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 the 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, lipase activity gradually reduced with increase in surfactant concentration. At low concentration of the latter, the activity was well maintained and removal of triolein was promoted by hydrolysis. At high concentration, the activity was inhibited and triolein was removed by solubilization. Removal of triolein by hydrolysis was noted to be more efficient than by solubilization. In the lipase-AOS or AE2S system, triolein was removed very much at both high and low surfactant concentrations. This was due to the effective maintenance of lipase activity and solubilization resulting from surfactant cmc.
