The optimum immobilization conditions were determined as enzyme concentration of 12% (v/v) and immobilization time of 24 h. Transesterification reaction was performed using enzymatic catalysis for the production of fatty acid methyl ester from waste frying oil. The results indicate that 60% yield of fatty acid methyl ester was obtained under optimum immobilization conditions. Operational stability was determined with immobilized lipase and it indicated that 74% residual activity occurred after using repeatedly for five consecutive batches of 24 h each.eninfo:eu-repo/semantics/closedAccessCandida antarcticaEnvironmental sciences & ecologyChitosanEnergy & fuelsFatty acid methyl esterSelectivityImmobilizationEngineeringWaste frying oilTransesterificationCovalent immobilizationHydrogen-peroxideBiodiesel productionEnzymatic conversionRugosa lipaseHorseradish-peroxidaseFuelCandidaChitosanEstersEnzyme immobilizationIsomersYeastCandida antarctica lipase AEnzymatic catalysisTransesterification reactionEnzyme concentrationsOperational stabilityFatty acid methyl esterImmobilized lipaseImmobilization conditionsArticle0003423150000012-s2.0-84908530270231323193621Energy & fuelsEnvironmental sciencesEngineering, chemicalBiodiesel Production; Triacylglycerol Lipase; Pseudozyma Antarctica
