Structural studies on the major, capsular polysaccharide from Cryptococcus bacillisporus serotype B.
The capsular material from Cryptococcus bacillisporus serotype B has been separated into essentially two fractions. One of these (60% of the total) has been studied by the methods usual for the structural elucidation of polysaccharides. The results are consistent with a structure having nonreducing D-xylosyl as well as D-glucosyluronic acid groups attached to O-2 of D-mannosyl residues linked alpha-(1 leads to 3) in a linear backbone. Every third D-mannosyl residue is doubly substituted with a D-xylosyl group at O-2 and a D-glucosyluronic acid group at O-4.
