  • Process for producing L-glutamic acid by fermentation
    Patent number: 4529697
    Abstract: A process for producing L-glutamic acid by fermentation is disclosed, which process comprises culturing aerobically in a culture medium a mutant of the genus Brevibacterium or Corynebacterium which has an increased superoxide dismutase activity and is capable of producing L-glutamic acid in the culture medium and recovering the L-glutamic acid. The yield of L-glutamic acid can be increased by using the aforementioned mutants.
    Type: Grant
    Filed: March 15, 1983
    Date of Patent: July 16, 1985
    Assignee: Ajinomoto Co., Inc.

  • Method for producing L-glutamic acid by fermentation
    Patent number: 4389483
    Abstract: A method for producing L-glutamic acid by fermentation which comprises culturing aerobically in a culture medium a mutant of the genus of Brevibacterium or Corynebaterium which is resistant to Decoyinine or Tubercidin and capable of producing L-glutamic acid, and recovering the L-glutamic acid accumulated in the culture medium.
    Type: Grant
    Filed: December 17, 1981
    Date of Patent: June 21, 1983
    Assignee: Ajinomoto Company Incorporated
    Inventors: Hirofumi Hiraga, Minoru Yoshimura, Shigeho Ikeda, Hiroe Yoshii
  • Method for producing L-glutamic acid by fermentation
    Patent number: 4368266
    Abstract: Mutants of the genus Brevibacterium or Corynebacterium requiring acetic acid for growth produce L-glutamic acid in an improved yield, especially when they are cultured in an aqueous culture medium containing both saccharide and aliphatic alcohol or acid as the carbon source.
    Type: Grant
    Filed: December 19, 1980
    Date of Patent: January 11, 1983
    Assignee: Ajinomoto Company Incorporated
    Inventors: Osamu Tosaka, Yutaka Murakami, Shigeho Ikeda, Hiroe Yoshii
  • Method for producing L-glutamic acid by fermentation
    Patent number: 4347317
    Abstract: Mutants of the genus Brevibacterium or Coryne-bacterium resistant to a respiratory inhibitor or ADP phosphorylation inhibitor produced L-glutamic acid in a high yield, when they are cultured aerobically in an aqueous culture medium.
