    摘要: A novel polysaccharide comprising (1->4) bonded α-D-glucose units represented by the following formula
    wherein R is a hydrogen atom or an acetyl group in the ratio of ca. 7:3 is extracted and isolated from a liquid culture medium of a microorganism belonging to the genus Basidiomycetes in the presence of a plant tissue raw material. About 30% by mole of hydroxyl groups at the 2,3-positions of each unit is acetylated and the polysaccharide has a molecular weight of 500 to 10,000. The polysaccharide has properties of biological response modifiers (BRM) and is useful as an immuno-enhancing agent or immuno-activator.
