Abstract:
Nutritional requirement of microorganism can depend mainly on the other nutrient components in defined media.Media enhance the growth and predominance of particular type of bacterium and not allow the other organisms.Influence of Dipotassium phosphate (K2HPO4) and Ferrous sulphate (FeSO4) on Azotobacter chroococcum were measured at various concentrations in Jensen’s medium. Dipotassium phosphate ranging from 0.2 gl-1 to 2.0 gl-1 and Ferrous Sulphate from 0.02gl-1 to 0.20 gl-1. The bacteria showed maximum growth were found at 0.6gl-1 K2HPO4and at 0.1 gl-1 FeSO4.
