Immobilization yield was determined to be 70%. The cresolase and catecholase activities of enzyme immobilized at optimum immobilization conditions were found to be 13.3 and 670 U g beads minen10.3109/10731191003790406info:eu-repo/semantics/openAccessCynara-Scolymus L.L-Dopa ProductionTyrosinaseGelHeadsPurificationStabilityArticle383157163Q4WOS:0002772648000072-s2.0-7795202394620429683N/A
