  • Patent number: 4375462
    Abstract: Antibiotic A-32724 complex, comprising microbiologically-active, related factors A, B and C, is produced by submerged, aerobic fermentation of a strain of Chaetomella raphigera Swift NRRL 12331. The A-32724 antibiotics are closely related antibiotics. The individual A-32724 factors are separated by chromatography. In addition to their antibacterial activity, the A-32724 factors inhibit certain enzymes and exhibit antihypertensive properties.
