AB  - This work reports the first successful application of graphene oxide (GO) and 
      partially reduced GO (rGO) as redox mediator (RM) to increase the 
      biotransformation of the recalcitrant iodinated contrast medium, iopromide (IOP). 
      Results showed that GO-based materials promoted up to 5.5 and 2.8-fold faster 
      biotransformation of IOP by anaerobic sludge under methanogenic and 
      sulfate-reducing conditions, respectively. Correlation between the extent of 
      reduction of GO and its redox-mediating capacity was demonstrated, which was 
      reflected in faster removal and greater extent of biotransformation of IOP. 
      Further analysis indicated that the biotransformation pathway of IOP involved 
      multiple reactions including deiodination, decarboxylation, demethylation, 
      dehydration and N-dealkylation. GO-based materials could be strategically 
      tailored and integrated in biological treatment systems to effectively enhance 
      the redox conversion of recalcitrant pollutants commonly found in wastewater 
      treatment systems and industrial effluents.
