Abstract
Bioactive coatings that include a base and a protein associated with the base for actively promoting the removal of organic stains are provided. In aspects, bioactive coatings that are stabilized against inactivation by weathering are provided including a base associated with a chemically modified enzyme, and, optionally a first polyoxyethylene present in the base and independent of the enzyme. The coatings are optionally overlayered onto a substrate to form an active coating facilitating the removal of organic stains or organic material from food, insects, or the environment.
Claims12
A method of facilitating removal of an organic stain from a substrate or coating comprising:
- providing a substrate or coating formed of an organic crosslinkable polymer resin;
- associating a lipase with said substrate or said coating, said lipase capable of enzymatically degrading a component of an organic stain, wherein said lipase is uniformly dispersed in said substrate or said coating in protein aggregates having an average diameter of 10 micrometers or less;
- and
- facilitating removal of an organic stain from said substrate or said coating by rinsing.
