• Abstract: Magnetic polymers supports have proven to be valuable materials for enzymeimmobilization, as they allow recovering the catalyst by magnetic separation,precluding the need for costly and time-consuming separation steps. In thisstudy, magnetic copolymer supports were synthesized using styrene (STY) anddifferent crosslinking agents (divinylbenzene, ethylene glycol dimethacrylate,or triethylene glycol dimethacrylate) and initiators (azobisisobutyronitrile orbenzoyl peroxide) and used to immobilize Candida antarctica lipase B(CALB). The aim was to obtain biocatalysts with high enzymatic activity andsatisfactory morphological properties for use in biotransformation reactions.Two morphological properties known to influence the immobilization yieldwere taken into consideration, specific surface area, and swelling index. Exper-imental data were compared to the predictions of a model based on molar bal-ance, method of moments, numerical fractionation, and elementary gelstructures. The high correlation (R2 = 0.9974) between experimental andpredicted values demonstrated the suitability of the model for estimating thetextural properties of enzyme supports. CALB was successfully immobilized,showing high hydrolytic activity (500–700 U g−1 ) and good thermal stability at50 C. CALB/STY-EGDMA-M was 14 times more stable than free CALB. Theresults confirm the efficiency of the immobilization method and the suitabilityof the copolymers for enzyme immobilization.
