Effect of ammonia fiber expansion (AFEX) moisture content and residence time on enzymatic hydrolysis monomeric sugar yields. Base AFEX conditions: moisture content (60% dry-weight basis), ammonia loading (1.0 g NH3 g-1 dry biomass), temperature (90°C) and residence time (5 min). Yields are in terms of sugar available in untreated dry biomass. MC = moisture content, RT = residence time, Glu = glucose, Xyl = xylose, MTSY = maximum theoretical sugar yield.
