  • Method and measuring device for determination of the growth rate of biofilm
    Patent number: 10520488
    Abstract: A method for determination of the growth rate of biofilm using an electrical impedance analyses is disclosed. The method comprises the steps of: bringing a culture medium fluid in contact to an electrode structure, having biofilm grown within the fluid culture medium with the biofilm arranged in distance to the electrodes structure, so that the fluid culture medium is placed between the growing biofilm and the electrode structure; measuring the impedance of the electrodes structure over a monitoring time, and determining the growth rate of the biofilm as a function of the reduction rate of the impedance values measured on the electrode structure.
    Type: Grant

    Date of Patent: December 31, 2019
    Assignee: Helmholtz-Zentrum fuer Infektionsforschung GmbH
    Inventors: Jost Van Duuren, Blanka Karge, Christoph Wittmann, Mark Broenstrup
  • Method and Measuring Device for Determination of the Growth Rate of Biofilm
    Publication number: 20170350875
    Abstract: A method for determination of the growth rate of biofilm (7) using an electrical impedance analyses is disclosed. The method comprises the steps of: bringing a culture medium fluid (3) in contact to an electrode structure (4a, 4b), having biofilm (7) grown within the fluid culture medium (3) with the biofilm (7) arranged in distance to the electrodes structure (4a, 4b), so that the fluid culture medium (3) is placed between the growing biofilm (7) and the electrode structure (4a, 4b); measuring the impedance of the electrodes structure (4a, 4b) over a monitoring time, and determining the growth rate of the biofilm (7) as a function of the reduction rate of the impedance values measured on the electrode structure (4a, 4b).
