Beschreibung
Zusammenfassung:	A process for producing Rifamycin B substantially free from analogues sub-products and with high productivity. According to this process a mutant of the microorganism of the species Streptomyces Albovinaceus is cultivated in an aqueous nutrient medium of controlled initial pH containing assimilable sources of carbon, nitrogen and inorganic salts, in submerged aerobic conditions: Rifamycin B is produced which is then recovered by conventional methods.
