The ability of microbial populations to mediate the anaerobic transformation of four aromatic compounds (aniline, benzoic acid, pyridine, and quinoline) in sediments of the Tsengwen River was examined. Along the river, from a freshwater (0.0° salinity) to an oceanic (37.0° salinity) environment, five sampling stations were chosen to collect the sediment. Sediment slurries were incubated in an anaerobic mineral salts medium that was amended with multiple electron acceptors, including manganese (IV) and ferric (III) oxides, and the concentrations of the aromatic substrates were followed over a 3- to 4-month period. Most sediment samples showed a complete loss of benzoic acid and quinoline (0.12-0.21 mM) within approximately three months. Pyridine was transformed after a lag period of 53 days in the sediment slurries from the freshwater environment which had been amended with both metal oxide (either Fe (OH)3 or MnO2) and inhibitor (either BESA or molybdate). Pyridine was not transformed in other sediment slurries. No significant metabolism of aniline was apparent in any of the sediments. |
