    Microbial communities associated with wet flue gas

    Flue gas desulfurization (FGD) systems are employed to remove SO x gasses that are produced by the combustion of coal for electric power generation, and consequently limit acid rain associated with these activities. Wet FGDs represent a physicochemically extreme environment due to the high operating temperatures and total dissolved solids (TDS) of fluids in the interior of the FGD units.
