Elbein , A. D. (Purdue University, Lafayette, Ind.) J. A. Holowczak, Henry Koffler, and H. R. Garner . Detection and ìsolation of new glycosides in culture broths of Streptomyces hygroscopicus . J. Bacteriol. 91: 604–608. 1966.—Four new compounds not previously reported have been isolated and purified from the culture broths of Streptomyces hygroscopicus . The data presented suggest that these compounds may be structurally related to hygromycin A, having similar aglycons but differing in their sugar moieties. Two of the compounds apparently contain d -glucose or l -fucose as their sugar components. The others, like hygromycin A, form crystalline 2,4-dinitrophenylhydrazones, and may contain unusual keto sugars.
