METHOD FOR PRODUCING L-LYSINE Russian patent published in 2005 - IPC

Abstract RU 2264461 C2

FIELD: biotechnology, amino acids, microbiology.

SUBSTANCE: invention relates to a method for preparing L-lysine by fermentation of corynebacteria with separated or combined enhanced nucleotide sequences of genes encoding biosynthesis of L-lysine. Corynebacteria carry mutations MC20 or MA16 in promoter of gene dapA and the enhanced gene lysE. Invention provides producing L-lysine with the enhanced effectiveness degree.

EFFECT: improved producing method.
