Azotobacter chroococcum, coloured scanning electron micrograph (SEM). The genus Azotobacter is comprised of bacteria that require the presence of oxygen to grow and reproduce, and which are inhabitants of the soil. A noteworthy feature of Azotobacter is the ability of the bacteria to fix"" atmospheric nitrogen, by the conversion of this elemental form to ammonia. Research on Azotobacter chroococcum in crop production has manifested its significance in plant nutrition and its contribution to soil fertility. The possibility of using Azotobacter chroococcum in research experiments as microbial inoculant through production of growth substances and their effects on the plant has markedly enhanced crop production in agriculture.
