✦ Synopsis

The effect of potential precursors of Indole-3-acetic acid (IAA) on the growth (increase in dry weight) of Anacystis nidulans, Chlorogloea ]ritschii, Phormidium /oveolarum, Nostoc muscorum and ToIypothrix tenuis have been investigated under as sterile conditions as possible.

Tryptamine showed a marked stimulation of growth indicating its possible conversion to IAA. Tryptophan at a hormonal concentration promoted growth in only 1 species, Chlorogloea /ritschii. Indole stimulated the growth of Chlorogloea /ritschii, Nostoc muscorum and Tolypothrix tenuis. Anthranilic acid promoted the growth of Nostoc muscorum, it failed to stimulate the growth of Chlorogloea/ritschii. Anthranilonitrile promoted the growth of Nostoc muscorum and Chlorogloea/ritschii. fl-Alanine promoted the growth of Nostoc muscorum, Tolypothrix tenuis and Chlorogloea/ritschii at hormonal concentrations.

The metabolism of L-tryptophan (mcthylene-C 14) by Chlorogloea /ritschii has been studied in sterile conditions. This organisIa can produce Indole-3- Acetic acid (IAA) from tryptophan. Tryptamine has been shown to be one of the intermediate compound in the conversion of tryptophan to IAA. The format
