FIELD: biotechnology.
SUBSTANCE: strain of the Streptomyces virginiae microorganism - producer of the virginiamycine antibiotic, deposited in VKM under registration number VKM Ac-2738D and method for virginiamycine antibiotic production. The method for virginiamycine antibiotic production provides cultivation of Streptomyces virginiae VKM Ac-2738D microorganism strain, antibiotic sorption from the culture fluid during biosynthesis to DIAION™ HP20 or DIAION™ HP21 polymeric resins followed by resin separation by filtering and antibiotic elution by acetone, methylene chloride or alcohols and eluate concentration in a vacuum to obtain dry matter.
EFFECT: simplification of isolation and purification of the antibiotic obtained.
