Acinetobacter haemolyticus, A19 produced IAA presence of different wheat root exudates and also in absence of standard precutsor tryptophan in production medium. IAA production was increased with concentration of L-tryptophan from 50–200μg/ml in growth medium. However similar results were not obtained when indole, a structutal analog of IAA was used as a preCUTSOr. HPLC analysis showed that using try ptophan and indole as precutsots, IAA was synthesized by A19 by two possible routes via tryptamine and indole-3 acetonitrile as intermediates.
