GA-production by engineered Y. lipolytica strains. A. Overview of GA-producing strains showing which GA-biosynthetic genes were expressed. B. GA4-production for ST8417, ST8602, and ST8580. C. GA7-production for ST8417, ST8602, and ST8580. D. GA3-production for ST8417, ST8602, and ST8580. TR, trace amounts. Three biological replicates were used to calculate titer averages and standard deviations for all strains.
