• Adsorption characteristics of different activities in a crude cellulase solution derived from Trichoderma reesei D1-6 on lignocellulosic materials such as rice straw and bagasse were studied and compared with the adsorption on micro-crystalline cellulose powder and Solka Floc. The effect of particle size reduction, temperature and enzyme concentration on the adsorption of cellulase were also studied. The three activities of the enzyme against filter paper, carboxymethyl cellulose and p-nitrophenyl-β-D-glucoside were all adsorbed on the cellulose surface. Crystallinity index and the amount of enzyme adsorbed showed no correlation. Varying particle size and temperature had only a limited effect on the adsorption of these enzyme activities. A Langmuir adsorption isotherm type equation satisfactorily related the adsorbed enzyme activity to the free enzyme activity in a mixture.
