Patent ID: 11939557
Assignee: DANSTAR FERMENT AG
Field: Biotechnology (Chemistry)
Classification: CPC C  Y | IPC C

Claim 0:
1. A recombinant yeast host cell for improving a flavor profile of a fermented beverage by hydrolyzing a non-volatile conjugate, wherein the fermented beverage is obtained by fermentation of a fermentable medium with the recombinant yeast host cell, and the non-volatile conjugate is of formula (I):

VFC—SM   (I)

where: VFC is a flavor compound that is volatile when released from the non-volatile conjugate,
SM is a sugar molecule, and
“—” is a β-glycosidic linkage covalently attaching the VFC to the SM, and capable of being hydrolyzed;, wherein the recombinant yeast host cell:
has a heterologous nucleic acid molecule encoding one or more heterologous polypeptide having 1,4-β-glucosidase activity for hydrolyzing the β-glycosidic linkage to release the VFC from the non-volatile conjugate;
has a native ethanol production pathway; and
is a brewing or wine strain.
