Benzene was mineralized to CO[sub 2] by aquifer-derived microorganisms under strictly anaerobic conditions. The degradation occurred in microcosms containing gasoline-contaminated subsurface sediment from Seal Beach, California, and anaerobic, sulfide-reduced defined mineral medium supplemented with 20 mM sulfate. Benzene, at initial concentrations ranging from 40 to 200 [mu]M, was depleted in all microcosms and more than 90% of [sup 14]C-labeled benzene was mineralized to [sup 14]CO[sub 2].
