    A new crystalline antibiotic, viridenomycin, was discovered from Streptomyces viridochromogenes. This lipophilic antibiotic shows potent activity against Trichomonas vaginalis and gram-positive bacteria.

    Area of Science:

    • Microbiology
    • Pharmacology
    • Natural Products Chemistry

    Background:

    • The emergence of drug-resistant pathogens necessitates the discovery of novel antimicrobial agents.
    • Streptomyces species are a rich source of diverse bioactive compounds with therapeutic potential.

    Purpose of the Study:

    • To isolate and characterize a new antibiotic from Streptomyces viridochromogenes.
    • To evaluate the antimicrobial activity of the novel compound.

    Main Methods:

    • Isolation of the antibiotic from the culture broth of Streptomyces viridochromogenes strain No. T-24146.
    • Physicochemical characterization including spectral analysis (absorption maximum at 310 nm).
    • Antimicrobial susceptibility testing against Trichomonas vaginalis and gram-positive bacteria.
