| 摘要 |
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 at least the mqo gene 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 are used in which further genes of the biosynthesis pathway of the desired L-amino acid are additionally enhanced, or bacteria are used in which at least some of the metabolic pathways reducing formation of the desired L-amino acid are excluded. |
