Surfacine

Surface Bioactivity

Surfacine kills microorganisms on contact - but is non-toxic to mammalian cells.

In laboratory testing, Surfacine treated surfaces effectively eliminated all human pathogens tested - including bacteria, yeasts and fungi. Typical testing protocol involves bacterial challenges of 10^6 CFU/mL (colony forming units per milliliter of saline) inoculation on treated and untreated control surfaces. After 20 hours in 25C humidity chamber, the surfaces were swabbed and the live bacteria were counted using the conventional plate counting method. Control surfaces show bacteria counts of 10^4 to 10^6 CFU/mL while Surfacine treated surfaces show no measurable level of living microorganisms. We utilized contract laboratories to perform mold and virus testing according to standard protocols. To date, Surfacine proved efficacious against all pathogens tested in this method. The following table lists all the pathogens tested to date, their ATCC strain number, type of organism, and the type of efficacy tested:
