Abstract:

The proton magnetic resonance spectra of the mannose-containing polysaccharides of 42 Torulopsis species were determined and used as a basis for placing these species in seven groups. Five of the groups consisted of species which formed mannose-containing polysaccharides with spectra whose H-1 regions were like those of the mannans and galactomannans of species of Saccharomyces, Pichia, Hansenula, Debaryomyces or Metschnikowia. The sixth group consisted of Torulopsis bombicola, Torulopsis apicola and a number of other yeasts which were mostly sugar- and salt-tolerant. The seventh group consisted of species whose mannose-containing polysaccharides had spectra unlike those in the preceding groups. Some of the spectra had similarities to those of the mannose-containing polysaccharides of a miscellany of yeast species. Author
