PROCESS FOR PRODUCING ANTIBIOTIC COMPLEX AAD 216 AND MAIN COMPONENTS THEREOF BY MEANS OF FERMENTATION WITH KIBDELOSPORANGIUM ARIDUM

摘要

A novel antibiotic complex of "Vancomycin-like" antibiotics, AAD 216 complex, is produced by the cultivation of a fermentation broth containing Kibdelosporangium aridum Shearer gen. nov., sp. nov. ATCC 39323 microorganisms in an aqueous nutrient medium under submerged aerobic conditions. The AAD 216 complex and its major bioactive components; AAD 216A, AAD 216B, and AAD 216C exhibit antibiotic activity and growth promotant activity.
