Immobilization yield was 78%. First, optimum immobilization conditions were determined, and morphology of chitosan beads was characterized by scanning electron microscopy. Optimum pH and temperature were evaluated as 6.0 and 40 degrees C, respectively. The immobilized beads saved about 55% of its activities at 60 degrees while saved about 32% at 70 degrees C for 30min. V-max/K-m values were determined as 31.75 and 2.87 using olive oil as substrate for immobilized beads and free enzyme, respectively. Immobilized beads showed the activities during 30 days at+4 degrees C.en10.1080/21691401.2016.1182920info:eu-repo/semantics/openAccessChitosanImmobilizationIonotropic Gelatin MethodLaurelLipaseTripolyphosphateCandida-Rugosa LipaseImmobilizationAlginateAcidNanoparticlesSupportOilOptimizationPurificationHydrolysisArticle455864870Q2WOS:0004020394000022-s2.0-8496720576227181370Q1
