Cable bacteria associated with long‐distance electron transport in New England salt marsh sediment

摘要: Summary Filamentous Desulfobulbaceae have been proposed as ‘cable bacteria’, which electrically couple sulfide oxidation and oxygen reduction in marine sediment thereby create a centimetre-deep suboxic zone. We incubated New England salt marsh found long-distance electron transport across 6 mm 16S rRNA genes identical to those of previously observed cable bacteria Aarhus Bay incubations. Cable density cores was quantified by fluorescence situ hybridization. In contrast the coastal, subtidal sediments with short-termed blooms based on rapidly depleted iron pools, community ongoing sulfate therefore probably more persistent. Previously seasonal correlation between dominance extensive reduced sulfur marshes suggest that at times may an important role situ.
