Kamel Ariffin, Maryam Farhana published the artcileFeCl3.6H2O Chitosan coated superparamagnetic nanoparticles supporting lipase enzyme from Candida Antarctica for microwave assisted biodiesel production, Recommanded Product: Methyl docosanoate, the main research area is Chitosan superparamagnetic nanoparticles microwave assisted biodiesel production.
Biocatalysis has emerged as a green technol. in chem. based catalysis. Immobilization of enzymes onto magnetized nanomaterials enhances downstream processing as it eases their separation from reaction mixture Synthesis of the nanoparticles was performed in an aqueous solution of FeCl3.6H2O as precursor and NH3 as nucleating agent under microwave irradiation The maghemite complex was crosslinked with glutaraldehyde to provide conducive environment for enzyme immobilization. Stability of produced immobilized lipases against different conditions were evaluated such as working temperatures from 27°C to 85°C and retained more than 64% of its activity at 85°C. The immobilized lipase complex was able to withstand a wide range of acidic to alk. environment from pH 5.5 to pH 9.5. The enzyme retains more than 59% of its activity after 14 days of storage and can be recycled for more than 7 cycles with remaining high activity at 93.7%. Developed enzyme was then subjected to microwave irradiation for transesterification of palm oil to produce biodiesel. Highest biodiesel recovery achieved from microwave assisted immobilized lipase catalyzed transesterification of palm oil was 70.2%. The phys. properties of produced biodiesel was evaluated and fulfilled the ASTM general requirement for fuels.
