| 摘要 |
<p>This invention relates to a method for the fermentative preparation of L-amino acids, especially L-methionine in which one ferments recombinant microorganisms producing the wanted L-amino acid, preferably ferments coryneform bacteria, which take up less or no methionine from the surrounding medium, in which one attenuates coding of one or a plurality of the genes selected from the yaeC, abc and yaeE group for the metD2 methionine uptake system, especially deactivates, or expresses at a lower level, and these recombinant microorganisms.</p> |
