Indole acetic acid (IAA) production by different bacterial sample isolated from soil of different districts of Uttar Pradesh

Abstract

Indole acetic acid (IAA) production is a major property of soil bacteria namely Pseudomonas and Bacillus. The present work deals with indole acetic acid producing bacteria from the soil of different district of Uttar Pradesh. Optimization of indole acetic acid production was carried out at different cultural conditions of pH and temperature with varying media components such as carbon and nitrogen source, tryptophan concentration. In conclusion the study suggests the IAA producing bacteria as efficient biofertilizer inoculants to promote plant growth.
