Abstract
A method of increasing loading of active enzyme immobilized in a polyurethane polymer including the steps of: synthesizing the polyurethane polymer in a reaction mixture containing water and enzyme; and including a sufficient amount of a surfactant in the reaction mixture to increase enzyme activity at an enzyme loading.
Claims8
A method of increasing loading of active enzyme immobilized in a polyurethane polymer, the method comprising the steps of:
- synthesizing the polyurethane polymer in a reaction mixture containing water and enzyme wherein an enzyme loading of the polyurethane polymer is greater than approximately 0.5 percent by weight of the polyurethane polymer;
- and
- including a sufficient amount of a surfactant in the reaction mixture to increase enzyme activity at the enzyme loading.
