ABSTRACT:
A coryneform bacterium which has enhanced intracellular pyruvate carboxylase activity obtained by increasing copy number of a gene encoding the intracellular pyruvate carboxylase, or by enhancing function of a expression regulatory sequence for the gene, and has L-glutamic acid-producing ability is cultured in a medium so that L-glutamic acid should be produced and accumulated in the culture, and L-glutamic acid is collected from the culture.
