Effects of urea supplementation of 30 °Bx SCJ-VHG fermentations on glycerol and ethanol concentrations and gene expression in S. cerevisiae strains CAT-1 and W303-1A. Results for intracellular (int) and extracellular (ext) glycerol and ethanol concentrations and STL1 (glycerol active permease) and FPS1 (aquaglyceroporin) expression, by CAT-1 (light grey bars) and W303 (dark grey bars), are shown as ratios of the mean values obtained for SCJ urea-supplemented (SCJ-UR) to SCJ non-supplemented (SCJ) fermentations
