Abstract

Aim: Due to lipases' regio-selectivity and ability to catalyze different reactions such as hydrolysis, esterification, and transesterification, the enzyme is attractive in biotransformation technology. Besides, another technology, namely enzyme immobilization, has attracted scientists/technologists' attention to employ immobilized Lipase in such a field. Thus Lipase of Candida rugosa was immobilized onto silica nanoparticles through adsorption. Furthermore, the immobilized biocatalyst was characterized and used to esterify ibuprofen enantioselectively.

Methods: To characterize immobilized Lipase onto silica nanoparticles scanning electron microscopy (SEM) and dynamic light scattering (DLS) were used.

Results: The catalytic properties of both immobilized and free lipases such as optima pH and temperature were not different. According to the results, the immobilized Lipase on silica nanoparticles showed 45% and 96% conversion (C) and enantioselectivity (ees), respectively. In comparison to free Lipase, the Immobilized Enzyme came with better catalytic activity.

Conclusion: Silica nanoparticles as one of the most promising Materials for the immobilization of Lipase in enantioselective esterification of ibuprofen, were introduced in this work.
