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 present invention relates to polynucleotides that encode proteins having OpcA enzymatic activity. These polynucleotides can be used for increasing lysine biosynthesis in
