THE METHOD OF BIOTECHNOLOGICAL PREPARATION OF LINCOMYCIN DERIVATIVES AND ITS USING

摘要

Lincomycin derivatives are produced by biotechnological cultivation of Streptomyces lincolnensis ATCC 25466 with at least one gene of the 4-L-propylproline biosynthesis coding cluster inactivated. A substitute of the component whose synthesis is blocked by inactivation is added to the medium. In this way new, biologically active lincomycin derivatives are produced biosynthetically.
