Abstract
An antibiotic complex consisting of 4 components, seldomycin factors 1, 2, 3 and 5 was isolated from the fermentation broth of Streptomyces hofunensis by use of a cationic exchange resin. After silica gel column chromatography, the purified components were characterized as new aminoglycoside antibiotics by their physicochemical, chromatographic and antimicrobial properties.
