Patent

CA 2177997

A method for stabilizing an enzyme against decomposition at elevated temperatures or by water is described which comprises combining the enzyme with stabilizing amounts of a non-ionic polyether-polyol block-copolymer surfactant. Stabilized compositions based on the enzyme and surfactant are also described.

Procédé de stabilisation d'une enzyme afin d'en prévenir la décomposition à des températures élevées ou par l'eau, consistant à combiner l'enzyme avec un tensioactif à base d'un copolymère séquencé de polyéther-polyol non ionique en une quantité stabilisatrice. Des compositions à base de ladite enzyme et du tensioactif sont également décrites.
