title: Structural elucidation of fungal polysaccharides isolated from the cell wall of Plectosphaerella cucumerina and Verticillium spp.
abstract: The structure of acidic fungal polysaccharides isolated from the cell wall of Plectosphaerella cucumerina, Verticillium dahliae, and V. albo-atrum has been investigated by chemical analysis, methylation analysis, and 1D and 2D 1H and 13C NMR spectroscopy. The polysaccharides have an idealized repeating block of the type: [carbohydrates: see text] linked to a small mannan core (<15%), where n=13, m=13, p=5, and q=8 for P. cucumerina, and n=16, m=16, p=6, and q <1 for both Verticillium species.
