Fig. 5.

Representative live/dead staining images of biofilms adherent on resin disks. The live bacteria were stained green, and the dead bacteria were stained red. When live and dead bacteria were in close proximity or on the top of each other, the staining had yellow/orange colors. SBMP control was fully covered by primarily live bacteria. In contrast, (B), (C) and (D) showed noticeably less bacterial adhesion, and the biofilms consisted of primarily dead bacteria.
