Lipase from Candida Rugosa was physically attached to Mg modified Fe2O4 nanoparticles (NPs) and employed in the conversion of Brewers' spent grains (BSGs) into biodiesel, in the presence of methanol. The proposed strategy explored the direct immobilization of the enzyme on the as prepared oleic acid modified NPs. In addition, a large amount of enzyme was bound on the NPs, allowing their efficient recycling by using an external magnet. A better yield was achieved at 1:4 oil/methanol molar ratio after 48 h at 45°C reaction temperature. The nanocatalyst exhibits also a good recyclability. The biodiesel produces was analyzed according with EN 14214.

Abstract
Lipase from Candida Rugosa was physically attached to Mg modified Fe2O4 nanoparticles (NPs) and employed in the conversion of Brewers' spent grains (BSGs) into biodiesel, in the presence of methanol. The proposed strategy explored the direct immobilization of the enzyme on the as prepared oleic acid modified NPs. In addition, a large amount of enzyme was bound on the NPs, allowing their efficient recycling by using an external magnet. A better yield was achieved at 1:4 oil/methanol molar ratio after 48 h at 45°C reaction temperature. The nanocatalyst exhibits also a good recyclability. The biodiesel produces was analyzed according with EN 14214.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
