Focus on the bioconversion of isoamyl alcohol to isoamyl acetate. a Changes in total isoamyl acetate production as a function of total isoamyl alcohol production in SM330 with 8 mg/L of phytosterols for Lalvin EC1118® (blue) and Affinity™ ECA5 (red). The arrows indicate the timing of sampling for transcriptomic analyses. b Changes in total isoamyl acetate production as a function of total isoamyl alcohol production subsequently to phytosterol additions for Lalvin EC1118® (blue) and Affinity™ ECA5 (purple and red). For Lalvin EC1118®, despite phytosterol additions, bioconversion yield between the two compounds remains identical: 0.0241 (R2 = 0.947). For Affinity™ ECA5, four linear phases are identified; their yields of conversion are 0.0689 (R2 = 0.990); 0.0367 (R2 = 0.966); 0.0696 (R2 = 0.991); and 0.0351 (R2 = 0.955)
