Patent abstract
A method for producing L-glutamic acid by fermentation, which comprises culturing a microorganism having L-glutamic acid-producing ability in a liquid medium of which pH is adjusted to a condition under which L-glutamic acid produced by the microorganism is allowed to be precipitated, to allow L-glutamic acid to be produced and accumulated with precipitation of L-glutamic acid accompanied, wherein an operation causing existence of L-glutamic acid crystals in the medium is performed when a concentration of L-glutamic acid in the medium is lower than the concentration at which spontaneous crystallization occurs.
