Abstract : The proton magnetic resonance spectra of the mannans, galactomannans and mannose-containing heteropolysaccharides of a number of species of Candida were determined, and compared with the spectra of similar polysaccharides of some species of the sporogenous genera Pichia, Hansenula, Endomycopsis, Debaryomyces and Saccharomyces. Similarities among the spectra were used as an aid in classification. The Candida species studied were placed in four groups: (1) those Candida species classified as asporogenous forms of perfect species, (2) those which produce mannose-containing polysaccharides having p.m.r. spectra resembling those of the mannans of known perfect species, (3) members of the Candida parapsilosis group, (4) those Candida species which did not ferment glucose and which were not included in one of the other groups.
