Novel compounds, called chloropolysporins B and C, and salts thereof have antibiotic properties and would appear to be members of the class of glycopeptide antibiotics containing chlorine. They may be produced by cultivating a suitable strain of miroorganism of the genus Micropolyspora, especially Micropolyspora sp. SANK 60983 (FERM BP-538). They may be combined with conventional pharmaceutically acceptable carriers or diluents for therapeutic use or incorporated into edible excipients, such as feed or water, for use as a growth-promoting agent, especially for farm animals.
