FIELD: biotechnologies.
SUBSTANCE: invention represents a method for obtaining L-aminoacid chosen from the group consisting of L-glutamine, L-glutamine acid, L-proline, L-arginine, L-citrulline and L-ornithine. The method involves growth of bacterium of Enterobacteriaceae family, which is modified so that expression of yeel gene in the above bacterium is strengthened, and extraction of the above L-aminoacid from cultural liquid.
EFFECT: invention allows obtaining L-aminoacids with high efficiency degree.
