Hence the kinetics of the enzymatic reaction was studied on-line. Through the resolution of the experimental data matrix, the formation and decay of the intermediate was found to be first-order reactions. The rate constants of the two steps of reaction were obtained. Calculated results were compared with experimental data, which showed the reliability of the resolution as well as the limitation of some traditional methods on dealing with such a on-line-analysis problem. 漆酶 反应中间体 反相胶束 Laccase intermediate reverse micelle O643.3 国家自然科学基金资助项目 （ 2 9775 0 5 1） 2003-02-01 2021-04-01 2
