Abstract:
L-glutamic acid is produced by culturing a microorganism in a liquid medium containing L-glutamic acid at a saturation concentration, wherein the microorganism can metabolize a carbon source at a specific pH, and also has an ability to accumulate L-glutamic acid in the medium in an amount which exceeds the saturation concentration of L-glutamic acid, wherein the pH of the medium is controlled so that L-glutamic acid precipitates.
