The present invention relates to a gene encoding trehalose-6-phosphate phosphatase and use thereof, in particular, a yeast for practical use with superior resistance property to dryness and / or low-temperature storage, alcoholic beverages produced with said yeast, and a method for producing said beverages. More particularly, the present invention relates to a yeast, whose resistance property to dryness and / or resistance property to low-temperature storage is enhanced by amplifying expression level of TPS2 gene encoding a trehalose-6-phosphate phosphatase Tps2p in brewer's yeast, especially non-ScTPS2 gene specific to a lager brewing yeast and to a method for producing alcoholic beverages with said yeast, etc.

The invention relates to a method for embedding lactic acid bacteria by using Maillard products as wall materials, and belongs to the technical field of protection of lactic acid bacteria. The method is to fully dissolve the protein and carbohydrates, react at 60-90°C for 30-60min, make the mixed solution appear yellowish brown, then disperse the lactic acid bacteria concentrate in the mixed solution, and spray dry to obtain lactic acid bacteria with high stability Good bacteria powder. The protein is selected from casein, whey protein, soybean protein, egg white protein or protein hydrolyzate, and the carbohydrate is composed of reducing sugar and prebiotic sugar in equal weight ratio. The powder obtained by the invention can effectively improve the survival rate of lactic acid bacteria in the spray drying process, storage period and human digestive tract, and is easy to implement and low in cost.

The invention discloses a lactic acid bacterium or yeast porous starch embedding and protecting method. Lactic acid bacteria or yeasts are cultured in a fermentation tank with high density to make the total amount of the lactic acid bacteria in a fermentation liquor reach 3.4 to 4.5 * 10<9>CFU / mL and the total amount of the yeasts reach 2 to 3 * 10<10>CFU / mL; the fermentation liquor is concentrated by 15 to 20 times in vacuum to obtain a concentrated bacterial liquid; porous starch, dried whey and trehalose are added into the concentrated bacterial liquid; and after being uniformly stirred until the mixture is pasty, the mixture is dried to obtain a product with relatively high viable bacteria content. The amount of the viable bacteria in the lactic acid bacterium or yeast embedding preparation produced by the technique is over 10<10>CFU / g; the product is resistant in storage; the production process is simple; and the cost is low.

The present invention relates to a gene encoding glycogen synthase and use thereof, in particular, a yeast for practical use with superior resistance property to dryness and / or low-temperature storage, alcoholic beverages produced with said yeast, and a method for producing said beverages. More particularly, the present invention relates to a yeast, whose resistance property to dryness and / or resistance property to low-temperature storage is enhanced by amplifying expression level of GSY1 or GSY2 gene encoding a Gsy1p or Gsy2p which is a glycogen synthase in brewer's yeast, especially non-ScGSY1 gene or non-ScGSY2 gene specific to a lager brewing yeast and to a method for producing alcoholic beverages with said yeast, etc.
