Summary: The arrangement and type of support significantly affects the efficiency of immobilized enzymes. 1-dimensional fibrous materials are desirable supports due to their high surface area to volume ratio and internal porosity, allowing for increased enzyme loading and better catalytic efficiency. Electrospun nanofibers offer protection for enzymes against harsh conditions and a potential increase in stability, making them a promising avenue for enzyme immobilization research.

Summary: A second polymer layer was spontaneously grafted onto the surface of polydopamine-coated magnetic particles using dia-minopolyethylene glycol without the need for an activating agent. The immobilized fi-galactosidase showed higher thermal stability and a higher optimal temperature compared to the free enzyme. The apparent Km and Vmax values for the immobilized enzyme were slightly higher than those of the free enzyme. The immobilized fi-galactosidase retained 94% of its activity after 96 hours of continuous operation in lactose hydrolysis.
