(Submitter supplied) Bioavailability of electron acceptors is probably the most limiting factor in the restoration of anoxic, contaminated environments. The oxidation of contaminants such as aromatic hydrocarbons, particularly in aquifers, often depends on the reduction of ferric iron or sulphate. We have previously detected a highly active fringe zone beneath a toluene plume at a tar-oil contaminated aquifer in Germany, where a specialized community of contaminant degraders co-dominated by Desulfobulbaceae and Geobacteraceae had established. more...

(Submitter supplied) Geobacter metallireducens serves as the model for Geobacter species that anaerobically oxidize aromatic contaminants with the reduction of Fe(III) oxides in contaminated sediments. Analysis of the complete G. metallireducens genome sequence revealed a 307 kb region, designated the aromatics island, not found in closely related species that do not degrade aromatics. This region encoded enzymes for the degradation of benzoate and other aromatic compounds with the exception of the genes for the conversion of toluene to benzyol-CoA which were in a different region of the genome. more...
