Production of indole acetic acid: The characterized bacterium was grown at 30 °C for 24 h in TSB. The culture was centrifuged and the supernatant was extracted with equal volume of ethyl acetate and evaporated under vacuum at 40 °C . The residue was detected by paper chromatography using ethyl acetate in chloroform (3:2) as eluent and FeCl3 (0.05% in sulphuric acid) as a color reagent
