FIELD: biotechnologies.
SUBSTANCE: invention represents bacterium of Escherichia family, which produces L-aminoacid chosen from the group consisting of L-glutamine, L-glutamine acid, L-proline, L-arginine, L-citrulline and L-ornithine. With that, bacterium is modified so that expression of bssR gene in the above bacterium is strengthened. The invention also refers to the 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 using the above bacterium.
EFFECT: invention allows obtaining aminoacids with high efficiency degree.
