METHOD OF PRODUCING L-AMINO ACIDS Russian patent published in 2017 - IPC C12N15/77 C12N15/52 C12P13/08

Abstract RU 2614258 C2

FIELD: biotechnology.

SUBSTANCE: invention relates to biotechnology. Method of producing L-lysine using recombinant coryneform microorganism able to produce L-lysine is disclosed, where recombinant coryneform microorganism is transformed by means of insertion of acetate-inducible promoter below stop codon of target gene on chromosome for attenuation of target gene expression and enhancing of ability of recombinant coryneform microorganism to produce L-lysine, where target gene is gene located in nodal point of L-lysine biosynthesis path.

EFFECT: invention increases production of L-lysine in comparison with parent strain of microorganism.
