Abstract
PURPOSE: To increase the concentration of glucose or sucrose in the culturing medium to more than 1.5 times the one obtainable by the conventional process, and to increase the amount of L-glutamic acid accumulated in the medium, by culturing L-glutamic acid-producing bacteria under specific conditions.
CONSTITUTION: L-glutamic acid-producing bacteria (e.g. Brevibacterium devaricatum, Corynebacterium acetoacidiphilum) are inoculated in a liquid medium containing glucose or sucrose as main carbon source, and aerobically cultured. When the concentraion of the sucrose is decreased to a predetermined value below 10 g/1, glucose or sucrose is added to the medium, and at the same time, aqueous ammonic (or ammonia gas) or an alkali hydroxide is added to the medium to keep the ammonium ion concentration in the medium between 0.3 and 10 g/d1. The aqueous ammonia raises the concentration, while the alkali hydroxide lowers.
