Studies on the hormonal relationships of algae in pure culture

Abstract
The metabolism of L-tryptophan (methylene-C14) by Chlorogloea fritschii has been studied in sterile conditions. This organism 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 formation of Indole-3-pyruvic acid could not be demonstrated.
