  • Process for the preparation of L-amino acids by overexpressing the tal gene encoding transaldolase
    Patent number: 7901913
    Abstract: The invention is directed to DNA sequences from coryneform bacteria, particularly Corynebacterium glutamicum, which encode a protein having transaldolase enzymatic activity. The invention also encompasses processes for the fermentative production of L-amino acids using bacteria in which a gene encoding transaldolase is amplified.

  • Process for the preparation of L-amino acids with amplification of the zwf gene
    Publication number: 20060014259
    Abstract: The invention relates to a process for the preparation of L-amino acids. The process involves fermenting an L-amino acid producing coryneform bacteria in a culture medium, concentrating L-amino acid in the culture medium or in the cells of the bacteria, and isolating the L-amino acid produced. The bacteria has an amplified gene encoding the Zwischenferment protein.

  • Process for the preparation of L-amino acids using a gene encoding 6-phosphogluconate dehydrogenase
    Publication number: 20030119154
    Abstract: The invention relates to a process for the preparation of L-amino acids. The process involves fermenting an L-amino acid producing coryneform bacteria in a culture medium, concentrating L-amino acid produced by the fermenting in the culture medium or in the cells of the bacteria, and isolating the L-amino acid produced. The bacteria has an overexpressed gene encoding 6-phosphogluconate dehydrogenase and a decreased or switched off gene encoding pyruvate oxidase. The L-amino acid may be L-lysine, L-threonine, L-isoleucine or L-tryptophan.
