摘要:
The present invention relates to a glucose-induced inactivation/degradation-resistant transporter gene and use thereof, and more particularly, to a brewing yeast having excellent assimilation of oligosaccharides (maltose, maltotriose, etc.), an alcoholic beverage prepared using the yeast, a method of producing the alcoholic beverage, etc. More specifically, the present invention relates to a glucose-induced inactivation/degradation-resistant transporter including Mal21p, mutant Mal31p, mutant Mal61p, mutant Mtt1p, mutant Agt1p, etc., a gene encoding the transporter, a method of producing an alcoholic beverage using thereof, and so on.

The present invention relates to a glucose-induced inactivation/degradation resistant transporter gene and use thereof, and more particularly to a brewery yeast having excellent assimilability of oligosaccharides (maltose, maltotriose, etc.), an alcoholic beverage produced using the yeast, and so on. In particular, the present invention relates to a glucose-induced inactivation/degradation resistant transporter such as Mal21p, etc., a gene encoding the same, a method of producing an alcoholic beverage using the same; and so on.
摘要:
The present invention relates to alpha-glucoside transporters which can promote assimilation of maltose/maltotriose contained in wort, etc., and so on. Especially in relation to glucose-induced inactivation/degradation, the present invention relates to alpha-glucoside transporters which are less susceptible to glucose-induced inactivation/degradation and can take up maltotriose like AGT1, by constructing the hybrid of AGT1 and MAL21. By using, e.g., a yeast expressing the alpha-glucoside transporter of the present invention, the fermentation rate of moromi mash containing oligosaccharides such as maltose/maltotriose can be accelerated.
摘要:
The present invention relates to the identification of alleles of the MET2 and SKP2 genes having the effect of reducing the production of sulphites, of hydrogen sulphide and of acetaldehyde by Saccharomyces, and to the use of these alleles in methods for controlling the production of these compounds during alcoholic fermentation.
摘要:
The present invention relates to modified industrial yeast strains that show reduced hydrogen sulfide production. In one embodiment the invention provides an industrial yeast strain comprising a modification in a MET5 gene and/or a MET10 gene which results in reduced hydrogen sulfide production when compared to the corresponding industrial yeast strain without the modification. The present invention also relates to methods of manufacturing these modified industrial yeast strains and their use in the production of fermented products.
摘要:
The present invention relates to a mutant acetohydroxy-acid reductoisomerase gene (mutant ILV5 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. According to the method for producing alcoholic beverages of the present invention, because of reduction of the production of VDKs, especially DA, which are responsible for off-flavors in products, alcoholic beverages with superior flavor can be produced.
摘要:
A method for the production of a stilbenoid, such as resveratrol or pinosylvin, by fermenting plant material such a grape must using a yeast having a metabolic pathway producing said stilbenoid, separating a solids waste material from said fermentation and extracting said stilbenoid.
摘要:
The invention relates to yeasts expressing the gene BDH1 coding for Bdh1p, characterised in that they catalyse, in an alcoholic fermentation medium, the reduction of acetoin into 2,3-butanediol by a rate at least twice higher than that of the initial stem. The invention can particularly be used for the fermentation of fruit juice and for producing 2,3-butanediol.
摘要:
The present invention relates generally to methods and compositions for enhancing the flavor or other properties of wine, and wine products produced by such methods.
摘要:
Provided herein are genetically modified yeast cells that recombinantly expresses a gene encoding a mutant beta-lyase. Also provided are methods of producing fermented products and methods of producing ethanol.
