Laccase was immobilized by physical adsorption on several SBA-15 with different textural properties and by covalent attachment on functionalized SBA-15 prepared by co-condensation method (direct synthesis). The adsorption of laccase was partially reversible and showed some degree of lixiviation. However, covalently attached laccase to aminopropyl and aminobutyl functionalized SBA-15 exhibited important activity for the degradation of naphthalene with, respectively, 35% and 39%wt of removal in 5 hours. The aminopropyl biocatalyst retained higher activity after repeated uses than the corresponding aminobutyl.enAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Medio Ambienteinfo:eu-repo/semantics/article10.1016/j.biortech.2010.06.042info:eu-repo/semantics/openAccess23 Química
