So how do traditional disinfectants stack up against Biofilm? We have video and study that shows you who wins.
The following video clip is a computer model time-lapse simulation of a developing biofilm made by the Montana State University, The Center for Biofilm Engineering. At the 100-hour time point, the biofilm is placed in continuous contact with a disinfectant for 15 hours. This was more than enough time for a disinfectant to kill any bacterial life. As the animation continues,'persister cells' (low metabolic rate cells protected deep within the biofilm) are seen to have a profound influence promoting the survival of the biofilm. This film demonstates the remarkable resistance of microbial biofilms to disinfectants and other chemical agents, including most antibiotics.
