FIELD: biotechnology, microbiology, amino acids.
SUBSTANCE: invention represents a method for preparing L-threonine. Method involves culturing a microorganism belonging to Escherichia genus wherein dinJ-yafQ operon is inactivated in nutrient medium and isolation of accumulated L-threonine. Invention provides preparing L-threonine with high degree of effectiveness.
EFFECT: improved preparing method of L-threonine.
