Both acid pretreatment (AP) and enzymolysis (EL) of corn stover were characterized.
- class="label">•
AP decreased hemicellulose from 19.7% in raw substrate to 9.28%.
- class="label">•
AP increased pore volume from 0.0067 cm3/g in raw substrate to 0.019 cm3/g.
- class="label">•
Enzyme adsorption in AP substrate was three-fold higher than that in raw substrate.
- class="label">•
EL proceeded in the parallel hydrolysis mode of crystalline/amorphous cellulose.
