    • The invention relates to a process for the production of L-amino acids, in which the following steps are carried out: a) fermentation of the coryneform bacteria producing the desired L-amino acid, in which bacteria at least one or more genes belonging to the group of the transcription regulators, selected from the group smtB, cgl1, hspR, cgl2, cebR, cgl3, gatR, glcR, tcmR, smtB2, dtxR, degA, galR, tipA2, malI, cgl4, arsR, merR, hrcA, glpR2, lexA, ccpA3 and degA2, has (have) been attenuated, especially excluded or expressed at a low level, 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 there are used bacteria in which further genes of the biosynthesis pathway of the desired L-amino acid are additionally enhanced, or there are used bacteria in which the metabolic pathways that reduce the formation of the desired L-amino acid are at least partially excluded.
    • 本发明涉及生产L-氨基酸的方法,其中进行以下步骤:a)产生所需L-氨基酸的棒状细菌的发酵,其中细菌中至少一种或多种属于 选自组smtB,cgl1,hspR,cgl2,cebR,cgl3,gatR,glcR,tcmR,smtB2,dtxR,degA,galR,tipA2,malI,cgl4,arsR,merR,hrcA,glpR2 ,lexA,ccpA3和degA2已被减毒,尤其是被排除或以低水平表达,b)期望的L-氨基酸在细菌培养基或细胞中的浓度,以及c)分离 L-氨基酸,并且任选地使用其中额外增强所需L-氨基酸的生物合成途径的其他基因的细菌,或使用细菌,其中减少所需L-氨基酸形成的代谢途径 酸至少部分被排除在外。
