Lipase from Thermomyces lanuginosus (TLL) was immobilized via physical adsorption on mesoporous poly-(styrene-divinylbenzene) resin (PSty-DVB). The influence of pH, ionic strength, temperature, initial protein loading, and contact time on the adsorption process and catalytic properties of the biocatalysts was systematically investigated. The catalytic properties of the biocatalysts were detentined in the hydrolysis of olive oil emulsion and immobilized protein concentration. Maximum adsorption capacity of 133.9 +/- 1.3 mg of protein/g of support using initial protein loading of 150 mg/g was observed after 900 min of incubation at 5 mM buffer sodium acetate pH 5.0 and 25 degrees C. This biocatalyst presented hydrolytic activity of 443.0 +/- 25.2 IU/g of support. Moreover, high esterification activity and operational stability in cetyl linoleate (wax ester) synthesis in a solvent-free system (conversion of 90.5 +/- 0.6% after five cycles of reaction of 30 min each) was also observed. This biocatalyst showed better catalytic activity than commercial immobilized TLL (Lipozyme TL-IM) in wax ester synthesis (conversion, approximate to 87% after 120 min of reaction). Thermodynamic analysis showed that the immobilization was a spontaneous and a physisorption process. The equilibrium adsorption data were fitted to the Sips isotherm model. The results of kinetic study showed that the adsorption process was described by a pseudo-first-order model. This process was influenced by intraparticle and film diffusion. Attenuated total reflection Fourier transform infrared (ATR-FTIR) and scanning electronic microscopy (SEM) analyses were also performed to confirm the adsorption of the enzyme on the support surface.
