Abstract
The present invention relates to a recombinant strain for producing shikimic acid, in which a target gene that regulates the asymmetric cell division and target genes that regulate the shikimic acid production are expressed The target gene that regulates the asymmetric cell division includes cytoskeletal protein PopZ coding gene popZ, and the target genes that regulate the shikimic acid production include DAHP synthase coding gene aroG, 3-dehydroquinate synthase coding gene aroB, and transketolase coding gene tktA. The recombinant strain of the present invention realizes the de novo synthesis of shikimic acid using glucose as a substrate, with a low cost. After fermentation with the strain in a 7.5 L fermentor, the highest production of shikimic acid is 88.1 g/L, the yield is 0.33 g/g, and the production intensity of shikimic acid is 1.1 g/L/h.
