Microbial metabolism in Reservoir 29, an acid (pH 3) strip mine lake in the Greene-Sullivan State Forest, Indiana, was studied. There were active populations of algae and heterotrophic bacteria in the lake. Algal productivity was relatively low, presumably because of the poor nutritional status of the lake. Bacterial sulfate reduction in the sediments of Reservoir 29 was extensively studied, because this process can neutralize acidity. The reduction of sulfate was biologically mediated, because it had a temperature optimum of 37 C. Hydrogen gas was the only electron donor that stimulated sulfate reduction at pH 3; organic acids.
