Conclusions: physical immobilization of hrp on iron magnetic nanoparticles improved the stability toward the denaturation induced by ph, heat, metal ions, urea, detergent, and water-miscible organic solvent.
The synthesis of new collagen, chitosan and chitosan-collagen coated magnetic nanoparticles have been done two types of cross-linkers for polymer shell stabilization were used: glutaraldehyde (gla) as a standard cross-linker and new one – squaric acid (sqa) structure and morphology of prepared nanoparticles were characterized by atr-ft ir, xrd and tem analysis. Catalysts 2017, 7, 26 3 of 14 and with sqa as a new crosslinking agent four types of prepared nanoparticles are novel all of the prepared magnetic nanomaterials were used for covalent immobilization of lipase from candida rugosa. A commercial amylase (amy) was immobilized by adsorption onto luffa operculata fibers (lofs) the derivative lof-amy presented capacity to hydrolyze starch continuously and repeatedly for over three weeks, preserving more than 80% of the initial activity this system hydrolyzed more than 97% of starch during 5 min, at room temperature.
