Fig. 9From: Metabolic engineering of the oleaginous yeast Yarrowia lipolytica PO1f for production of erythritol from glycerolProduction of erythritol by Y. lipolytica strains during growth on crude glycerol (100Â g/L) in PSM medium. PO1f (A), and PO1f-PYP-GK-TKL (B). 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-axisBack to article page
