AbstractEnzymatic hydrolysis is the essential step in the production of II generation biofuels made from lignocellulosic biomass, i.e. agricultural and forestry wastes. The efficient enzyme-catalyzed degradation of cellulose and hemicellulose to monosaccharides requires the synergistic action of the independent types of enzymes. The basic aim of the study was to experimentally determine the activity of two commercially offered cellulolytic enzyme preparations: Cellic®CTec2 and the mixture of Celluclast®1.5L and Novozyme 188 in the hydrolysis of lignocellulosic biomass: energetic willow and rye straw, as well as cellulose paper used as a feedstock. Before hydrolysis, the biomass was subjected to alkaline pre-treatment at high-temperature (121°C) and high-pressure (0.1 MPa) conditions. Based on the results, the influence of the type and concentration of enzymes on the effectiveness of hydrolysis was evaluated and finally the enzyme activities were determined for each of tested cellulolytic preparations.
