Abstract (en)
[origin: WO03054206A1] The invention relates to a process for the preparation of L-amino acids, in which the following steps are carried out: a) fermentation of the coryneform bacteria which produce the desired L-amino acid and in which at least the gene which codes for the C4-dicarboxylate transport protein is attenuated, b) concentration of the desired L-amino acid in the medium or in the cells of the bacteria, and c) isolation of the L-amino acid, and optionally bacteria in which further genes of the biosynthesis pathway of the desired L-amino acid are additionally enhanced are employed, or bacteria in which the metabolic pathways which reduce the formation of the desired L-amino acid are at least partly eliminated are employed.
