bacterium belonging to the genus escherichia and having an ability to produce an l-amino acid selected from the group consisting of l-lysine, l-glutamic acid, l-alanine, l-valine, l-histidine, l-proline and l-isoleucine, and, the process for producing an 1-amino acid selected from the group consisting of 1-lysine, 1-glutamic acid, 1-alanine, 1-valine, 1-histidine, 1-proline and 1-isoleucine.

摘要

A bacterium belonging to the genus Escherichia and having an ability to produce an L-amino acid, wherein the ability to produce the L-amino acid is increased by increasing an expression amount of an L-amino acid excretion protein, and a method for producing the L-amino acid using the bacterium.
