Immobilization and Stabilization of Acylase on Carboxylated Polyaniline Nanofibers for Highly Effective Enzymatic Antifouling |
초록 |
Acylase (AC) was immobilized and stabilized on carboxylated polyaniline nanofibers for the development of antifouling nanobiocatalysts with high enzyme loading and stability. AC was immobilized via three different approaches: covalent attachment (CA), enzyme coating (EC), and magnetically separable enzyme precipitate coating (Mag-EPC). The activity of Mag-EPC was 75 and 300 times higher than that of those with CA and EC, respectively. After incubation under shaking at 200 rpm for 20 days, Mag-EPC maintained 55% of its initial activity, whereas CA and EC showed 3 and 16% of their initial activities, respectively. The antifouling of Mag-EPC against the biofilm formation of Pseudomonas aeruginosa was tested under static- and continuous-flow conditions. The biofilm formation in the presence of Mag-EPC under static- and continuous-flow condition was lower than that under no addition of Mag-EPC. |
