This application discloses methods for the preparation of L-amino acids, which comprises fermentation of a desired L-amino acid-producing bacteria in which at least the tal gene is amplified. In some embodiments, genes of the biosynthesis pathway of the desired L-amino acid are additionally amplified.

Process for the preparation of L-amino acids

The invention is directed to DNA sequences from coryneform bacteria, particularly, 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 by overexpressing the tal gene encoding transaldolase

The invention is directed to DNA sequences from coryneform bacteria which encode a protein having transaldolase enzymatic activity. The invention also encompasses methods for the fermentative production of L-amino acids using bacteria in which the gene encoding transaldolase is amplified.
