Antibiotic A42125, which is produced by a new strain of Nocardia aerocolonigenes, NRRL 18049, is a useful inhibitor of Gram-positive and methane-generating microorganisms. A42125 also increases feed utilization efficiency in ruminants. A biologically purified culture of N. aerocolonigenes NRRL 18049 and a method for producing A42125 by fermentation of this culture are provided.
