File Name : fig. s1.tif

Caption : the percentage increase after 48h hydrolysis of cellulose derived from various pretreated lignocellulosic substrates after extensive delignification and hemicellulose removal (c-sp/op-cs, p, and lp: cellulose derived from steam and organosolv pretreated corn stover, poplar and lodgepole pine) by the reconstituted cellulase mixture (mix, cel7a, cel5a, and gh3 βg) with-and-without the addition of aa9 and gallate.

File Name : fig. s2.tif

Caption : the percentage increase after 48h hydrolysis of (a) holocellulose and cellulose derived from various pretreated lignocellulosic substrates after extensive delignification (dl-sp/op-cs, p, and lp: delignified steam and organosolv pretreated corn stover, poplar and lodgepole pine) and (b) dissolving pulp (dsp) with the supplementation of different portions of birchwood xylan by the reconstituted cellulase mixture (mix, cel7a, cel5a, and gh3 βg) with-and-without the addition of aa9 and gallate.

File Name : fig. s3.tif

Caption : to assess if there is a linear relationship between the percentage increase after 48h hydrolysis of steam pretreated (sp) and organosolv pretreated (op) corn stover (cs), poplar (p) and lodgepole pine (lp) with the cellulose accessibility of these substrates assessed by simons’ stain technique.

File Name : fig. s4.tif

Caption : the adsorption of cbm2a (high binding affinity to accessible crystalline cellulose), cbm44 (high binding affinity to accessible amorphous cellulose), and orange dye (simons’ stain technique) on various “model” cellulosic substrates. 
cnc: cellulose nanocrystals; dsp: dissolving pulp; pasc: phosphoric acid swollen cellulose; mc: mercerized cellulose; c iii: cellulose iii; cbm2a/cbm44: cellulose binding module family 2a/44.
