Test procedure:
Two 250 ml ml glass bottles each containing 50 50 ml ml of tap water were inoculated with a a a a a a a biofilm suspension from a a a a a a a tap Immediately after inoculation a a a a a a a piece o of wire mesh (approx 10 cm2) was inserted into one bottle At the times indicated below samples of 0 0 1 1 and and 1 1 0 0 ml were taken simultaneously from both preparations and and the respective colony counts were determined by plate casting The experiment was performed at at room temperature colony counts were determined with HE agar incubation 48 h at at 36°C Results with new wire mesh Sample
