ABSTRACT:
Deoxynarasin antibiotic complex, comprising 20-deoxynarasin and 20-deoxy-epi-17-narasin, is produced by submerged aerobic fermentation of Streptomyces aureofaciens NRRL 11181. 20-Deoxynarasin and 20-deoxy-epi-17-narasin are separated and isolated by chromatography. The deoxynarasin complex, 20-deoxynarasin and 20-deoxy-epi-17-narasin are antibacterial and anticoccidial agents and also increase feed-utilization efficiency in ruminants.
