Summary The adsorption behaviour of cellulase fromTrichoderma viride on microcrystalline celluloses with different specific surface areas was studied. The adsorption was found to fit a Langmuir isotherm. There was an increase in the maximum adsorption amount (Amax) as the specific surface area of microcrystalline cellulose increased. The values of Amax and adsorption equilibrium constant (K) decreased with increasing temperature. Thermodynamic parameters in adsorption were calculated from K. It was found from the enthalpy of adsorption, that van der Waals-Type interaction was responsible for adsorption of cellulase on microcrystalline cellulose. The adsorption process was exothermic and an adsorption enthalpy-controlled reaction.
