Rapid Benzene Degradation in Methanogenic Sediments from a Petroleum-Contaminated Aquifer

Received 13 November 1997/Accepted 26 February 1998

In methanogenic sediments from a petroleum-contaminated aquifer, [14C]benzene was converted to 14CH4 and 14CO2 without an apparent lag. Phenol, acetate, and propionate were intermediates in benzene mineralization. These results suggest that alternative electron acceptors need not be available for there to be significant natural attenuation of benzene in some petroleum-contaminated aquifers.
