ABSTRACT:
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 fruR 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.
