Abstract
Sclareolide, a natural product with bioactive and fragrant properties, is not only utilized in the food, healthcare, and cosmetics industries but also serves as a precursor for the production of ambroxide and some bioactive compounds. Currently, there are three primary methods for producing sclareolide: direct extraction from plants, chemical synthesis using sclareol as a precursor, and the biotransformation of sclareol. Here, we established a platform for producing sclareolide through a modular coculture system with Saccharomyces cerevisiae and Cryptococcus albidus ATCC 20918. S. cerevisiae was engineered for de novo sclareol biosynthesis from glucose, while C. albidus enabled the production of sclareolide via sclareol biotransformation. To enhance the supply of sclareol, a recombinant yeast strain was constructed through metabolic engineering to produce 536.2 mg/L of sclareol. Further improvement of the coculture system for sclareolide production was achieved by incorporating Triton X-100 facilitated intermediate permeability, inoculation proportion adjustment, and culture temperature optimization. These refinements culminated in a sclareolide yield of 626.3 mg/L. This study presents a novel streamlined and efficient approach for sclareolide preparation, showcasing the potential of the microbial consortium in sustainable bioproduction.
