AB  - Anaerobic bioreactors are often used for removal of xenobiotic and highly toxic 
      pollutants from wastewater. Most of the time, the pollutant is so toxic that the 
      stability of the reactor becomes compromised. It is well known that methanogens 
      are one of the most sensitive organisms in the anaerobic consortia and hence the 
      stability of the reactors is highly dependant on methanogenesis. Unfortunately 
      few studies have focused on recovering the methanogenic activity once it has been 
      inhibited by highly toxic pollutants. Here we establish a quick recovery strategy 
      for neutralization of an acidified UASB reactor after failure by intoxication 
      with an excess of TCP in the influent. Once the reactor returned to pH values 
      compatible with methanogenesis, biogas production was re-started after one day 
      and the system was re-acclimated to TCP. Successful removal of TCP from synthetic 
      wastewater was shown for concentrations up to 70mg/L after restoration.
