Acinetobacter haemolyticus, A19 produced IAA in presence of different wheat root exudates and also in absence of standard precursor 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 structural analog of IAA was used as a precursor. HPLC analysis showed that using tryptophan and indole as precursors, IAA was synthesized by A19 by two possible routes via tryptamine and indole-3 acetonitrile as intermediates.
