Research on Rhizobacteria Production of Indole Acetic Acid (IAA) and Its Potential to Promote Growth

Abstract

This study focused into how soil bacteria produce indole acetic acid. Using accepted techniques, the soil rhizospheric bacteria were isolated and characterised. Two bacterial species with varying potentials were found when rhizosphere bacteria were screened for the ability to produce IAA. The microorganisms are identified as Bacillus sp I (RSS2), Micrococcus sp I (RSS2). The benefits of inoculating maize seeds with different bacterial isolates to promote germination and growth were investigated through hydroponic research. In addition to improving germination, materialization of maize seeds encouraged the elongation of roots and shoots. The findings demonstrated that a high IAA-producing bacterial inoculation increased the number of lateral roots.
