A METHOD FOR PRODUCING AN L-AMINO ACID USING A BACTERIUM OF THE ENTEROBACTERIACEAE FAMILY WITH ENHANCED EXPRESSION OF THE ALSABC OPERON

摘要

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, L-proline, 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 allose transporter coded by the alsABC operon.
