Biofilm formation on microtiter plates. Biofilm production of Prevotella intermedia strains 17 and 17-2 on polystyrene microtiter plates: a representative pair of microtitier plate wells from each experiment stained with 0.1% crystal violet solution after 24 h of incubation (A). The quantitative analysis of biofilm production as measuring the optical density of destained biofilms at 570 nm (B). Bars indicate standard deviations.
