Glutamic Acid; Glutamine Patents (Class 435/110)
  • Patent number: 8354254
    Abstract: An L-amino acid is produced by culturing a bacterium having an L-amino acid-producing ability in a medium containing a processed product of a microalga which promotes production and accumulation of the L-amino acid by the bacterium. The process product is produced by disrupting the culture of the microalga, and/or extracting the culture of the microalga, or fractionating the culture of the microalga or the disrupted culture. The processed product contains a mixture of organic substances produced by the microalga, a hydrolysate of the disrupted microalga culture, and/or an extract or fractionation product of the microalga culture. The processed product can also contain a saccarification product of starch or a hydrolysate of fats and oils. The bacterium is cultured to produce and accumulate the L-amino acid in culture, and the L-amino acid is collected from the culture.

  • Publication number: 20110124059
    Abstract: According to the present invention, it is possible to provide a microorganism belonging to the genus Corynebacterium, wherein the activity of (1) a protein having the amino acid sequence shown by any one of SEQ ID NO:1 to 3, or (2) a protein having a homology of 80% or more to the amino acid sequence shown by any one of SEQ ID NO:1 to 3, and having substantially the same activity as the activity of a protein having the amino acid sequence shown by any one of SEQ ID NO:1 to 3, has been reduced or lost, and wherein the activity of (3) a protein having the amino acid sequence shown by SEQ ID NO:4, or (4) a protein having a homology of 80% or more to the amino acid sequence shown by SEQ ID NO:4, and having substantially the same activity as the activity of a protein having the amino acid sequence shown by SEQ ID NO:4, has been reduced or lost, and a process for producing L-glutamine using the microorganism and the like.

  • Patent number: 7943364
    Abstract: L-glutamine is produced by culturing a coryneform bacterium having L-glutamine-producing ability and modified so that intracellular glutaminase activity is reduced, and preferably also modified so that intracellular glutamine synthetase activity is enhanced. The method of production includes culturing the bacterium in a medium, followed by accumulation of L-glutamine in the medium and collecting the L-glutamine from the medium.

  • Patent number: 7927844
    Abstract: A coryneform bacterium that is modified by using a yggB gene so that L-glutamic acid-producing ability is enhanced as compared to a non-modified strains is cultured in a medium to cause accumulation of L-glutamic acid in the medium or bacterial cells, and L-glutamic acid is collected from the medium or cells.

  • Publication number: 20110053227
    Abstract: The invention relates to a process for preparing L-amino acids by fermenting recombinant microorganisms of the Enterobacteriaceae family, characterized in that a) the desired L-amino acid-producing microorganisms, in which the yjcG-ORF, or nucleotide sequences or alleles encoding the gene product, is/are enhanced, in particular overexpressed, is cultured in a medium under conditions under which the desired L-amino acid is accumulated in the medium or in the cells, and b) the desired L-amino acid is isolated, with, where appropriate, constituents of the fermentation broth, and/or the biomass remaining in its/their entirety or in portions (from ?0 to 100%) in the isolated product or being removed completely.

  • Patent number: RE42350
    Abstract: A microorganism is provided which can metabolize a carbon source at a specific pH in a liquid medium containing L-glutamic acid at a saturation concentration and the carbon source, and which has ability to accumulate L-glutamic acid in an amount exceeding the amount corresponding to the saturation concentration in the liquid medium at the pH. Also provided is a method for producing L-glutamic acid by fermentation, which comprises culturing the microorganism in a liquid medium of which pH is adjusted to a pH at which L-glutamic acid is precipitated, to produce and accumulate L-glutamic acid and precipitate L-glutamic acid in the medium.
