Figure 4

Interaction effect plot of ammonia fiber expansion parameters, stover fraction and harvest period on monomeric sugar yields. Glucose yields are reported in part A and xylose yields are reported in part B, both of which are in terms of untreated dry biomass following 72 h enzymatic hydrolysis. MC = moisture content, RT = residence time, DWB = dry-weight basis, N = no xylanase added, Y = xylanase added (10% of total cellulase protein).
