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。

The deactivation rates of penicillin amidase in both systems follow the first-order model. The inactivation rate constants increased gradually and α decreased slightly, with the increase of temperature.

随着温度的升高，失活速率常数k〓和k＇〓逐渐增大，α略有所降低；当体系温度相同时，该酶在反胶团中的k〓值比水溶液中的k＇〓小。
