Abstract:
:The distribution of methanogenic and sulfate-reducing bacteria was examined in sediments from three sites off the coast of eastern Connecticut and five sites in Long Island Sound. Both bacterial groups were detected at all sites. Three distributional patterns were observed: (i) four sites exhibited methanogenic and sulfate-reducing populations which were restricted to the upper 10 to 20 cm, with a predominance of sulfate reducers; (ii) three sites in western Long Island Sound exhibited a methanogenic population most abundant in sediments deeper than those occupied by sulfate reducers; (iii) at one site that was influenced by fresh groundwater, methanogens and sulfate reducers were numerous within the same depths; however, the number of sulfate reducers varied vertically and temporally with sulfate concentrations. It was concluded that the distributions of abundant methanogenic and sulfate-reducing bacteria were mutually exclusive. Methanogenic enrichments yielded all genera of methanogens except Methanosarcina, with the methanobacteria predominating.
