Ozonation is often promoted as one of the most effective disinfection procedures. There are numerous reports on how ozone effectively kills bacteria and molds, and disarms viruses within seconds due to its exceptional oxidative activity and small size.
Still, there are examples of thermophilic bacteria existing in volcanoes, as well as viruses in arctic ice, so they both can adapt to extreme conditions. Are there any examples of bacteria, viruses or molds (not necessarily pathogens) that cannot be killed by ozone, or at least show significantly higher resistance to oxidation?
