Amino acid fermentation is conducted by fermenting bacterial cells in a culture medium in a fermentor and separating fermentation solution withdrawn from the fermentor into a solution containing said bacterial cells and a solution not containing bacterial cells by a cell separator. The solution containing said bacterial cells being circulated from said cell separator to said fermenter by circulating means to perform amino acid fermentation continuously, and bubbles being removed from said fermentation solution by a bubble separator before said fermentation solution is fed to said circulating means and said cell separator.

Process for the production of an amino acid using a fermentation

Amino acid fermentation is conducted by fermenting using bacterial cells in a culture medium in a fermentor and separating fermentation solution withdrawn from the fermentor into a solution containing the bacterial cells and a solution not containing bacterial cells by a cell separator, the solution containing the bacterial cells being circulated from the cell separator to the fermenter by a circulating device to perform amino acid fermentation continuously, and bubbles being removed from the fermentation solution by a bubble separator before the fermentation solution is fed to the circulating device and the cell separator.
