Estimating the term…
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.
A method for producing L-glutamic acid which comprises culturing a microorganism in a liquid culture medium to produce and accumulate L-glutamic acid extracellularly in the culture medium, and collecting the L-glutamic acid from the culture medium, wherein the microorganism belongs to the genus Klebsiella, the genus Erwinia or the genus Pantoea, and has been modified so that the microorganism has an increased activity of an enzyme catalyzing a reaction for L-glutamic acid biosynthesis.
