Patent

CA 2638835

The present invention relates to an acetolactate synthase gene and use thereof, in particular, a brewery yeast for producing alcoholic beverages with superior flavor, alcoholic beverages produced with said yeast, and a method for producing said beverages. More particularly, the present invention relates to a yeast, whose capability of producing vicinal diketones, especially diacetyl, that are responsible for off-flavors in products, is reduced by repressing expression level of ILV2 gene encoding an acetolactate synthase (Ilv2p), especially non-ScILV2 gene specific to a lager brewing yeast, and to a method for producing alcoholic beverages with said yeast.

La présente invention concerne un gène d'une acétolactate synthase et l'utilisation dudit gène, en particulier une levure de bière servant à produire des boissons alcoolisées à flaveur supérieure, des boissons alcoolisées produites à l'aide de cette levure et un procédé de production desdites boissons. Cette invention concerne plus particulièrement une levure dont la capacité de production de dicétones vicinales, notamment de diacétyle, qui sont responsables de flaveurs atypiques dans des produits, est réduite par répression du niveau d'expression du gène ILV2 codant pour une acétolactate synthase (Ilv2p), notamment du gène ILV2 non Sc spécifique à une levure de bière de fermentation basse, ainsi qu'un procédé de production de boissons alcoolisées à l'aide de ladite levure.
