Abstract:
A process for the preparation of long-chain alkyl glycosides, comprising reacting at least one substrate selected from a group consisting of carbohydrates and carbohydrate sources and at least one fatty alkanol of at least eight carbon atoms in a medium comprising at least one glycosidase enzyme having a temperature optimum greater than 60.degree. C. and having thermal stability half-life of greater than 24 hours at 80.degree. C., wherein said enzyme is characterised by the ability of 0.05 mg of said enzyme to catalyze a reaction between 750 mg dodecanol and 50 mg of beta methyl glycoside at 80.degree. C. to achieve a rate of dodecyl glycoside formation of at least 20 micromole per day per mg of the enzyme.
