Figure 2From: Improving L-arabinose utilization of pentose fermenting Saccharomyces cerevisiaecells by heterologous expression of L-arabinose transporting sugar transportersGrowth properties of TSY01 cells expressing different sugar transporters ScGal2 (pHL125re), SsAraT (p426-opt-AraT-S) or AtStp2 (pTHStp2). Cells were spotted in serial dilutions on synthetic complete medium agar plates with various carbon sources: D-galactose, D-glucose, D-mannose and different L-arabinose concentrations (20 g/L and 5 g/L), and incubated at 30°C for 5 days (D-galactose, D-glucose, D-mannose) or 10 days (L-arabinose). Cells transformed with the empty vector p426H7-6HIS served as a negative control.Back to article page
