Key points

  • The maximum yield of EPS produced by mutant CM-pgm-H was 4.63 ± 0.23 g/L, whereas the yield of wild-type strain was 3.43 ± 0.26 g/L. In addition, the data obtained in the present study indicated that the yield of EPS produced by the engineered strain treated with the co-overexpression of phosphoglucomutase and UDP-glucose 6-dehydrogenase genes achieved 6.11 ± 0.21 g/L, which was increased by 78.13% compared with that by the wild-type strain
  • CM-pgm-H obtained the highest EPS content than that of gk, ugp, and ugdh mutants
  • This result indicated that the content of protein phosphoglucomutase was an important influencing factor on the CP production of C. militaris
  • Furthermore, the EPS production of CM-ugdh-pgm-M was significantly improved by 1.78-fold by co-overexpression
  • Therefore, our engineering strategies will play an important role in the development of C. militaris for the sustainable production of Cordyceps polysaccharides
