Biofilm testing methods

WebThe Single Tube Method (ASTM E2871) is a standard method that measures the efficacy of antimicrobials against biofilm bacteria that has been shown to be reproducible, responsive and rugged. WebMethods of studying biofilm formation include microbiological, physical, chemical, and microscopic methods. The biofilm consists of about 85–96% water, which means that only 2–5% of the total biofilm volume is detectable on dry surfaces.
