Abstract
A method for producing L-glutamic acid which comprises culturing a microorganism belonging to the genus Klebsiella, Erwinia or Pantoea and having an ability to produce L-glutamic acid in a culture medium, and collecting produced L-glutamic acid from the culture medium. The microbial strain used is preferably a strain which decreases in or is deficient in an activity of an enzyme catalyzing a reaction branching from a pathway for L-glutamic acid biosynthesis and producing a compound other than L-glutamic acid, or a strain which increase in an activity of an enzyme catalyzing a reaction for L-glutamic acid biosynthesis.
