Abstract
PURPOSE: To prepare rifamycin S which is a raw material of rifampicin anti-tuberculous agent, by the aerobical cultivation of bacteria belonging to Nocardia genus in a nutrient medium.
CONSTITUTION: Rifamycin-producing bacteria belonging to Nocardia genus, pref. Nocardia K-468 (FERM-P No.4391), are aerobically cultured at 20W40°C and pH5.0W9.0 for usually 2W10 days; and the objective rifamycin S is obtained by extracting the cultured bacterial cells and the filtrate, and purifying the extract.
