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

Figure 5

Total reactivity (fraction of glucan and xylan originally present in biomass feedstock, both structural and nonstructural, released as glucose or xylose) from dilute acid pretreatment alone (hollow symbols) and pretreatment followed by enzymatic hydrolysis (filled symbols) as a function of pretreatment severity. (a) Corn stover; (b) poplar; (c) switchgrass; (d) biomass sorghum. Experimental conditions were the same as in Figure 2. The yield calculations are based on both structural and non-structural contributions (for example, cellulose, starch, sucrose; see text).
