About F11 Bacteria

  • F11 bacteria (Labrys portucalensis) are a strain of aerobic bacterium from the Xanthobacteraceae family.
  • These have adapted to survive in harsh, polluted environments by using contaminants as energy sources.
  • These bacteria were originally isolated from contaminated industrial soil in Portugal. 
  • It can break down and transform at least three types of per- and polyfluoroalkyl substances (PFAS), and some of the toxic byproducts, 

What are Forever Chemicals?

  • They are called “forever chemicals” because of their tendency to stick around in the atmosphere, rainwater and soil for long periods of time.
  • They are known to stay in the environment virtually forever and contribute to environmental degradation which adversely impacts the health of all organisms including human beings.
  • PFAs can migrate to the soil, water and air during their production and use.
  • These are listed in the Stockholm Convention.
