Patent ID: 8129151

Claim:
A method for producing L-glutamic acid, comprising: culturing a microorganism in a liquid culture medium for a time and under conditions suitable for the production and accumulation of L-glutamic acid in the culture medium wherein production of L-glutamic acid by said microorganism is increased relative to that in the corresponding wild-type microorganism, and collecting the L-glutamic acid from the culture medium; wherein said microorganism belongs to the genus Pantoea or Serratia and has (1) an ability to produce L-glutamic acid in a culture medium, and (2) at least one of the following properties: (a) the microorganism has an increased activity of at least one enzyme selected from the group consisting of citrate synthase, phosphoenolpyruvate carboxylase, and glutamate dehydrogenase; and (b) the microorganism has decreased activity of α-ketoglutarate dehydrogenase.
