Abstract: The present disclosure relates to a microorganism for producing an L-amino acid with enhanced activity of α-glucosidase and a method for producing an L-amino acid using the same. According to the present disclosure, the microorganism of the genus Corynebacterium producing an L-amino acid has enhanced activity of α-glucosidase, thereby improving L-amino acid production yield. Therefore, the microorganism may be very usefully used for L-amino acid production.
