Figure 4
Effect of logR 0 on lignin recovery under (a) water-only and (b) 0.05% (w/w) H 2 SO 4 conditions. Solid squares = soluble lignin (10 mL/minute); open squares = insoluble lignin (10 mL/minute); solid triangles = soluble lignin (25 mL/minute); open triangles = insoluble lignin (25 mL/minute); solid circles = soluble lignin (62.5 mL/minute); open circles = insoluble lignin (62.5 mL/minute).
