  • Patent number: 9695461
    Abstract: The stabilization of a hydrolytic enzyme in a liquid preparation is to be improved through a component that stabilizes the hydrolytic enzyme. This is accomplished by a method for adapting a hydrolytic enzyme to a component that stabilizes the hydrolytic enzyme, comprising the following method steps: a) providing a hydrolytic enzyme (starting enzyme) and a component that stabilizes the hydrolytic enzyme and that comprises a reversible inhibitor of the hydrolytic enzyme; b) changing the amino acid sequence of the hydrolytic enzyme in at least one position, by substitution, deletion or insertion; c) determining the relative activity of the hydrolytic enzyme from step b) and the relative activity of the starting enzyme in a liquid preparation; d) selecting the hydrolytic enzyme that has a reduced relative activity by comparison with the relative activity of the starting enzyme.

  • Publication number: 20110136720
    Abstract: A washing or cleaning process includes the step of preparing a washing or cleaning solution that includes a washing or cleaning agent including a hydrolytic enzyme, and a component that, by interacting with the hydrolytic enzyme when the agent is used, affects a synergistic cleaning power. The component may be an anionic and/or polyanionic substance, a cationic and/or polycationic substance, and/or a substance that possesses hydroxyl and/or polyhydroxyl group(s). The process then includes the step of contacting a textile or a hard surface with the washing or cleaning solution.
