内容記述 64株のカビをフスマーバガス培地に培養して得られる麹抽出液を酵素液としてバガス分解活性を調べた結果, Aspergillus niger AUR 3124が比較的高い活性を有することがわかった。本菌株が生産する酵素によるバガスセルロースの分解性とバガスの前処理との関係を調べた。バガスセルロースの分解性は, 水酸化ナトリウム, 次亜塩素酸ナトリウム及びエチレンジアミン処理することにより著しく高められた。バガスセルロースの分解率は, バガスを処理する水酸化ナトリウム及び次亜塩素酸ナトリウムの濃度に依存した。本酵素によるバガス分解性を高めるためバガスセルロースの分解性からみたバガスの前処理法は水酸化ナトリウムによる処理が適当であった。Asp.niger AUR 3124菌株セルラーゼの反応の至適pH及び温度はそれぞれ4.0∿4.5,40℃であった。
