[Transformation of L-tryptophan by Rhizobium phaseoli]

Transformation of L-tryptophan was studied in Rhizobium phaseoli 680. The culture was capable of oxidation decarboxylation, transamination and degradation of L-tryptophan. Four metabolites were identified: tryptamine, indolyl-3-pyruvic, indolyl-3-acetic and anthranilic acids. The fifth metabolite has not been yet identified.
