Abstract
Disclosed herein are materials such as a coating, comprising a lipolytic enzyme or organophosphrous compound degrading enzyme. Also disclosed herein are methods of visually detecting enzyme activity in a coating by contacting the coating with a substrate of an enzyme and a visual indicator that changes appearance upon production of a product of enzyme activity on a tack-free coating surface.

1-20. (canceled)
A composition for promoting lipid removal comprising:
- a coating material;
- and
- a lipase capable of degrading a lipid component, said lipase associated with said coating material so as to be capable of promoting lipid removal when said coating material is contacted by a lipid.
A composition for promoting surface contaminant removal comprising:
- a coating material;
- and
- a lipase capable of degrading a surface contaminant component, said lipase associated with said coating material so as to be capable of promoting surface contaminant removal when said coating material is contacted by a surface contaminant.
A composition for promoting lipid removal comprising:
- a surface;
- and
- a lipase capable of degrading a lipid component, said lipase associated with said surface so as to be capable of degrading a lipid contacting said surface;
- and
- a lipid, said lipid contacting said surface and said lipase.
A composition for promoting surface contaminant removal comprising:
- a surface;
- and
- a lipase capable of degrading a surface contaminant component, said lipase associated with said surface so as to be capable of degrading a surface contaminant contacting said surface;
- and
- a surface contaminant, said surface contaminant contacting said surface and said lipase.
A curable composition for promoting lipid removal comprising:
- a lipase;
- and
- a solvent-borne two-component polyurethane coating material;
- said lipase dispersed into said coating by covalent interaction with said coating material so as to be capable of degrading a lipid when said coating is contacted by a lipid.
A curable composition for promoting surface contaminant removal comprising:
- a lipase;
- and
- a solvent-borne two-component polyurethane coating material;
- said lipase dispersed into said coating by covalent interaction with said coating material so as to be capable of degrading a surface contaminant when said coating is contacted by a surface contaminant.
