FIELD: biotechnology, microbiology, amino acids.
SUBSTANCE: method involves culturing bacterium of genus Escherichia modified by such manner that activity of enzyme transaldolase in cell of such bacterium is increased. Prepared and accumulated L-histidine is isolated from cultural fluid. The claimed invention provides preparing L-histidine with the enhanced degree of effectiveness.
EFFECT: enhanced yield of L-histidine.
