Abstract
The invention relates to a process for the preparation of L-amino acids by the fermentation of recombinant microorganisms of the family Enterobacteriaceae. The microorganisms produce the desired L-amino acid and overexpress theoryibD gene encoding the putative glycosyl transferase enzyme. The microorganisms are cultivated in a medium under conditions in which the desired L-amino acid is enriched in the medium or in the cells. The amino acid is then isolated, optionally with constituents of the fermentation broth, and/or all or part (≧0 to 100%) of the biomass.
