文摘

Poly-(styrene-divinylbenzene) resin was used in the adsorption of microbial lipase. The effect of certain factors on the adsorption process was evaluated. Maximum immobilized protein concentration was around 134 mg/g of support. Kinetic, isotherm, mechanism and thermodynamic studies were performed. The biocatalyst exhibited high activity and operational stability in ester synthesis.
