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