    Abstract:
    A taxonomic study of Streptomyces X-14077 (NRRL 8144), which produces a water-soluble purple-red pigment complex, revealed it to be a new species which has been named Streptomyces echinoruber sp. nov. The pigment complex was produced in deep culture fermentation and isolated by solvent extraction and concentration. The major pigment component, rubrolone, has low toxicity and may have potential as a food coloring agent. It appears to be devoid of antibiotic activity.
