    Area of Science:

    • Microbiology
    • Organic Chemistry
    • Pharmacology

    Background:

    • Streptomyces mutabilis produces novel secondary metabolites.
    • Polyether antibiotics are a significant class of antimicrobial agents.

    Purpose of the Study:

    • To isolate and characterize a new antibiotic from Streptomyces mutabilis NRRL 8088.
    • To determine the structure and biological activity of the novel metabolite.

    Main Methods:

    • Isolation of the metabolite as its sodium salt (C41H69NaO12).
    • Structure elucidation using X-ray crystallography of the potassium salt (C41H69KO12).

    Main Results:

    • Mutalomycin, a monocarboxylic acid with six heterocyclic rings, was identified.
