Abstract	The effects of impacting factors, including cellulase loading, operation temperature, product glucose inhibition, and high solid pretreated biomass loading were examined systemically on the enzymatic saccharification of lignocellulose (dilute acid pretreated corn stover) in the presence and absence of tri-block copolymer L64 (also referred to polymeric nonionic surfactant). The complex kinetics of enzymatic saccharification of cellulose were subjected to fractal kinetic analysis based on a fractal kinetic model, which is described with fractal kinetic parameters of the rate constant and fractal exponent. The results indicate that glucose inhibition including high lignocellulose loading is indexed by decreasing rate constant while lignin inhibition and high operation temperature is indexed by increasing fractal exponent. The effect of a nonionic surfactant on the enzymatic saccharification of lignocellulose mainly contributed to the elimination of lignin inhibition by decreasing the corresponding fractal exponent. However, the effect of the nonionic surfactant on cellulase activity and stability was very limited.
