To enhance the cellulase activity for the reaction of water-insoluble substrates, the diisooctyl succinate sodium sulfonate (AOT)/isooctane reverse micellar was modified by co-adsorption of Triton X-100. An appreciable increase of cellulase activity was observed and the results show that the optimal molar fraction of AOT/Triton X-100 is 0.20. The influences of other reaction conditions on the molar ratio of water to total surfactants (<I>W</I><sub>o</sub>), different pH and temperature have been investigated, and the optimal conditions for the reaction were <I>W</I><sub>o</sub>3.3, <I>T</I>315.11 K, pH5.10.

Key words: mixed reverse micelles, thermokinetic, reduced extent method, microcalorimetry
