Hydrolysis of grape monoterpenyl glycosides by <i>Candida molischiana</i> and <i>Candida wickerhamii</i> β‐glucosidases

Abstract

Abstract The exocellular β‐glucosidases of Candida molischiana and Candida wickerhamii are able to hydrolyse geranyl, neryl, citronellyl, linalyl and α‐terpinyl‐β‐ D ‐glucopyranosides. The nature of the aglycone residue greatly affects the rate of hydrolysis. Glucosides with a tertiary alcohol as aglycone residue are more slowly hydrolysed than those with a primary alcohol. The β‐glucosidase from C molischiana is also able to hydrolse α‐L‐arabinofuranosides. This results in the release of monoterpenols from a glycoside extract from grape juice.
