G.Kh.Kadirova, Z.S.Shakirov

At the concentration of NaCl at 200 mM, the nitrogen-fixing activity of N. calcicola insignificantly dropped against control and reached 88.2 nmol Ñ2Í4 flask/hour. After seven days of cultivation at the concentration of tryptophan; 3 and 5 mg/ml the synthesis of indole-3-acetic acid (IAA) in N. calcicola N 25 corresponded to the values 50,45; 97,5 and 210 mg/l.
