  • METHOD FOR PRODUCING AN L-AMINO ACID USING A BACTERIUM OF THE ENTEROBACTERIACEAE FAMILY
    Publication number: 20090203090
    Abstract: A method for producing an L-amino acid is described, for example L-threonine, L-lysine, L-histidine, L-phenylalanine, L-arginine, L-tryptophan, or L-glutamic acid, using a bacterium of the Enterobacteriaceae family, wherein the bacterium has been modified to enhance an activity of a wild-type alcohol dehydrogenase encoded by the adhE gene or a mutant alcohol dehydrogenase which is resistant to aerobic inactivation.
    Type: Application
