Abstract

Various inorganic oxide materials coated with 3-aminopropyltriethpxysilane and glutaraldehyde were examined as support materials for lipase catalysing the hydrolysis of rapeseed oil. Nine commercial glass products of different structure and surface area and magnetite were compared. Hydrolytical activity of channel-like carriers was 100× higher than that of controlled pore glass, glass cloth and powders. Lipase on magnetite was tested in hydrolysis of oil in industrial waste having viscosity of 30mPa.s. After 100% conversion of oil the lipase on magnetite was separated in magnetic field and reused 7× without decrease of activity.
