A composition for separation and recovery of hydrolytic enzymes from saccharified hydrolysates. The composition comprises flocculants for flocculating particulates. When added to saccharified hydrolysates, the composition flocculates the particulates thereby separating a separating a clarified supernatant that comprises the hydrolytic enzymes. The compositions comprise one or more of cationic polyacrylamides, lignins, lignin derivatives, sulfonated lignin derivatives and mixtures thereof. Suitable lignin derivatives can be recovered from organosolv pretreatment of lignocellulosic feedstocks. |
