Figure 2. Production of squalene, lanosterol, ergosterol, β-amyrin and oleanolic acid by engineered S. cerevisiae strains BY4742-TRP, BY-T1, BY-βA-G and BY-OA.

Figure 2

All strains were cultivated in YPD medium with 2% glucose for 7 days. Three replicates were performed, and the error bars represented standard deviation. All these five chemicals were measured in the four strains. β-amyrin and oleanolic acid were not detected in strains BY4742-TRP and BY-T1. Oleanolic acid was not detected in strain BY-βA-G.
