Fig. 5From: Improving furfural tolerance in a xylose-fermenting yeast Spathaspora passalidarum CMUWF1–2 via adaptive laboratory evolutionComparison of stress tolerances (a) and glucose repression (b) between S. passalidarum CMUWF1−2 and AF2.5. The strains were spotted on YPD agar under different stresses and YP with various sugars supplemented with 2–DOG to observe stress tolerances and glucose repression, respectively. The cell suspension, containing approximately l × 107 cells/ml was 10-fold serially diluted and spotted onto agar plates, which were incubated for 72 h. Data were reproduced by two independent experiments. Arrows indicate the presence of spotted cellsBack to article page
