Optimization of the Production of Enzymatic Biodiesel from Residual Babassu Oil ( Orbignya sp.) via RSM
Residual oil from babassu ( Orbignya sp.), a low-cost raw material, was used in the enzymatic esterification for biodiesel production, using lipase B from Candida antarctica (Novozym ® 435) and ethanol. For the first time in the literature, residual babassu oil and Novozym ® 435 are being investigat...
