Abstract: Methods for treating surfaces with lipase to provide an enzyme-surface complex and surfaces so treated facilitate oil removal. One such treated surface is a fabric with lipase sorbed onto the surface. A preferred sorbed lipase is isolatable from a Pseudomonas organism or clone. Treated fabrics have substantial hydrolysis activity for oil stains and perhydrolytic activity for oil stains, have altered surface wettability, and retard oil and hydrolysis by-produce redisposition in the presence of aqueous solutions. The sorbed lipase is resistant to removal during fabric laundering and retains substantial hydrolytic activity even with exposure to drying at elevated temperature. The hydrolytic activity of the lipase-fabric complex persists during storage or wear. Hydrolysis by-products are removable during laundering at basic pH or in the presence of surfactant.
