Sulfate-reducing bacteria methylate mercury at variable rates in pure culture and in marine sediments.

Differences in methylmercury (CH(3)Hg) production normalized to the sulfate reduction rate (SRR) in various species of sulfate-reducing bacteria (SRB) were quantified in pure cultures and in marine sediment slurries in order to determine if SRB strains which differ phylogenetically methylate mercury (Hg) at similar rates. Cultures representing five genera of the SRB (Desulfovibrio desulfuricans...

Distribution of methanogenic and sulfate-reducing bacteria in near-shore marine sediments.

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, wit...

Community size and metabolic rates of psychrophilic sulfate-reducing bacteria in Arctic marine sediments.

The numbers of sulfate reducers in two Arctic sediments with in situ temperatures of 2.6 and -1.7 degrees C were determined. Most-probable-number counts were higher at 10 degrees C than at 20 degrees C, indicating the predominance of a psychrophilic community. Mean specific sulfate reduction rates of 19 isolated psychrophiles were compared to corresponding rates of 9 marine, mesophilic sulfate-...

Metabolism of trimethylamine, choline, and glycine betaine by sulfate-reducing and methanogenic bacteria in marine sediments.

The response of methanogenesis and sulfate reduction to trimethylamine, choline, and glycine betaine was examined in surface sediments from the intertidal region of Lowes Cove, Maine. Addition of these substrates markedly stimulated methanogenesis in the presence of active sulfate reduction, whereas addition of other substrates, including glucose, acetate, and glycine, had no effect on methane ...
