FIELD: biotechnology, microbiology, amino acids.
SUBSTANCE: invention represents a method for preparing L-threonine or L-arginine. Method involves culturing a modified microorganism belonging to Escherichia genus wherein ybiV gene is inactivated and isolation of L-threonine or L-arginine from cultural fluid. Invention provides preparing L-threonine or L-arginine with the high degree of effectiveness.
EFFECT: improved preparing method of amino acids.
