Abstract カバノアナタケの菌糸生長に対する培養条件を検討し,子実体を誘起した。さらに子実体の機能性成分として知られる多糖類の含有量と培地添加物の相関を検討した。生育特性を検討した結果,温度は30℃,pHは7,炭素源はグルコース,フルクトース,マンノース,マルトース,窒素源はイーストエキス,モルトエキス,ペプトンで菌糸の生長が良好であった。次いで,米ヌカまたはコーンパウダーを加えた木粉培地で子実体の形成を検討...した。その結果,米ヌカ培地で発生した子実体中に多糖類が多く含有されることが明らかになった。
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.
