Several extracellular glucans have been isolated from Phytophthora parasitica Dastur, a phytopathogenic fungus of the carnation. These polysaccharides consist of a mixture of (1-->3)(1-->6)-beta-D-glucans whose molecular masses varied from 1 x 10(4) to 5 x 10(6) Da. All of these polysaccharides have a main chain of beta-(1-->3)-linked D-glucose residues substituted with mono-, di- and oligo-saccharidic chains attached through (1-->6) linkages.
