Synthesis of Biolubricants Catalyzed By Lipase B from Candida Antarctica Immobilized on a Magnetic Lignin Based Support Derived from Cashew Apple Bagasse

Short Introductive summary

This study investigated the production of isoamyl oleate (AO-ISO), a biolubricant, through esterification reactions catalyzed by Candida antarctica lipase B (CALB) immobilized on a composite of cashew apple bagasse lignin conjugated with magnetic nanoparticles (Lig-NMP). Lig-NMP showed as a low-cost and easy-handle support for CALB, due to the use of a residue from the cashew apple juice process and its magnetic properties. This research explores the synthesis of a biolubricant using oleic acid and fusel oil (FO), a byproduct of sugarcane fermentation, and also using fatty acids from vegetable oils (soybean, canola, sunflower, cottonseed, and olive), in a solvent-free reaction medium. The optimal conditions for AO-ISO synthesis in the presence of oleic acid were determined and the conversions were higher than 80% and the ester showed high purity, with the best results obtained using immobilized enzyme compared to free CALB. Canola and olive oil fatty acids stand out in biolubricant production. The results suggest a promising and sustainable approach, using industrial by-products for AO-ISO synthesis with potential industrial applications.
