摘要：

In order to investigate the interactive adsorption behaviors between each cellulase component purified from Trichoderma viride cellulase on microcrystalline cellulose, the adsorption of CMCase, Avicelase, and various compositions of CMCase and Avicelase was performed at 25-45-degrees-C. All adsorptions were found to apparently obey the Langmuir isotherm and the thermodynamic parameters, DELTA-H(a), DELTA-S(a), and DELTA-G(a) were calculated from the adsorption equilibrium constant, K(ad). The adsorption process was found to be endothermic and an adsorption entropy-controlled reaction. The amount of adsorption of cellulase components decreased with increasing temperature and varied with a change in composition of the cellulase components. The maximum synergistic degradation occurred at the specific mass ratio of the cellulase components at which the maximum affinity of cellulase components occurred.
