Synthesis of biofuel esters catalyzed by lipase B from Candida antarctica immobilized on a magnetic lignin‐based support derived from cashew apple bagasse

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study investigated the biosynthesis of ethyl oleate (EO), the main constituent of biodiesel, via the esterification of oleic acid with ethanol, catalyzed by Candida antarctica lipase B (CALB) immobilized on a low‐cost support derived from cashew apple bagasse (CAB) lignin.
