Patent AT-E401413-T1: [Translated] METHOD FOR PRODUCING L-AMINO ACIDS USING STRAINS FROM THE ENTEROBACTERIACEAE FAMILY WHICH CONTAIN AN ATTENUATE ACEAGEN

The invention relates to a process for the production of L-amino acids, in particular L-threonine, in which the following steps are carried out: a) fermentation of the microorganisms of the family Enterobacteriaceae producing the desired L-amino acid, in which the aceA gene or nucleotide sequences coding therefor are attenuated, in particular are switched off; b) enrichment of the L-amino acid in the medium or in the cells of the bacteria; and c) isolation of the L-amino acid.
