Abstract

B. licheniformis MML2501 which was isolated from groundnut rhizosphere soil showed increased populations on spermozphere colonisation and significantly increased the seed germination and other growth parameters in groundnut under in vitro conditions. B. licheniformis MML2501 did not solubilise phosphate but produced indole acetic acid (IAA), with a maximum of 23 μg/ml under optimised conditions such as pH 7.0, temperature 35°C, tryphtophan at a concentration of 16 mM and at 200 rpm shaken conditions. The production of IAA by B. licheniformis MML2501 was further confirmed by TLC and HPLC analyses, in which the Rf value and retention time of 0.66 and 4.1 min respectively, match with that of the authentic IAA. Seed treatment of B. licheniformis MML2501 in groundnut showed a significant increase in seed germination, other growth parameters and yield parameters under potted plant experiments.
