Engineering the downstream mevalonate pathway to improve the β-farnesene production. A Metabolic pathway from mevalonate to β-farnesene. B The β-farnesene production of the strains containing different fusion forms of ERG20 and AanFSK197T/F180H. C Overexpression of the genes encoding the enzymes in the mevalonate to β-farnesene pathway improved the β-farnesene production. mFS represents AanFSK197T/F180H. Data represent the mean ± SD of three biological replicates. Statistical analysis was performed by using one-way ANOVA (**p < 0.05, ***p < 0.01)
