Abstract
To synthesis biodiesel from palm oil in one-time addition of methanol and solvent-free medium using CBD fused with C-terminal of lipase from G. stearothermophilus (GSlip-CBD) was immobilized onto magnetic cellulose nanosphere (MCNS). The immobilized matrix traits were preconceived by FT-IR, TEM and XRD. Perceptible biodiesel yield 98 and 73% was synthesized by GSlip-CBD-MCNS in 4â¯h and GSlip-MCNS in 6â¯h under the optimized conditions of oil:methanol ratio (1:3.5), temperature (55 and 50â¯Â°C) and enzyme loading (15â¯U). Intriguingly, the operational stability of GSlip-CBD-MCNS was an easily attainable owing to the magnetic properties and could be reused up to 8th and19th cycles with 94 and 45% of biodiesel yield respectively, compared to GSlip-MCNS. Thus GSlip-CBD-MCNS could be a potential biocatalyst for higher yield of biodiesel and reusability in one step addition of methanol.
