Abstract

In this paper, we report a comprehensive kinetic study on esterification of lauric acid with lauryl alcohol catalyzed by commercial porcine pancreatic lipase (PPL) in the form of cross-linked enzyme crystals (CLEC) using glutaraldehyde as thecrosslinker.ThestabilityoftheCLECwasbetter thantheimmobilized enzymefor practicalapplications.Comparative studies using six different solvents having hydrophobicity (log p) values ranging from 0.70 to 3.50 revealed that the esterification reaction was favoured in hydrophobic solvents. The kinetics of the esterification reaction conformed with the so-called Ping-PongBi-Bi mechanism with alcohol inhibition.
