Abstract
Provided is an efficient process for producing L-glutamine or L-glutamic acid using a microorganism. L-glutamine or L-glutamic acid is produced by culturing in a medium a microorganism in which has an ability to produce L-glutamine or L-glutamic acid, and in which an ability to form a superhelical double-stranded DNA is decreased compared with that of the parent strain, producing and accumulating L-glutamine or L-glutamic acid in the medium, and recovering L-glutamine or L-glutamic acid from the medium.
