Tween系界面活性剤によるβ-アミラーゼ阻害に関する研究(第1報) : Tween系界面活性剤水溶液貯蔵中の変化

抄録

Activity of β-amylase was not changed by the addition of newly prepared aqueous solution of nonionic detergents such as Tween, Span, and others. Tweens, especially Tween 80, had inhibitory action on β-amylase when the solution is stored over a long period. Tweens were hydrolyzed during storage and the fatty acids liberated from Tweens had inhibitory action on the enzyme. Hydrolyzate from Tween 80 by the action of lipase produced from Rhizopus delemar had no inhibitory action on β-amylase. Therefore, there seems to be a difference in the mechanism of hydrolysis of Tween solution between that produced by storage and that due to lipase added.
