| description | PROBLEM TO BE SOLVED: To improve the L-threonine or L-isoleucine productive ability of a bacterium belonging to the genus Escherichia. SOLUTION: Threonine or isoleucine is produced by culturing the bacterium belonging to the genus Escherichia which features having L-threonine or L- isoleucine productive ability and showing increased intracellular phosphoenol pyruvic acid carboxylase activity and transhydrogenase activity in a culture medium to make the bacterium form and accumulate threonine or isoleucine in the culture medium and by collecting threonine or isoleucine from the culture medium. |
