Description:
The microflora of a shallow anoxic aquifer underlying a municipal landfill In Oklahoma was characterized by direct light microscopy, most probable number of determinations of sulfate reducers and methanogens, and measurements of methanogenesis in aquifer samples containing either endogenous or exogenous electron donors and various sulfate concentrations. Acridine orange direct counts of bacteria did not vary significantly with time or between 2 major sampling areas. A mapping of sulfate and methane levels indicated that site A is relatively localized. These results suggest that the predominant flow of carbon and energy is through methanogenesis at aquifer site B whereas sulfate reduction predominated at site A. However, both methanogens and sulfate reducers could be isolated from either site. (Copyright (c) Springer-Verlag New York Inc. 1987.)
