- Abstract: Limonene and its derivative perillic acid are widely used in food, cosmetics, health products, medicine and other industries as important bioactive natural products. However, inefficient plant extraction and high energy-consuming chemical synthesis hamper the industrial production of limonene and perillic acid. In this study, limonene synthase from Mentha spicata was expressed in Saccharomyces cerevisiae by peroxisome compartmentalization, and the yield of limonene was 0.038 mg/L. The genes involved in limonene synthesis, ERG10, ERG13, tHMGR, ERG12, ERG8, IDI1, MVD1, ERG20ww and tLS, were step-wise expressed via modular engineering to study their effects on limonene yield. The yield of limonene increased to 1.14 mg/L by increasing the precursor module. Using the plasmid with high copy number to express the above key genes, the yield of limonene significantly increased up to 86.74 mg/L, which was 4 337 times higher than that of the original strain. Using the limonene-producing strain as the starting strain, the production of perillic acid was successfully achieved by expressing cytochrome P450 enzyme gene from Salvia miltiorrhiza, and the yield reached 4.42 mg/L. The results may facilitate the construction of cell factory with high yield of monoterpene products by S. cerevisiae.
