Hydrolysis of Avicel using CTec2 at 5% dry matter at 24, 48, and 96 h with (A) different molecular weight of PEG (1% w / w ) in water and (B) different concentrations (molar concentration and percentage weight per gram of cellulose) of PEG. The control hydrolysis contained no PEG and was conducted in water (open symbols), and the T2 relaxation times of the hydrolysis liquid fraction at the onset of hydrolysis are shown in parenthesis next to the legend. PEG, polyethylene glycol.
