Abstract
Alkali-soluble glucan was obtained from Candida spec. H by extraction with dilute sodium hydroxide. This minor component is quite heterogeneous in molecular size, has a highly branched structure and contains 19% beta (1,3)-, 24% beta (1,6)- and only 2% beta (1,2)-linkages. Other minor polysaccharide components have been isolated by acetic acid extraction. They have been identified as glycogen and linear beta(1,6)-glucan, respectively. The major component is a 1,2-, 1,3,-, 1,6-glucan branched in 1,2,3-, 1,3,6- and 1,2,6-positions, containing chitin. So we can confirm that different yeasts may differ in glucan structures which vary considerably both in the degree of branching and molecular size.
