摘要： A method is provided for producing an L-amino acid which includes the steps of culturing a bacterium, which belongs to the family Enterobacteriaceae and is able to produce an L-amino acid, in a medium containing glycerol as a carbon source to produce and accumulate an L-amino acid in the medium, and collecting the L-amino acid from the culture. The culture is performed as a fed-batch culture or a continuous culture, and a feed medium containing glycerol is added to the fermentation medium so that the glycerol concentration in the fermentation medium is 5 g/L or higher.
