Figure 4From: The enzymatic hydrolysis of pretreated pulp fibers predominantly involves “peeling/erosion” modes of actionChanges in the average fiber width of pretreated woody biomass over the course of hydrolysis of size-fractionated steam and organosolv pretreated pulp fibers. The height of the bars represents the range/variability of the average fiber width in the sample (95% confidence interval).Back to article page
