Óleo ou gordura ou biocombustível, método para redução da quantidade de esteril glicosídeo no dito óleo ou gordura e/ou um biocombustível, uso de uma ou mais enzimas em um dito óleo ou gordura, bem como composição enzimática

摘要

The present invention relates to a method for reducing the amount of steryl glycoside in an oil or fat (e.g. a biofuel substrate) and/or a biofuel, the method comprising admixing one or more enzymes with an oil or fat comprising steryl glycoside; such that said one or more enzymes degrades the steryl glycoside. The one or more enzymes is preferably an enzyme which is capable of hydrolysing the glycosidic bond in a steryl glycoside. Suitably the enzyme may be a glycosidase enzyme and/or a &bgr;-glucosidase and/or an amyloglucosidase.
