摘要：
A method for producing an L-amino acid, such as L-histidine, L-threonine, L-lysine, L-glutamic acid, and L-tryptophan, using bacterium belonging to the genus Escherichia which has increased expression of genes, such as those of the xylABFGHR locus, which encode the xylose utilization enzymes, is disclosed. The method includes cultivating the L-amino acid producing bacterium in a culture medium containing xylose, and collecting the L-amino acid from the culture medium.
