  • Method for Producing an L-Amino Acid
    Publication number: 20080050784
    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: Application

  • Novel gene and method for producing L-amino acids
    Publication number: 20050239177
    Abstract: The present invention describes a bacterium which has an ability to produce an amino acid and in which the rhtC gene encoding a protein having an enhanced activity of imparting L-threonine resistance to a bacterium expressing the protein. Preferably, the bacterium further includes an rhtB gene encoding for a protein having an enhanced activity of imparting to a bacterium L-homoserine resistance expressing the protein. The present invention also describes a method of cultivating the bacterium in a culture medium to produce and accumulate amino acids in the medium, and the amino acid is recovered from the medium.
