Volume-based particle-size distribution during agitation and subsequent enzymatic hydrolysis. Material used: spruce at 13% WIS. (A) Agitation for 48 hours at 600 rpm followed by 48 hours of agitation at 100 rpm. (B) Agitation for 96 hours at 100 rpm. (C) Agitation for 48 hours at 600 rpm followed by hydrolysis for 48 hours at 100 rpm (only hydrolysis shown). (D) Agitation for 48 hours at 600 rpm followed by hydrolysis for 48 hours at 600 rpm (only hydrolysis shown). Markers: dash line represents 0 hours, two dash line represents 24 hours, filled circles represents 48 hours, x represents 50 hours, and empty circles represents 96 hours.
