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 ,p H值低提取率高 ;提取率一定时 ,p H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。
The preliminary results ofthe yeast- lipase extracted by the reverse micelles system of AOT/iso- octane are reported in the paper.Under differentp H values of the water phase,the influences of the sur- factant(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 increases. When the surfactantconcentration is constant,the extractive efficiency increases with the p H value reduc- ing.The extractive efficiency increases with the phase volume ratio increasing.
