Do Enzymatic Hydrolyzability and Simons' Stain Reflect the Changes in the Accessibility of Lignocellulosic Substrates to Cellulase Enzymes?
TL;DR: The inaccessibility of the cellulose to the enzymes appears to be the primary reason for the lower susceptibility of the dried pulps to enzymatic hydrolysis.
