Abstract

PURPOSE: To improve the yield of L-glutamic acid by the fermentation method, by adding ethanol to a culture medium to give a specific ethanolic concentration in the culture medium in the first half and the second half stages of the cultivation.
CONSTITUTION: L-Glutamic acid is produced from ethanol as a raw material by using bacteria, belonging to the genus Corynebacterium, etc., and capable of producing the L-glutamic acid by the fermentation method. In the process, any point between a time when the number of the bacteria to be used reaches 80% of that at the completion of the logarithmic growth phase and the end point of the logarithmic growth phase is taken as a boundary, and the cultivation is carried out while adding ethanol to a culture medium to give the ethanolic concentration in the first half stage in the cultivation of 0.05W1.5 g/dl and the ethanolic concentration in the second half stage in the cultivation of 2.5W5.0 g/dl. After the completion of the cultivation, the L-glutamic acid is recovered from the culture fluid.
