BIOSYNTHESIS OF INDOLE-3-ACETIC ACID BY <i>AZOSPIRILLUM </i>DEPENDING ON THE CULTIVATION CONDITIONS
This work is devoted to the study of the influence of various environmental factors (temperature, pH, tryptophan concentration) on the biosynthesis of indole-3-acetic acid (IAA) by Azospirillum strains isolated from the soil of the Perm region. The strains Azospirillum sp. (2) showed better IAA production at pH 7 and temperature 30°C (67,5 mcg /ml). The optimal tryptophan concentration is 500 mcg/ml.
