Abstract

Abstract Lipase is derived from Humicola sp. (incl. Thermomyces sp. ), preferably H. lanuginosa . This lipase is found to have high activity at alkaline pH and to be compatible with anionic surfactants, and it is more effective as a detergent additive than prevously described detergent lipases.
