Patent AT-E399875-T1: [Translated] METHOD FOR THE FERMENTATIVE PRODUCTION OF L-AMINO ACIDS BY ENTEROBACTERIACEAE STRAINS WITH ENHANCED EXPRESSION OF THE RSEB GENE

The invention relates to a process for the fermentative preparation of L-amino acids, in particular L-threonine, in which the following steps are carried out: a) fermentation of the microorganisms of the Enterobacteriaceae family which produce the desired L-amino acid and in which the rseB gene or nucleotide sequences which code for it are enhanced, in particular over-expressed, b) concentration of the desired L-amino acid in the medium or in the cells of the bacteria, and c) isolation of the desired L-amino acid <IMAGE>
