Figure 2

Content of lignin, acetate, and total polymeric and oligomeric neutral polysaccharides in alkaline pre-extraction liquors as a function of solids loading during alkaline pre-extraction. Pre-extraction was performed at 0.08 g NaOH per g corn stover, at 80°C for 1 h and results show a maximum extraction of cell wall biopolymers at 10% (w/v) solids, which is likely a consequence of imperfect alkali penetration into the biomass at 20% (w/v) solids because of the limitations of the laboratory-scale mixing.
