Summary
4000 mg/l of N−NH4 + and 12 mg/l or Cr+3 caused a 50% reduction in aceticlastic methanogenic activity of an anaerobic sludge.Methanosarcina-like andMethanothrix-like cells were differently affected by the toxicants. The inhibition caused by Cr+3 was reverted by its removal, by addition of iron and by increasing the biomass.
