摘要
The invention provides a process for the production of L-amino acids, in particular L-threonine, in which the following steps are performed: a) fermentation of microorganisms from the Enterobacteriaceae family, in which the galP gene or nucleotide sequences coding for the galp gene product are overexpressed and which produce the desired L-amino acid; b) enrichment of the desired L-amino acid in the medium or in cells of the bacteria; and c) isolation of the desired L-amino acid.
