Effect of solvents on hydrolysis of olive oil by immobilized lipase in reverse phase system

Summary Lipase fromCandida rugosa was immobilized by adsorption on three supports which could contain water available for the hydrolysis of olive oil in a reverse phase system. To select the most suitable solvent for this system, the effect of organic solvents on the stability and catalytic activity of immobilized lipase for the hydrolysis reaction has been examined. The results revealed that isooctane was superior to any other solvents tested in this study for enzymatic fat splitting in a reverse phase system. Also the effect of the solvent polarity on the hydrolysis of olive oil has been examined in detail using various organic solvents mixed with an equivolume of isooctane. It was found that the hydrolysis of olive oil by immobilized lipase was markedly affected by the polarity of reaction solvents.
