Effect of ammonia fiber expansion (AFEX) pretreatment ammonia loading and xylanase addition on enzymatic hydrolysis monomeric sugar yields. Glucose yields are reported in part A and xylose yields are in part B. All AFEX runs were kept at constant moisture content (60% dry-weight basis), temperature (90°C) and residence time (5 min). Yields are in terms of sugar available in untreated dry biomass.
