Abstract
L-Glutamic acid is produced by culturing a coryneform bacterium having L-glutamic acid producing ability, in which trehalose synthesis ability is decreased or deleted by, for example, disrupting the otsA gene derived from a coryneform bacterium source, coding for trehalose-6-phosphate synthase, to produce and accumulate L-glutamic acid in the medium, and collecting the L-glutamic acid from the medium.
