Figure 8

Correlation of compositional and assay results. (a) Glucan content versus xylan content; (b) sum of glucan and xylan content versus lignin content; (c) total sugar release versus lignin content; (d) reactivity versus lignin content. Samples are colored by feedstock type: CS, corn stover; CSG, cool season grass; MS, miscanthus; SG, sorghum; SW, switchgrass. Increasing lignin content was correlated with increasing xylan and glucan content, but also with decreasing total sugar release and reactivity (see text).
