An L-amino acid is produced by culturing a bacterium belonging to the family Enterobacteriaceae, which has an L-amino acid-producing ability and inherently has an activity of a glucose dehydrogenase that uses pyrroloquinoline quinone as a coenzyme, but has been modified so that the activity of the glucose dehydrogenase is reduced, in a medium to produce and accumulate the L-amino acid in culture, and collecting the L-amino acid from the culture. |
