  • Four free-living nitrogen fixing bacteria, namely NC 2, NC 4, NC 10 and NC 11 were tested for nitrogenase activity. NC 10 performed the highest nitrogenase activity (3.01 x 10–3 mol/h/ml), followed by NC 4 (6.84 x 10–4 mol/h/ml), NC 2 (2.36 x 10–5 mol/h/ml) and NC 11 (7.48 x 10–5 mol/h/ml). The nitrogenase activity of mix culture was recorded as 7.48 x 10–5 mol/h/ml. Beijerinckia medium was the most suitable growth medium for all four organisms, followed by Derxia medium and Ashby’s medium. In… CONTINUE READING
