FIELD: biotechnology, microbiology, amino acids.
SUBSTANCE: invention relates to a microorganism and a method for preparing L-amino acid. Method involve culturing a modified microorganism belonging to genus Escherichia wherein expression of leuO gene is attenuated followed by isolation of L-amino acid from cultural fluid. Invention provides enhancing effectiveness in preparing L-amino acid.
EFFECT: improved preparing method of L-amino acid.
