为了研究从绿色木霉纤维素酶纯化的各纤维素酶组分在微晶纤维素上的相互吸附行为，在25-45 ℃下进行CMCase、Avicelase以及CMCase和Avicelase的各种组合物的吸附。发现所有吸附显然遵守Langmuir等温线，并且从吸附平衡常数K（ad）计算热力学参数Δ H（a）、Δ S（a）和Δ G（a）。吸附过程是吸热的，是吸附熵控制的反应。纤维素酶组分的吸附量随温度的升高而降低，并随纤维素酶组分组成的变化而变化。协同降解最大值出现在特定的纤维素酶组分的质量比时，在该质量比下，纤维素酶组分的亲和力最大。
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.
