High-solids enzymatic hydrolysis of steam-exploded willow without prior water washing
A laboratory reactor equipped with a screw press was used for the hydrolysis of steam-SO2-exploded willow Salix caprea by a composition of Trichodemma reesei and Aspergillusfoetidus enzyme preparations at high substrate concentration. Optimal conditions providing the maximal volume of hydrolysis syrup with maximal sugar concentrations were determined. Two different hydrolysis procedures were devel
