Enhancement of DHQ production by promoter adjustment. The original promoter of PGAL7 was replaced with different promoters, including the constitutive promoters of PSED1, PTDH3, PCCW12, and PHXT7 and inducible promoters of PGAL1, PGAL2, and PGAL10. Strains were co-expressed with the SmF3′H, ScCPR and CsF3Hs in the YPD medium supplemented with 1 g/L of NAR for DHQ production tests in the flasks. All experiments were performed in triplicates and error bars indicate SD
