Motile bacteria swimming inside hollow voids.
A. 2D-confocal representation of hollow voids of a 72 h-old 2.67 mM As(III)-exposed biofilm structure containing swimming bacteria. Cells were stained with SYTO9. Scale bar: 20 µm. B. 2D-time progression, in red, from point 1 to point 2 of the cell circled on panel (A). The representation is a projection of 16 confocal images taken at 1.63 second intervals.
