ABSTRACT:
This invention provides a methodology for controlled biofilm formation in accordance with a monitored protocol. In a typical embodiment, a natural biofilm inoculum is used to form a simulated natural biofilm on retrievable slides in an annular reactor. The monitored protocol in the annular reactor subjects the bacterial consortia of the simulated natural biofilm to simulated environmental conditions. The invention simulated natural biofilm on a slide surface has utility for the testing of formulated product activity for inhibition or removal of the simulated natural biofilm, thereby providing a reliable indicator of the relative activity of the products under natural environmental conditions.
