Note: [Glc]IL or [Xyl]IL is glucose or xylose concentration in the IL phase; [Glc]NaOH or [Xyl]NaOH is glucose or xylose concentration in NaOH phase; ND: not detected. a The standard deviation is within 20% of the measurement. The deviation is due to the low concentration of the sugars in IL phase and detection limit of the instrument. bGYNaOH is the final glucose yield in NaOH phase (percentage of the glucose in original biomass); XYNaOH is the final xylose yield in NaOH phase (percentage of the xylose in original biomass).
