Antibacterial antibiotic BM782

摘要

This disclosure describes three new antibiotics designated BM782 alpha 1, BM782 alpha 2, and BM782 alpha 1a which are produced in a microbiological fermentation under controlled conditions using a new strain of an undetermined species of the genus Nocardia or mutants thereof. These new antibacterial agents are active against Mycobacterium tuberculosis as well as both gram-positive and gram-negative microorganisms and thus are useful for inhibiting the growth of such bacteria and bacilli wherever they may be found.
