Abstract
A method is described for producing an L-amino acid, for example L-threonine, L-lysine, L-leucine, L-histidine, L-cysteine, L-phenylalanine, L-arginine, L-tryptophan, L-glutamic acid, L-valine, and L-isoleucine, by fermentation of glucose using a bacterium of the Enterobacteriaceae family, wherein the bacterium has been modified to enhance the activity of the high-affinity arabinose transporter coded by the araFGH operon.
