Antibiotic u - 59 761, process for its production and isolation as well as is used in this case a biologically pure culture of the microorganism strain selected hirsuta, strain 367 (nrrl 12045, dsm 1886)

摘要

Novel antibiotic U-59,761 producible in a fermentation under controlled conditions using a biologically pure culture of the microorganism Saccharopolyspora hirsuta strain 367, NRRL 12045. This antibiotic is active against various microorganisms, for example, Staphylococcus aureus, Streptococcus pyogenes, Sarcina lutea, Klebsiella pneumoniae, Mycobacterium avium, and Bacteroides fragilis. Thus, antibiotic U-59,761 can be used in various environments to eradicate or control such bacteria.
