Figure 5From: Effects of agitation on particle-size distribution and enzymatic hydrolysis of pretreated spruce and giant reedSurface-weighted mean diameter (D 3,2 ) during enzymatic hydrolysis at different impeller speeds. (A, B) Spruce at 13% WIS. (C, D) Giant reed at 13% WIS. Markers: Diamond represents 600 rpm, square represents 300 rpm, and circle represents 100 rpm. WIS, water-insoluble solids.Back to article page
