摘要：
A mutant of the genus Escherichia is described, the .alpha.-ketoglutarate dehydrogenase activity of which is deficient or reduced, and/or the phosphoenol pyruvate carboxylase and/or glutamate dehydrogenase activities of which are amplified. The mutant is useful in the fermentative production of L-glutamic acid.
