The metabolism of tryptophan by Taphrina deformans has been studied to confirm the reported ability of this organism to produce tryptamine. Such amine production was not observed, despite use of amine oxidase inhibitors at levels which should have resulted in the accumulation of tryptamine in the medium. It has been shown that the metabolites of tryptophan include indolepyruvic acid, indolelactic acid, tryptophol, and indoleacetic acid, and that the original report of tryptamine production must be reevaluated in light of the extraction procedures employed.
