text: Currently, most lignocellulosic biorefineries using enzymes to deconstruct plant polysaccharides will yield lignin-rich streams by either (i) extracting the plant carbohydrates to leave most of the lignin in the solid residue (72) or (ii) applying pretreatments to fractionate biomass to extract lignin (73) before carbohydrate conversion (Fig. 3).
