Biofilms grown for 64.5 h in or mFUM4- (A) or iHS medium(B). FISH staining of a fixed biofilm; the biofilm base in the side views is directed towards the top view. (A) red: F. nucleatum, white: V. dispar, green: non-hybridised cells, DNA staining (YoPro-1 + Sytox), blue: EPS. (B) cyan: streptococci, red: F. nucleatum, green: non-hybridised cells, DNA staining (YoPro-1 + Sytox). Figures show a representative area of one disc. Scale bars: 20 μm.
