Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to a gene encoding a catalase and use thereof, in particular, a brewery yeast having high sulfite-producing capability, 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 sulfite, that contribute to stability of flavor in products, is enhanced by amplifying expression level of CTT1 gene encoding a catalase Ctt1p, especially non-ScCTT1 gene or ScCTT1 gene specific to a lager brewing yeast, and to a method for producing alcoholic beverages with said yeast.

Abstract: The present invention relates to a gene encoding a protein having a vicinal diketone or diacetyl-reducing activity 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.

Abstract: The present invention relates to a stabilized proline transporter Put4 obtained by gene mutation and a gene encoding the same, as well as a Saccharomyces yeast strain which is obtained by yeast transformation with the gene and is capable of efficiently using proline in a source material such as wort. The stabilized mutated proline transporter Put4 can be used to achieve efficient use of nitrogen sources such as poorly assimilable proline contained in source materials (e.g., wort) for alcohol beverages. Fermentation using yeast capable of taking up a wide variety and large amounts of nitrogen sources facilitates carbon source assimilation and allows improvement of productivity for alcohol beverages. Moreover, the use of poorly assimilable nitrogen sources leads to resource savings and enables environmentally friendly production of alcohol beverages.

Abstract: A film-thickness measurement apparatus of the present invention includes a lifter, a support mount, a light-emitting device, and a light-receiving device. With the center of a wafer staying in alignment with that of the support mount, the lifter places the wafer onto the surface of the support mount to determine the center of the wafer. While the wafer is being rotated about the center of the wafer, the light-emitting device irradiates the circumferential portion of the wafer with a laser beam, thereby allowing the position of a notch to be detected depending on whether or not the laser beam passes through the notch. This makes it possible to detect the positions of the notch and the center of the wafer to determine the center axis line of the surface of the wafer, thereby allowing the coordinates of a given position on the surface of the wafer to be defined in accordance with the center axis line and the center of the wafer.
