以羧甲基纤维素钠（CMC）为底物评价纤维素酶的活性，研究了不同条件下静磁场对酶的活性及构象的影响。9℃，pH4．0条件下磁化，其活性及荧光光谱均不见明显变化；但若改变反应时的pH，可使活性增加达16.4％；并发现磁处理后的酶有滞后效应及可逆性。较高温度下，磁化处理酶液，其活性及构橡均发生不同程度的变化，且对其抑制动力学表现为混合型抑制模式；其构象变化也基本上随失活的增加荧光强度增大。
The activity of cellulase was evaluated by using carboxymethylcellulose sodium (CMC) as substrate, and the effect of static magnetic field on the activity and conformation of the enzyme under different conditions was studied. At 9 ℃ and pH 4.0, there was no significant change in the activity and fluorescence spectra. However, if the reaction pH was changed, the activity increased by 16.4%. And the magnetically treated enzyme showed hysteresis and reversibility. At higher temperature, the enzyme activity of magnetization and the rubber-forming all changed in different degrees, and the inhibition kinetics showed a mixed inhibition mode; the conformational change basically also increased with the increase of inactivation fluorescence intensity .
