  • Method for producing an L-amino acid in an bacterium via altering expression levels of target proteins
    Patent number: 7399617
    Abstract: A bacterium belonging to the genus Escherichia which has an ability to produce an L-amino acid, wherein the ability to produce the L-amino acid is increased by increasing expression of an L-amino acid excretion protein is described. A method for producing the L-amino acid using the bacterium is also described.
    Type: Grant
    Filed: March 3, 2006
    Date of Patent: July 15, 2008

  • Eschericha bacteria overexpressing the yahn gene for feedback-insensitive amino acid production
    Patent number: 6979560
    Abstract: A bacterium belonging to the genus Escherichia and having an ability to produce an L-amino acid, wherein the ability to produce the L-amino acid is increased by increasing an expression amount of an L-amino acid excretion protein, and a method for producing the L-amino acid using the bacterium.
    Type: Grant
    Filed: December 13, 1999
    Date of Patent: December 27, 2005
    Assignee: Ajinomoto Co., Inc.
    Inventors: Vitaliy Arkadievich Livshits, Natalia Pavlovna Zakataeva, Kazuo Nakanishi, Vladimir Veniaminovich Aleshin, Petr Vladimirovich Troshin, Irina Lyvovna Tokhmakova
  • Method for producing uridine-5'-monophosphate by fermentation using mutant strains of coryneform bacteria
    Patent number: 6344344
    Abstract: Uridine-5′-monophosphate is produced by cultivating in a nutrient medium an uridine-5′-monophosphate producing mutant of coryneform bacterium and which is characterized by at least a resistance to growth inhibition by pyrimidine analogue or a deficiency in uridine degrading activity or combination of said property by protoplast fusion. This method has the advantage of decreased production of uracil. Thus, uridine-5′-monophosphate can be produced in much greater yields, compared with known methods.
