FIELD: biotechnology, microbiology, biochemistry, molecular biology.
SUBSTANCE: for preparing l-lysine method involves carrying out fermentation with using corynebacterium strain producing L-lysine wherein polynucleotide comprising the polynucleotide sequence encoding the component H of phosphotransferase system is enhanced. Prepared L-lysine is isolated. The claimed invention provides enhancing the effectiveness of synthesis of L-lysine by corynebacteria.
EFFECT: valuable properties of strain, enhanced effectiveness of amino acid synthesis.
