Abstract
Abstract Novel antibiotic U-61,732 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 gram-positive bacteria, for example, Staphylococcus aureus. Also disclosed are the 11-acyl esters of U-61,732. Thus, these compounds can be used in various environments to eradicate or control such bacteria.
