Resumen:
|
Several approaches towards the efficient immobilization of poly-3-hydroxybutyrate (PHB) depolymerase from Streptomyces ascomycinicus (PhaZSa) on magnetic-silanized nanoparticles have been explored in order to accomplish the preparation of an active immobilized biocatalyst in PHB hydrolysis in acid conditions. A simple non-covalent adsorption of PhaZSa to silanized magnetic particles at acidic pH during a short incubation time allowed the preparation of immobilized biocatalysts with increased specific activity. In contrast, covalent binding of PhaZSa to silanized magnetite by different methods led to immobilized biocatalysts whose retained activity were low or void.
