaken one and twice as much over the continuously stationery one. Nitrogen fixed per gram of sugar consumed was 58.4 mg with continuously stationary culture, 84.3 mg with partially shaken culture and 68.4 mg with continuously shaken culture. Highest per cell fixation of nitrogen was obtained with partially shaken culture followed by continuously stationary and continuously shaken cultures.
