Rubrivivax benzoatilyticus JA2 produces indoles with simultaneous utilization of L-tryptophan. Fifteen chromatographically distinct indole derivatives were detected from the L-tryptophan-supplemented cultures of R. benzoatilyticus JA2. Nine of these were identified as, indole 3-acetamide, Methoxyindole-3-aldehyde, indole 3-aldehyde, methoxyindole-3-acetic acid, indole 3-acetic acid, indole-3-carboxylic acid, indole-3-acetonitrile, indole, and trisindoline. Tryptophan stable isotope feeding confirmed the indoles produced are from the supplemented L-tryptophan. Indole 3-acetic acid is one of the major products of L-tryptophan catabolism by R. benzoatilyticus JA2 and its production was influenced by growth conditions. Identification of indole 3-acetamide and tryptophan monooxygenase activity suggests indole 3-acetamide routed IAA biosynthesis in R. benzoatilyticus JA2. The study also indicated the possible multiple pathways of IAA biosynthesis in R. benzoatilyticus JA2.
