  • Magnetic carrier and membrane bioreactor comprising enzyme for inhibiting biofilm formation
    Patent number: 7867392
    Abstract: A technique for inhibiting biofouling caused by biofilms grown on a material surface of a water system where microorganisms exist such as the membrane surface of a membrane bioreactor (MBR) for advanced wastewater treatment is disclosed. Specifically, a magnetic carrier comprising an enzyme for quenching quorum sensing that inhibits biofilm formation, a membrane bioreactor system that can be stably operated without inactivation and loss of enzymes and a method for inhibiting biofilm formation are described.
    Type: Grant
    Filed: November 17, 2008
    Date of Patent: January 11, 2011
    Assignee: SNU R&DB Foundation
    Inventors: Chung-Hak Lee, Kyung-Min Yeon
