Reduction of phenol to benzoate : an electron sink reaction used by a highly enriched anaerobic culture

• A non-methanogenic pasteurised enrichment culture fermenting phenolto benzoate, butyrate and acetate was studied, focusing on the effects of adding yeast extract (0.1, 0.2 or I g!l) or glucose (1.5 mM) together with the phenol (5 mM). The results showed that the reductive formation of benzoate from phenol increased when either yeast extract (1 g 1-') or glucose was added to the medium. The culture also transformed phenol at a higher rate when glucose was added as a "co-substrate" than when it was grown on phenol alone. Furthermore, higher growth rates occurred in cultures grown on both substrates rather than on glucose or phenol alone.
