"BACTERIA BELONGING TO THE GENDER ESCHERICHIA, AND, METHOD FOR THE PRODUCTION OF L-THREONIN OR L-ISOLEUCINE". Threonine or isoleucine is to be produced by cultivating a bacterium belonging to the genus Escherichia, which has an ability to produce L-threonine or L-isoleucine, and in which the intracellular phosphoenolpyruvate carboxylase activity and the transhydrogenase activity are intensified, in a medium for produce and accumulate threonine or isolcucine in the medium, and collect threonine or isoleucine from the medium. |
