Journal ArticleDOI
Continuous enzymatic transesterification of high oleic sunflower oil in a packed bed reactor: influence of the glycerol production
TL;DR: In this article, the degradation of enzymatic activity was attributed to the formation of an hydrophilic hindrance around the enzyme resulting in diffusion limitations of the hydrophobic substrate from the organic phase to the enzyme.
Journal ArticleDOI
Kinetics of lipase-catalyzed esterification in supercritical co2
TL;DR: This study compares two solvents for enzymatic reactions: supercritical carbon dioxide (SCCO2) and organic solvent (n‐hexane) and suggests that activity was in the same range in both media.
Journal ArticleDOI
Comparison of lipase-catalysed esterification in supercritical carbon dioxide and in n-hexane
TL;DR: Stability of the lipase has been proved to be correct and similar in both solvents and inhibition by ethanol excess has been found but is greater in n-hexane, which can explain the higher initial velocities obtained in supercritical carbon dioxide for the highest ethanol concentrations.
Journal ArticleDOI
The role of silica gel in lipase-catalyzed esterification reactions of high-polar substrates
TL;DR: It was shown that the use of silica gel facilitates reactions at high glycerol concentrations without alteration of reaction rates or conversion yields and it also was demonstrated that highly hydrophilic polyols enhanced blockage of the enzyme.

TL;DR: The use of enzymes for technical applications has become increasingly important in different areas of biotechnology such as the food or pharmaceutical industries as discussed by the authors, and various processes have been developed using soluble or immobilized enzymes mainly in aqueous reaction phases.
