Detection of anaerobic sulfate-reducing bacteria in oxygen-containing upper water layers of the Black and Baltic Seas

Detection of anaerobic sulfate-reducing bacteria in oxygen-containing upper water layers of the... Fluorescent in situ hybridization (FISH) and PCR were used for analysis of phylogenetic structure of anaerobic sulfate-reducing bacterial communities in oxygen-containing upper water layers of meromictic basins: the Black Sea and the Gdansk Deep of the Baltic Sea. In the Black Sea (continental slope at depths 30–70 m), cells of sulfate-reducing bacteria (SRB) hybridizing with 16S rRNA-specific FISH-probes for Desulfotomaculum, Desulfobacter, and Desulfovibrio genera were revealed, whereas Desulfomicrobium-related bacteria were prevalent in the chemocline zone at a 150-m depth.

Abstract

Fluorescent in situ hybridization (FISH) and PCR were used for analysis of phylogenetic structure of anaerobic sulfate-reducing bacterial communities in oxygen-containing upper water layers of meromictic basins: the Black Sea and the Gdansk Deep of the Baltic Sea. In the Black Sea (continental slope at depths 30–70 m), cells of sulfate-reducing bacteria (SRB) hybridizing with 16S rRNA-specific FISH-probes for Desulfotomaculum, Desulfobacter, and Desulfovibrio genera were revealed, whereas Desulfomicrobium-related bacteria were prevalent in the chemocline zone at a 150-m depth. Besides Desulfotomaculum (SRB subgroup 1), Desulfobacter (SRB subgroup 4), and Desulfovibrio-Desulfomicrobium (SRB subgroup 6), nested PCR with the use of 16S rRNA gene-specific primers detected the presence of Desulfococcus–Desulfonema–Desulfosarcina (SRB subgroup 5) in the oxygen-containing water column of the Black and Baltic seas. Active enrichment SRB culture that contained bacterium Desulfosporosinus sp. as a major component was obtained from the Black Sea water sample collected at a 70-m depth.
