Fig. 5From: Gaseous ammonia pretreatment lowers the required energy input for fine milling-enhanced enzymatic saccharification of switchgrassComparison of monomeric glucose (left) and xylose (right) yields at 14 and 25 % solids loading after 72 h saccharification as a function of milling time using ¼″ stainless steel beads for the ammonia-treated samples of Fig. 4. Saccharification was carried out as in Fig. 4 Back to article page
