    Abstract:
    The mannans of Saccharomyces chevalieri, S. italicus, S. diastaticus, and S. carlsbergensis, were acetolyzed, and the fragments were separated by gel filtration. All gave similar acetolysis fingerprints, which were distinguished from S. cerevisiae by the presence of a pentasaccharide component in addition to the mono-, di-, tri-, and tetrasaccharides. All oligosaccharide fragments were composed of mannose in alpha-linkage. From methylation analysis and other structural studies, the disaccharide was shown to be alphaMan(1 --> 2)Man; the trisaccharide was shown to be a mixture of alphaMan(1 --> 2)alphaMan (1 --> 2)Man and alphaMan(1 --> 3)alphaMan(1 --> 2)Man; the tetrasaccharide was alphaMan(1 --> 3)alphaMan(1 --> 2)alphaMan(1 --> 2)Man; and the pentasaccharide was alphaMan(1 --> 3)alphaMan(1 --> 3)alphaMan(1 --> 2)alphaMan(1 --> 2)Man. The ratios of the different fragments varied slightly from strain to strain. Mannanase digestion of two of the mannans yielded polysaccharide residues that were unbranched (1 --> 6)-linked polymers, thus establishing the structural relationship between these mannans and that from S. cerevisiae. Antisera raised against the various yeasts cross-reacted with the mannans from each, and also with S. cerevisae mannan. The mannotetraose and mannopentaose acetolysis fragments gave complete inhibition of the precipitin reactions, which indicated that, in these systems as in the S. cerevisiae system, the terminal alpha(1 --> 3)-linked mannose unit was the principal immunochemical determinant on the cell surface.
