Abstract
The invention provides a method for preparing streptogramins using genetically-modified microorganisms to influence the biosynthesis of at least one of the precursors of the group B streptogramins. Cultures of the genetically-modified microorganisms are supplemented with a least one precursor that is different from the streptogramin precursor whose biosynthesis is altered and the streptogramins produced are recovered.
