Studies in the Area of Macromolecular Research Reported from Pohang University of Science and Technology

May 30, 2014



By a News Reporter-Staff News Editor at Science Letter -- Current study results on Macromolecular Research have been published. According to news reporting originating from Pohang, South Korea, by NewsRx correspondents, research stated, "Highly effective antifouling was achieved by immobilizing and stabilizing an acylase, disrupting bacterial cell-to-cell communication, in the form of cross-linked enzymes in magnetically separable mesoporous silica. This so-called 'quorum-quenching' acylase (AC) was adsorbed into spherical mesoporous silica (S-MPS) with magnetic nanoparticles (Mag-S-MPS), and further cross-linked for the preparation of nanoscale enzyme reactors of AC in Mag-S-MPS (NER-AC/Mag-S-MPS)."

Our news editors obtained a quote from the research from the Pohang University of Science and Technology, "NER-AC effectively stabilized the AC activity under rigorous shaking at 200 rpm for 1 month, while free and adsorbed AC lost more than 90% of their initial activities in the same condition within 1 and 10 days, respectively. When applied to the membrane filtration for advanced water treatment, NER-AC efficiently alleviated the membrane surface, thereby enhancing the filtration performance separable NER-AC, as an effective and sustainable antifouling m for water reclamation. biofilm maturation of Pseudomonas aeruginosa PAO1 on the membrane surface, thereby enhancing the filtration performance by preventing membrane fouling."

According to the news editors, the research concluded: "Highly stable and magnetically separable NER-AC, as an effective and sustainable antifouling material, has a great potential to be used in the membrane filtration for water reclamation."
