Patent number: 8048667Abstract: 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.Type: GrantFiled: September 9, 2008Date of Patent: November 1, 2011Assignee: Suntory Holdings LimitedInventors: Haruyo Hatanaka, Fumihiko Omura

Publication number: 20080032386Abstract: 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.Type: ApplicationFiled: June 17, 2005Publication date: February 7, 2008Inventors: Fumihiko Omura, Nobuyuki Fukui, Hiroto Kondo

Patent number: 6753964Abstract: 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.Type: GrantFiled: December 5, 2001Date of Patent: June 22, 2004Assignee: Ulvac, Inc.Inventors: Kai Chen, Fumihiko Omura, Akihito Minamitsu, Shizuo Nakamura
