At the same temperature, k〓 in the reversed micelles was always less than k＇〓 in the buffer. According to the thermodynamic analysis for inactivation of penicillin amidase in the reversed micelles, the free energy of activation was increased by 2. 71%, while the entropies and enthalpies of activation were decreased, corresponding to 63. 9% and 76. 9% of that in pure buffer respectively.

由热力学分析可知，青霉素酰化酶在AOT/异辛烷反胶团中的热失活过程，与水溶液中相比，活化自由能△G〓增加了2.71％，而活化熵△S〓和活化焓△H〓分别减小为原来的63.9％、76.9％，从而使酶热稳定性平均提高了2～4倍。
