The sensitivity of a methanogen and sulfate-reducing bacterium isolated from a sea-based landfill site to Cd^<2+> and Cu^<2+> was studied. Methanogens and sulfate-reducing bacteria in leachates of the waste disposal site were enumerated using the MPN method. Methanobacterium thermoautotrophicum KHT-2, isolated from the leachate, could not grow at 0.5 mM Cd^<2+> or 1.0 mM Cu^<2+> Desulfotomaculum sp. RHT-3, isolated from the same leachate, was able to isolubilize 3.0 mM Cd^<2+> or 2.0 mM Cu^<2+> by production of hydrogen sulfide. When strains KHT-2 and RHT-3 were cultured together in the presence of the heavy metals, strain KHT-2 could grow at high heavy metal concentrations after insolubilization of the metals by strain RHT-3.
