Abstract
The invention relates to a method for the production of L-amino acids by fermentation of recombinant microorganisms of the Enterobacteriaceae family, characterized in that a) the microorganisms producing the desired L-amino acid and wherein the lamB-gene or nucleotide sequence coding for the gene product maltoporin is amplified, particularly overexpressed, are cultivated in a medium in conditions enabling the desired L-amino acid to be enriched in the medium or in cells, and b) the desired L-amino acid is isolated, wherein constituents of the fermentation broth and/or biomass remain in the entirety thereof or in parts thereof (=0 bis 100%) in the isolated product or are fully removed.
