Japanese Patent JP2009504131
Kind Code:
A
Abstract:
The present invention relates to an dihydroxy-acid dehydratase gene and use thereof, in particular, a brewery yeast for producing alcoholic beverages having 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 level of producing total vicinal diketones, especially level of producing diacetyl, that are responsible off-flavor of the product, is reduced by amplifying the expression level of ILV3 gene encoding brewery yeast dihydroxy-acid dehydratase ILV3p, particularly non-ScILV3 gene specific to lager brewing yeast, and to a method for producing alcoholic beverages with said yeast.
