The invention relates to recombinant escherichia coli for producing 5-methylpyrazine-2-carboxylic acid, in particular to a method for increasing 5-methylpyrazine-2-carboxylic acid by adjusting the proportion of dimethylbenzene monooxygenase double subunits. According to the adjustment of the proportion of the dimethylbenzene monooxygenase double subunits, escherichia coli (E.coli BL21 (DE3) is used as an original strain, a 5-methylpyrazine-2-carboxylic acid synthetic route is constructed by utilizing CRISPR/cas9 homologous recombination to integrate xylene monooxygenase, benzyl alcohol dehydrogenase and benzaldehyde dehydrogenase genes. According to the strain disclosed by the invention, the yield of the 5-methylpyrazine-2-carboxylic acid in recombinant escherichia coli can be increased to15.6 g/L, and a foundation is laid for industrial production of the 5-methylpyrazine-2-carboxylic acid.
