PROCESS FOR THE PREPARATION OF L-AMINO ACIDS WITH AMPLIFICATION OF THE ZWF GENE

摘要

The invention relates to a process for the preparation of L-amino acids by fermentation of coryneform bacteria, which comprises carrying out the following steps: a) fermenting the L-amino acid-producing bacteria in which at least the zwf gene is amplified, b) concentrating the L-amino acid in the medium or in the cells of the bacteria and c) isolating the L-amino acid produced.
