Abstract
Carbon-13 nuclear magnetic resonance spectra of several yeasts were measured as aqueous suspensions, and were compared with those of the yeast mannan and the glucan. The spectrum of Saccharomyces cerevisiae was quite similar to the sum of the spectra of the mannan and the glucan. The signals attributable to the mannan were stronger than those of the glucan. The spectra of other yeasts, such as Candida utilis, Candida pseudotropicalis, and Kluyveromyces fragilis were different from each other. The results suggest that (1) this approach may be useful for chemotaxonomical examination of yeasts, (2) mannan and glucan in the cell wall showed a mobility similar to that of the pure preparations.
