Abstract

To improve the conversion of enzymatic hydrolysis of biomass in an energy-efficient manner, two shorttime ultrasonication strategies were applied on six types of biomass with different structures and components. The strategies include pre-sonication before the hydrolysis and intermittent sonication during the ongoing hydrolysis. The microstructures of each type of biomass were characterized by scanning electron microscopy to investigate the potential correlation between biomass structure and ultrasonicaton. The concentration of resultant reducing sugar was measured to evaluate the efficiency of the hydrolysis. The results indicate that hydrolysis efficiency greatly depends on the initial structures of biomass and that shorttime ultrasonication can yield up to 27.5% improvement in hydrolysis efficiency with only 120 s of sonication.
