Biofuels, Bioproducts and Biorefining, EarlyView.Abstract The immobilization of lipase B from Candida antarctica (CALB) on an amino‐epoxy functionalized magnetic support (Fe3O4‐PEI‐DGEBA) resulted in a highly stable and efficient biocatalyst for biofuel production from tilapia oil. The synthesized support was characterized using scanning electron microscopy, transmission electron microscopy, X‐ray ...
