PROCESS FOR PRODUCING L-LYSINE

摘要

A coryneform bacterium having a high L-lysine productivity is provided by integrating a gene coding for a coryneform-origin aspartokinase released of feedback inhibition caused by L-lysine and L-threonine into a DNA of a chromosome of a coryneform bacterium carrying attenuated homoserine dehydrogenase or a coryneform bacterium deficient in a homoserine dehydrogenase gene.
