Lipases were immobilized by covalent binding onto epoxy-functionalized silica. The immobilized lipases were studied for production of biodiesel from waste cooking oil. A mixture of 1,3-specific lipase (RML) and nonspecific lipase (CALB) was used. The effect of water, t-butanol and blue silica gel on the FAME% was considered. Epoxy-functionalized silica resulted to high catalytic activity.
