Growth profile and production of erythritol with additional metabolites for Y. lipolytica strains during fed-batch cultures on glycerol in PSM medium. PO1f (A), and PO1f-PYP-GK-TKL (B). Glycerol at 100 g/L was added in shake flasks after 4 days and 8 days reaching the total concentration of 300 g/L. Squares and circles were used to denote glycerol and OD, respectively, and plotted on left Y-axis. Triangles, inverted triangles, diamonds, and hexagons were used to denote mannitol, arabitol, erythritol, and citric acid, respectively, and plotted on right Y-axis
