METHOD FOR PRODUCING L-HISTIDINE USING A BACTERIUM BELONGING TO THE GENUS Escherichia, WHEREIN THE sanA GENE IS INACTIVATED Russian patent published in 2008 - IPC C12N1/21 C12P13/04 C12R1/19

Abstract RU 2326164 C2

FIELD: biotechnologies.

SUBSTANCE: the invention relates to biotechnology and represents a method for producing L-histidine using a bacterium of the genus Escherichia, which is modified so that in said bacterium the sanA gene is inactivated by means of dividing the sanA gene in the bacterium chromosome.

EFFECT: producing L-histidine with a high level of efficiency.
