This study was performed to obtain higher yield rate of protein-bound polysac-charide extracted from cultured broth and fruit body of Coriolus versieolor, basidiomycetes. 16002 strain produced 0.58%, the highest yield rate among four strains, and there was no significantly different yield in other three strains. The optimal liquid media were CVT-III to obtain higher yield of protein-bound polysaccharide comparing with the various culture media. Compared with several materials for substitution of medium source, the residue extract media of Coriolus versieolor fruit-body were yield rate similar to control, and addition of the extracts of ginseng residues increased 11.4-48%. And also compared with fruit bodies that were artificially cultured on the oak longs, 16002 strain produced the highest yield similar to the result of cultured broth. Fruit body of the prematures stage was more effective to obtain high yield rate.
