  • Process for preparing lincomycin
    Patent number: 4271266
    Abstract: Microbiological process for preparing the antibiotic lincomycin at temperatures ranging from 18.degree. C. to 45.degree. C. using the newly discovered microorganism Streptomyces vellosus. The subject process advantageously results in the preparation of lincomycin without the concomitant production of lincomycin B (4'-depropyl-4'-ethyllincomycin). The absence of lincomycin B production results in increased lincomycin recovery efficiency.
