  • Alcoholic fermentation yeast and method for producing ethanol using same
    Patent number: 9617565
    Abstract: [Problem] To provide an alcoholic fermentation yeast having resistance to limonene, which is a fermentation inhibitor, and a method for producing ethanol using the alcoholic fermentation yeast. [Solution] An alcoholic fermentation yeast Saccharomyces cerevisiae (Deposition No. NITE BP-890), which has resistance to limonene and can grow in the presence of limonene at a concentration of 0.1-0.5 wt %, and a method for producing ethanol using the alcoholic fermentation yeast.
    Type: Grant
    Filed: November 12, 2014
    Date of Patent: April 11, 2017
    Assignees: NIPPON STEEL & SUMIKIN ENGINEERING CO., LTD., EHIME PREFECTURE
    Inventors: Natsuki Maekawa, Yasuhiko Katoh, Takafumi Kiuchi, Praneetrattananon Suthasinee, Shinji Okamoto, Kazuko Hirayama, Syunsuke Miyaoka, Hideaki Tadanobu, Masahiko Sudo
  • Device for producing ethanol and method for producing ethanol
    Patent number: 9308469
    Abstract: Disclosed are a method for producing ethanol and a device for producing ethanol that are suitable to the recycled use of an enzyme. The device is configured from: a vacuum distillation tower (11) into which an ethanol-fermented liquid generated by saccharification fermentation of a biomass starting material is introduced, and with the interior in a state that is at a lower pressure than atmospheric pressure, that subjects the ethanol-fermented liquid to distillation, distilling ethanol vapor that contains water vapor, and removing as a bottom product the enzyme-containing concentrated waste liquid that is roused for saccharification fermentation of the biomass starting material; and a fractionating tower (12) for fractionating the ethanol vapor distilled from the vacuum distillation tower (11).
