Abstract
The lipase from Candida rugosa was first immobilized on macroporous adsorption resins, then coated with glutamic acid didodecyl ester ribitol amide as a catalyst for esterification of lauric acid and lauryl alcohol in (organic) solvents. The resin AB-8 was proved to be the best carrier and isooctane was the most suitable solvent.The specific activity of the surfactant-coated immobilized lipase was 1.6 to 1.9 times higher than that of the uncoated immobilized lipase.
