Antibiotic A-51568 is produced by submerged, aerobic fermentation of new Nocardia orientalis NRRL 15232. The antibiotic is effective against gram-positive organisms.
摘要:
Antibiotic A-32390 complex, comprising factor A and other structurally related factors, is produced by cultivation of Pyrenochaeta sp. NRRL 5786 under submerged aerobic conditions, and isolated by extraction of the broth. Individual A-32390 factor A is separated by chromatography. The A-32390 complex, individual factor A and acyl ester derivatives of factor A inhibit dopamine-.beta.-hydroxylase and have antifungal, antibacterial, and hypotensive activity.

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.
