제목 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.
