Abstract
Indole acetic acid (IAA) production is a major property of rhizosphere bacteria that stimulates and facilitates plant growth. The present work deals with the isolation, characterization, and identification of indole acetic acid-producing bacteria from the rhizospheric soil. Out of four organisms isolated from serial dilution, Sample-2 confirmed thick bands of IAA production by TLC analysis. 16s rRNA analysis showed the isolated organism was found to be Pseudomonas fluorescence with a similarity of 88%. The isolated organism treat plants showed increased shoot and root length in plant growth analysis. In conclusion, the isolated IAA-producing bacteria can be used as efficient biofertilizer inoculants to promote plant growth.
