| 摘要 |
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.
