Degradation of biologically degradable polymers using lipase from Candida antarctica and a cutinase

摘要

A method for the enzymatic degradation of biodegradable polymers, specifically polyester amides and polyester urethanes, contained in moldings, sheet-like products, coatings, adhesives or foams. The enzymes are selected from the lipase from Candida antarctica and cutinase, specifically Humicola insolens. The biodegradable polymer is treated with an aqueous solution, a mixture of alcohol and water, that is optionally buffered and contains the enzymes.
