- Abstract
Patchoulol is a natural sesquiterpene alcohol with extensive applications in cosmetics and pharmaceuticals. In this study, we first constructed the synthesis pathway of patchoulol in Saccharomyces cerevisiae by expressing the patchoulol synthase PTS gene using the strong promoter GAL1. Afterward, the metabolic flux of the precursor was enhanced by strengthening the mevalonate pathway and balancing the precursor competition pathway, resulting in a 32.74-fold increase in patchoulol production. Subsequently, the supply of acetyl-CoA in yeast was increased by modifying transcriptional regulators and modulating the acetyl-CoA pathway, and the titer of patchoulol reached 155.94 mg/L. Finally, optimization of the fermentation conditions resulted in a titer of 195.96 mg/L in the shake flasks. Further, batch-fed fermentation in a 5 L bioreactor yielded 1.95 g/L. This work accelerated the development of a microbial cell factory for the production of patchoulol.
