· The amount of cellulose in lignocellulosic biomass depends mainly on the feedstock. As an example, the typical amount of cellulose in wood averages from 40 to 50% whereas the amount varies between 16 and 41% in bark [ 15, 16 ]. In wheat, barley and triticale straw, the cellulose content is in the 30–45% range [ 17 ].
