Abstract
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.
Claims12
A method of facilitating the removal of a biological stain containing a protein component on a substrate or a coating comprising:
- providing a liquid coating material;
- associating an active extracellular portion of bacterial neutral thermolysin-like protease from Geobacillus stearothermophilus with said liquid coating material to form a liquid bioactive coating material at a pH of 10.0 to 11.0, such that said protease is capable of enzymatically degrading a protein component of a biological stain, wherein said protease has a specific activity in excess of 20,000 U/g in said liquid bioactive coating material.
A liquid bioactive coating material for facilitating removal of a biological stain containing a protein component comprising:
- a liquid coating material;
- and
- an active extracellular portion of bacterial neutral thermolysin-like protease from Geobacillus stearothermophilus, said protease capable of degrading a biological stain containing a protein component wherein said protease is associated with said liquid coating material,
- wherein the liquid bioactive coating material has a pH of 10.0 to 11.0, wherein said protease has a specific activity in excess of 20,000 U/g in said liquid bioactive coating material.
