| Research Abstract |
The relative activity of lipase, solubilization of Yellow OB and removal of triolein were determined to clarify the effects of hydrolysis by lipase and solubilization on removal of triolein in the lipase-surfactant system. Three kinds of lipases from Candida cylindracea, Fusarium sp. and Chromobacterium viscosum were used.
In the lipase- SDS or LAS system, the activity of lipase was gradually reduced as the concentration of the surfactant was increased. When the concentration of the surfactant is low, the activity of lipase was well maintained and the removal of triolein was promoted by hydrolysis. On the other hand, in case that the concentration of the surfactant is high, the activity was inhibited and triolein was removed by solubilization. It was found the removal by hydrolysis was higher than that by solubilization.
In the lipase-AOS or AE_2S system, triolein was highly removed in both high concentration and low concentration of the surfactant. This is explained by good maintaining of the activity of lipase and solubilization caused by low cmc of the surfactant.
