    • 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的转录调节子组 ,lexA,ccpA3和degA2已经被减弱,特别是以低水平排除或表达,b)所需L-氨基酸在培养基中或细胞中的浓度,和c)分离 并且任选地使用细菌,其中期望的L-氨基酸的生物合成途径的其它基因被额外增强,或者使用其中代谢途径减少所需L-氨基酸形成的细菌 至少部分排除酸。
