<p>L-lysine is efficiently produced by incubating a microorganism belonging to the genus Escherichia in which the activity of lysine decarboxylase participating in the decomposition of L-lysine has been declined or deleted, for example, a bacterium of the genus Escherichia in which the expression of a novel gene coding for lysine decarboxylase and/or a known gene cadA has been suppressed, and harvesting the L-lysine thus formed and accumulated in the culture medium.</p> |
