The Cr(VI) reduction was investigated in batch reactors using a phenol enriched anaerobic consortium supplemented with a Cr(VI) reducing organism, E.coli ATCC 33456. The effect of concentrations of Cr(VI) and phenol as well as the ratio of phenol-degrading consortium to E.coli was assessed. Simultaneous phenol degradation and Cr(VI) reduction were accomplished under anaerobic conditions in a mixed culture consisting of phenol degraders and Cr(VI) reducers. The correlation between phenol degradation and the microbial composition in the cultures illustrated that Cr(VI) reduction by E.coli depends on metabolites formed from phenol degradation by the anaerobic consortium.
