We have investigated the production of indigo‐related pigments from indoles by Nocardia globerula IFO 13510. Three pigments (indigo, a structural isomer of indigo and an unidentified pigment), coproduced in liquid cultures, were isolated by thin‐layer and high‐pressure liquid chromatography. The production of the pigments was dependent on medium composition and on the indole concentration in the cultures. In addition, the production of NN′‐dimethylindigo from 1‐methylindole was observed in liquid cultures.
