RESUMO

Thirteen red strains of Actinomadura (Nocardia) pelletieri and three of A. madurae were shown to produce prodigiosin-like pigments. Both of the two major pigments which were observed on thin-layer chromatograms had RF values significantly greater than prodigiosin. The main pigment from A. madurae 953 was shown by mass and nuclear magnetic resonance spectroscopies to be nonylprodigiosin. The major pigment from A. pellitieri had a C11H22 side chain in a ring form, but it was distinctly different from metacycloprodigiosin. “Prodiginine” was proposed as a name for the invariant aromatic portion of the prodigiosin structure.
