Clearcoat containing thermolysin-like protease from <i>Bacillus stearothermophilus </i>for cleaning of insect body stains

摘要

A substrate or coating is provided that includes a protease with enzymatic activity toward a component of a biological stain. Also provided is a process for facilitating the removal of a biological stain is provided wherein an inventive substrate or coating including a protease is capable of enzymatically degrading of one or more components of the biological stain to facilitate biological stain removal from the substrate or said coating.

主权项

1. A composition for facilitating biological stain removal, wherein said biological stain comprises protein, said composition comprising:
a substrate or a coating formed of an organic cross linkable polymer resin; and a bacterial neutral thermolysin-like protease from Bacillus stearothermophilus having a specific activity not less than 1,600,000 U/g, said thermolysin-like protease associated with said substrate or said coating, wherein said association is selected from the group consisting of: covalent attachment to said substrate or coating, non-covalent adherence to said substrate or coating and being admixed into said substrate or coating.
