  • Bacterium having enhanced 2-oxoglutarate dehydrogenase activity
    Patent number: 7993888
    Abstract: Provided is a bacterium which is capable of producing an organic acid and is modified so as to have an enhanced 2-oxoglutarate dehydrogenase activity as compared with that of an unmodified strain. An organic acid such as succinic acid can be produced by culturing the bacterium.

  • Method for producing L-amino acid
    Patent number: 7833762
    Abstract: An L-amino acid is produced by culturing an L-amino acid-producing bacterium which belongs to the Enterobacteriaceae family and which has been modified so that the acetyl-CoA synthetase activity is increased.
    Type: Grant
    Filed: September 30, 2008
    Date of Patent: November 16, 2010
    Assignee: Ajinomoto Co., Inc.
    Inventors: Saori Kataoka, Takuji Ueda, Yuji Joe, Chie Koseki
  • Process for production of succinic acid
    Patent number: 7829316
    Abstract: Disclosed is a process for production of succinic acid, which comprises the step of reacting a bacterium which has been modified so as to increase the expression of a sucE1 gene or a product produced by any treatment of the bacterium with an organic raw material in a reaction solution containing a carbonate ion, a bicarbonate ion or carbon dioxide gas to thereby yield the desired succinic acid.
