  • Bacterium producing L-glutamic acid and method for producing L-glutamic acid
    Publication number: 20100124777
    Abstract: L-Glutamic acid is produced by culturing a coryneform bacterium having L-glutamic acid producing ability, in which trehalose synthesis ability is decreased or deleted by, for example, disrupting a gene coding for trehalose-6-phosphate synthase, a gene coding for maltooligosyltrehalose synthase, or both of these genes to produce and accumulate L-glutamic acid in the medium, and collecting the L-glutamic acid from the medium.
    Type: Application
    Filed: April 19, 2007
    Publication date: May 20, 2010
    Applicant: Ajinomoto Co., Inc.
    Inventors: Hiromi Ohtaki, Jun Nakamura, Hiroshi Izui, Tsuyoshi Nakamatsu
  • OtsA gene encoding trehalose-6-phosphate synthase from a coryneform bacterium
    Patent number: 7307160
    Abstract: L-Glutamic acid is produced by culturing a coryneform bacterium having L-glutamic acid producing ability, in which trehalose synthesis ability is decreased or deleted by, for example, disrupting the otsA gene derived from a coryneform bacterium source, coding for trehalose-6-phosphate synthase, to produce and accumulate L-glutamic acid in the medium, and collecting the L-glutamic acid from the medium.
    Type: Grant
    Filed: August 11, 2003
    Date of Patent: December 11, 2007
    Assignee: Ajinomoto Co. Inc.
    Inventors: Hiromi Ohtaki, Jun Nakamura, Hiroshi Izui, Tsuyoshi Nakamatsu
