    Abstract: The present invention relates to an apparatus and methods for testing the formation of biofilms on various materials. The apparatus includes a lid and a vessel, wherein the lid may be configured to accept various materials for the testing of biofilm formation. For example, the lid may contain a plurality of projections onto which materials may be coated or disposed. The vessel is adapted to receive the lid in a fluid tight communication and to retain a liquid growth medium therein. After a material has been disposed upon the projections, the material is suspended within the vessel containing the liquid growth medium. The material is allowed to incubate for a period of time in which a biofilm forms upon the material. The material is then removed from the liquid growth medium and the biofilms formed thereupon are used to test the efficiency of various biocides.

    Abstract: Bacteria are incubated to form a biofilm on projections by providing a flow of liquid growth medium across projections, the direction of the flow of liquid being repeatedly changed, and an assay made of the resulting biofilm. Bacteria are incubated to form a biofilm on projections arranged in rows, with several projections in each row, while providing a flow of liquid growth medium across each row of projections, and an assay made of the resulting biofilm. Sensitivity of the biofilm to antibacterial reagent may be determined by treating the projections with antibacterial reagent before carrying out the assay, by treating each row of projections with a different antibacterial reagent, and each of the projections in a row with a different concentration of antibacterial reagent. A biofilm assay device includes a vessel including at least one channel for flow of liquid growth medium, projections arranged in at least one row and having a support for supporting the projections within the channel, and a tilt table to flow liquid growth medium along each channel in different directions across the projections. A further biofilm assay device includes a vessel including channels for flow of liquid growth medium, projections arranged in rows and having a support for supporting the projections within the channels, and a rocking table to rock the vessel and flow liquid growth medium along each channel across the projections.
