Abstract

The effect of cultural conditions on mycelial growth and fruit body-polysaccharide of Inonotus obliquus was studied. The optimum condition of mycelial growth was 30℃ and pH 7 on the PDA medium. Mannose, maltose, fructose and glucose were beneficial carbon sources for mycelial growth. Peptone, malt extract and yeast extract were favorable nitrogen sources. Formation of fruit body was success on sawdust substrate supplemented with rice bran or corn powder. Polysaccharide was formed well in fruit body grown on the rice bran media.
