Abstract

The effects of incubation time, temperature, pH, and agitation on indole-3- acetic acid and gibberellic acid production in Aspergillus niger were studied. For indole-3-acetic acid production, 6 days of incubation at 25 degrees C and pH 6.0 was found to be optimum. Optimum conditions for gibberellic acid production were 12 days of incubation at 30 degrees C and pH 5.0. Agitation increased both indole-3-acetic acid and gibberellic acid production.
