From: A laboratory-scale pretreatment and hydrolysis assay for determination of reactivity in cellulosic biomass feedstocks

Figure 3

Total (sum of monomeric and oligomeric) glucose release (fraction of biomass feedstock sample dry weight released as glucose) from dilute acid pretreatment alone (hollow symbols) and pretreatment followed by enzymatic hydrolysis (filled symbols) as a function of pretreatment temperature. (a) Corn stover; (b) poplar; (c) switchgrass; (d) biomass sorghum. Experimental conditions were the same as in FigureĀ 2. Some glucose was released during pretreatment; the horizontal line in each plot shows the amount of non-structural glucose, derived from starch and sucrose (see text).
