FIELD: biotechnology, microbiology, amino acids.
SUBSTANCE: invention proposes a method for preparing such L-amino acids as L-threonine or L-lysine using a microorganism belonging to Escherichia genus that is modified and nac gene is inactivated in this microorganism. Invention provides preparing L-threonine or L-lysine with high degree of effectiveness.
EFFECT: improved preparing method.
