  • Microorganism having carbon dioxide fixation pathway introduced thereinto
    Patent number: 9822387
    Abstract: An acetyl-CoA-producing microorganism, which is capable of efficiently synthesizing acetyl-CoA using carbon dioxide, and a substance production method using the same are provided. An acetyl-CoA-producing microorganism including an acetyl-CoA production cycle obtained by imparting at least one type of enzymatic activity selected from the group consisting of malate thiokinase, malyl-CoA lyase, glyoxylate carboligase, 2-hydroxy-3-oxopropionate reductase, and hydroxypyruvate reductase, to a microorganism.
    Type: Grant
    Filed: July 27, 2012
    Date of Patent: November 21, 2017
    Assignee: MITSUI CHEMICALS, INC.
    Inventors: Ryota Fujii, Tomokazu Shirai, Tadashi Araki, Koh Amano, Yoshiko Matsumoto, Toshihiro Tateno, Nozomi Takebayashi, Takashi Morishige, Hitoshi Takahashi, Mitsufumi Wada, Hiroshi Shimizu, Chikara Furusawa, Takashi Hirasawa, Tomonori Hidesaki, Ayako Endo, Dominik Lukas Jürgen-Lohmann, Anjali Madhavan, Su Sun Chong
  • Isopropyl alcohol-producing bacterium having improved productivity by GntR destruction
    Patent number: 9267156
    Abstract: An isopropyl alcohol-producing Escherichia coli includes an isopropyl alcohol production system, wherein an activity of transcriptional repressor GntR is inactivated, and the isopropyl alcohol-producing Escherichia coli preferably further includes a group of auxiliary enzymes having an enzyme activity expression pattern with which isopropyl alcohol production capacity achieved by the inactivation of the GntR activity is maintained or enhanced. A method of producing isopropyl alcohol includes producing isopropyl alcohol from a plant-derived raw material using the isopropyl alcohol-producing Escherichia coli. A method of producing acetone includes contacting the isopropyl alcohol obtained by the isopropyl alcohol production method with a complex oxide that includes zinc oxide and at least one oxide containing a Group 4 element, and that is prepared by coprecipitation.

  • Highly productive isopropyl alcohol-producing bacterium
    Patent number: 8932845
    Abstract: An isopropyl alcohol-producing Escherichia coli equipped with an isopropyl alcohol production system, having at least one enhanced enzyme activity selected from the group consisting of an enhanced malate dehydrogenase activity, an enhanced NAD(P)+ transhydrogenase (AB-specific) activity, and an enhanced thiolase activity, and an isopropyl alcohol producing method including producing isopropyl alcohol from a plant-derived raw material using the isopropyl alcohol-producing Escherichia coli.
