Abstract

FIELD: biotechnology, biochemistry, microbiology. SUBSTANCE: method involves culturing the strain of bacterium Bacillus subtilis with reduced activity of shikimate kinase or with deficiency of activity of 5-enol-pyruvoylshikimate-3-phosphate synthase but the indicated bacterium is able to produce shikimic acid. Shikimic acid is accumulated in medium and it is isolated from medium. The strain of bacterium Bacillus subtilis ID3 (VKPM B-7755) is a producer of shikimic acid. Recombinant strain is obtained by transformation of this strain with plasmid comprising gene encoding (3-deoxy-D-arabinoheptulosonic acid)-7-phosphate synthase or by reduction of activity of 5-enol-pyruvoylshikimate-3-phosphate synthase as result of mutation in gene aroE. EFFECT: enhanced production of shikimic acid. 12 cl, 11 dwg, 9 tbl _
