Growth kinetics of a control strain without XI and strains containing plasmid vector expressing various XIs in xylose media as the sole carbon source. Strains were cultured under aerobic conditions using YPX50 medium containing G418 (200 µg/mL). Cells for strain SS36 (blue), SS37 (red), SS38 (yellow green), SS39 (purple), SS40 (light blue), SS41 (orange), SS42 (dark blue), SS43 (brown) and SS44 (green) were initially inoculated at 0.1 U ODA600 and grown at 30 °C with shaking at 1000 rpm. Growth was measured using an Infinite 200 PRO microplate reader. Cell density was measured hourly. The dots indicate mean value of biological triplicates
