摘要
:研究了表面活性剂AOT的浓度及相体积比对AOT异辛烷反胶团体系提取脂肪酶的影响;随表面活性剂浓度增加提取率增大;表面活性剂浓度一定时,pH值低提取率高;提取率一定时,pH值低所需表面活性剂浓度也低.相体积比(V油V水)增大,提取率增大.初步探讨了提取机理.
The preliminary result of the yeast-lipase extracted by the reverse micelles system of AOT/iso-octane is reported in the paper. Under different pH values of the water phase, the influences of the surfactant (AOT)concentration and phase volume ratio on the extractive efficiency of the lipase are studied. The results indicate that with the surfactant concentration increasing the extractive efficiency is increased. When the surfactant concentration is constant, the extractive efficiency in creases with the pH value reduces. The extractive efficiency increases with the phase volume ratio increasing.
