Resumen:
Candida antarctica lipase B was immobilized for the first time (at the author´sknowledge) onto linear low density polyethylene (LLDPE) films. Polymer filmswere previously bonded to a commercial aluminum sheet using a simple supportpreparation method. Biocatalyst performance was evaluated in penthyl oleatesynthesis at room temperature. Two different catalyst geometries were testedand compared: one aluminum-polyethylene 50 mm × 50 mm foil(50CAT) or near 5 mm × 5 mm aluminum-polyethylene foils(5CAT). The obtained results demonstrate that the biocatalyst obtained with50 mm × 50 mm aluminum-polyethylene foil or 50CAT isreusable in up to 7 cycles, easy to separate from reaction products, andeconomical in comparison with commercial Novozym 435. Novel and economicalCALB/LLDPE/Al biocatalyst is an attractive alternative for possibleapplications in a continuous monolithic reactor and future industrial scalingup.
