Abstract :イエシロアリのアセトン分別酵素液を用いカルボキシメチルセルロース(CMC)および甘蔗バガス(砂糖きび絞り粕)に対する作用を調べ以下のような結果が得られた。1 CMCはシロアリセルラーゼで分解され還元糖の増加があった。反応液の酵素液濃度およびCMC濃度の増大にともない還元糖の増加がみられた。2シロアリセルラーゼのCMCに対する反応最適pHは4.5-5.5にあり, 反応最適温度は45℃であった。3シロアリセルラーゼはアルカリ処理バガスを分解して還元糖を生成するが, 熱水処理バガスはほとんど分解しなかった。
These experiments were carried out to investigate the decomposition of carboxymethyl-cellulose (CMC) and sugarcane bagasse by the termite cellulase preparation which was extracted from termites (Coptotermes formosanus), and then fractionated with aceton. The results obtained were as follows : 1) CMC was decoposed by the termite cellulase preparation, increasing in the reducing sugar. With increasing concentration of the enzyme solution and CMC of the enzyme reaction mixture, the amount of the reducing sugar increased. 2) The optimal pH of the termite cellulase activity for the decomposition of CMC as substrate was in a range of pH from 4.5 to 5.5,and the optimal temperature was 45℃. 3) Alkali treated bagasse was decomposed by the enzyme preparation, increasing in the reducing sugar. However, heat water treated bagasse was hardly decomposed.
