FIELD: biotechnology, microbiology, amino acids.
SUBSTANCE: invention relates to a microorganism and a method for preparing amino acid. Method involves preparing a microorganism as a producer of L-threonine belonging to genus Escherichia by inactivation of dicB gene. Microorganisms are grown in nutrient medium and L-threonine is isolated from cultural fluid. Invention provides enhancing effectiveness of method for preparing L-threonine.
EFFECT: improved preparing method of amino acid.
