| 摘要 |
This invention relates to three new antibiotics which are designated BM782 alpha 1, BM782 alpha 2, and BM782 alpha 1a, respectively, and 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 potentially useful for inhibiting the growth of such bacteria and bacilli. |
