Abstract: In the present study a total of 16 different rhizospheric soil samples were collected from rhizospheric area of plants. Further the isolates were identify on the basis of cultural and biochemical characteristics. Enzyme profile of all the isolates were studied starch and urea hydrolysis as well as oxidase, cellulase and catalase were found to be positive. The study on effect of environmental parameter were studied and it was observed that the Azotobacter grows best 8.0 and 9.0 pH and it requires the temperature of 28°C and 2% salinity tolerant ability was observed. Azotobacter sp. also shows hydrogen cyanide (HCN) and ammonia production ability. N2 fixing capacity was studied by Kjeldahl Method. Highest N2 fixing ability was shown by AZ5 isolated is 0.0068 mg/ml.
Keywords: Azotobacter, Rhizosphere, N2 Fixation, Enzyme Profile, Envoirnmental Factor, Hydrogen cyanide and Ammonia.
