Abstract: Biofilm forming organisms 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. Biofilm forming organisms 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 antimicrobial reagent may be determined by treating the projections with antimicrobial reagent before carrying out the assay, by treating each row of projections with a different antimicrobial reagent, and each of the projections in a row with a different concentration of antimicrobial reagent.

Abstract: A method for testing the performance of surface coatings on the formation of biofilm and encrustation on materials. The method includes, providing a plurality of material retaining sites, providing the material retaining sites with a material, wherein the material models a surface likely to be involved in biofilm formation and encrustation deposit. The method further includes the steps of providing a liquid growth medium, wherein the liquid growth medium includes at least one microorganism, the liquid growth medium arranged to cover at least a portion of the material, and incubating microorganism and encrustation on the material retaining sites in the presence of the liquid growth medium.

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.
