Immobilization of Candida rugosa lipase on hydrophobic/strong cation-exchange functional silica particles for biocatalytic synthesis of phytosterol esters

[Display omitted] ► Mixed-mode silica particles functionalized with octyl and sulfonic acid groups were prepared. ► Candida rugosa lipase was immobilized on the silica particles via hydrophobic and strong cation-exchange interaction. ► The immobilized lipase exhibited better thermal stability and re...
