Saccharomyces rouxii

Mannans of Hansenula capsulata Y-1842 and H. holstii Y-2448 differ structurally from the phosphonomannan components.83 The man-nan of H. capsulata is probably a cell-wall component, and it has the linear, repeating-structure 6. Other Pichia and Hansenula mannans have predominantly linear structures.84 The 13C-n.m.r. spectrum of 6 (see Fig. 2) is distinguishable from that of the branched-chain man-nan85 from Saccharomyces rouxii (repeating unit 7.)... 

The interaction between con A and a-mannans from a variety of micro-organisms was studied by So and Goldstein.204 The mannans from Saccharomyces cerevisiae, Saccharomyces rouxii, and Sarcina sp., and the phosphomannan from Saccharomyces pini Y-2579, all gave classical precipitin curves similar to those obtained for dextrans,320,362 but unlike the extended curves given by glycogen.369 A synthetic, linear (1—>3)-a-D-mannopyranan did not precipitate204 with con A.

The ability of yeasts to utilize sugars is not only of potential value it can also be a nuisance.25,26 Yeasts are notorious as spoilers of foods that contain a high concentration of one or more sugars, such as honey, maple syrup, sugar cane, and confectionery. The capacity of the yeasts Saccharomyces bisporus and Saccharomyces rouxii to ferment honey,27,28 which is composed of 70 to 80% of hexoses,29 is a feat of outstanding physiological interest in view of the remarkably high osmotic forces which the yeasts must withstand.30-32... 

Correspondingly, yeasts of different species utilize different parts of the rafflnose molecule,571 or none. The following examples of each kind of utilization for species of Saccharomyces come from Reference 64. (i) Neither Saccharomyces bisporus nor Saccharomyces rouxii utilizes rafflnose. (it) Saccharomyces cerevisiae and Saccharomyces fermentati can each utilize solely the D-fruc-tofuranosyl group of rafflnose after the initial action of /3-D-fruc-tofuranosidase. (Hi) Saccharomyces oleaginosus (italicus var.

Saccharomyces rouxii mannan. Gorin and Perlin have established that the main slime polysaccharide produced during the fermentation of this yeast is a mannan. The marman ([a] +53 ) on acetolysis gave a mixture of acetates which were deacetylated to the parent oligosaccharides. A. disaccharide so isolated was shown to be 2-0-a-D-mannopyranosyl-D-mannose by methylation and isolation of 2,3,4,6-tetra-O-methyl-D-mannose and...
