Summary
Phenolic pollutants were toxic to the bioactivity of anaerobic benzoate-degrading granules. Cresols were more toxic than phenol, which in turn was more toxic than dihydroxybenzenes. The toxicity was dependent on the hydrophobicity of the functional group, but not their positions. The granules exhibited mild resistance to the toxicity of phenolic pollutants, probably because of their layered microstructure.
