The water-soluble cell-wall polysaccharides isolated from strains CBS 352.72 and 310.38 of Talaromyces j7avus have been investigated by chemical analyses and NMR studies. Two different skeletons coexist, having the structures: [ -6) -P-D-Galf-(1 -D 5)+-D-Galf-(1 + 1, 2 1 a-D-Glcp-(1 -+ 2)-o-n-Galf a

✦ Synopsis
The structure of two cell-wall polysaccharides isolated from three different strains of Penicillium expansum, the type species of the genus, have been established by 1D and 2D NMR spectroscopy, and also by methylation analyses. The water-soluble polysaccharide F1S-B consisted of a linear tetrasaccharide repeating unit with the following structure: [-->6)-beta-D-Galf-(1-->5)-beta-D-Galf-(1-->5)-beta-D-Gal f-(1-->5)-beta-D- Galf-(1-->]n The alkali-soluble polysaccharide F1I is a (1-->3)-alpha-D-glucan.
