Patent number: 10294497Abstract: An object of the present invention is to obtain fermentative yeast having highly efficient ethanol production without introducing a foreign gene. A further object is to obtain a fermentative yeast that is resistant to proliferation inhibitors such as organic acids, which prevent the proliferation of the fermentative yeast. Meyerozyma guilliermondii that can produce ethanol effectively from pentose and hexose was isolated by breeding. Moreover, resistance was imparted to the fermentative yeast by introducing transaldolase and alcohol dehydrogenase genes derived from Meyerozyma guilliermondii into the fermentative yeast.Type: GrantFiled: December 5, 2014Date of Patent: May 21, 2019Assignee: HONDA MOTOR CO., LTD.Inventors: Yoshiki Tsuchida, Norihiko Tsukagoshi, Ikumi Kurihara, Akihiko Aoyagi

Patent number: 10131917Abstract: An object of the present invention is to obtain a fermentative yeast having a highly efficient ethanol production without introducing a foreign gene. A further object is to obtain a fermentative yeast that is resistant to proliferation inhibitors such as organic acids, which prevent the proliferation of the fermentative yeast.

Patent number: 9732363Abstract: The present invention provides a growth method for a microbe which can enhance the growth of the microbe without removing growth inhibitors from a saccharified solution. The growth method for a microbe comprises the steps of: obtaining a mixed saccharified solution by diluting the saccharified solution containing a growth inhibitor which inhibits the growth of the microbe with a sugar solution having a smaller growth inhibitor concentration than that of the saccharified solution such that the growth inhibitor concentration is decreased; and allowing the microbe to grow by adding the microbe to the mixed saccharified solution.Type: GrantFiled: March 10, 2015Date of Patent: August 15, 2017Assignee: HONDA MOTOR CO., LTD.Inventors: Yoshiki Tsuchida, Norihiko Tsukagoshi, Masaki Ueyama

Publication number: 20130260365Abstract: In SSF, a highly efficient process for producing bioethanol is provided. Concentrations of an organic acid formed in a saccharified solution are measured from the initiation to completion of the saccharification, an average change rate of the organic acid concentrations is determined based on the organic acid concentration levels at respective time points, and the optimal timing of feeding a fermentative microorganism cell to the saccharified solution is determined using the average change rate as the indicator, whereby the fermentative microorganism cell is fed.Type: ApplicationFiled: March 8, 2013Publication date: October 3, 2013Applicant: HONDA MOTOR CO., LTD.Inventors: Kosuke Murata, Yoshiki Tsuchida, Naoki Ohta
