A marine microbial consortium apparently mediating anaerobic oxidation of methane
A large fraction of globally produced methane is converted to CO2 by anaerobic oxidation in marine sediments. Strong geochemical evidence for net methane consumption in anoxic sediments is based onExpand
Anaerobic ammonium oxidation by anammox bacteria in the Black Sea
TLDR
Evidence for bacteria that anaerobically oxidize ammonium with nitrite to N2 in the world's largest anoxic basin, the Black Sea is provided and anammox bacteria have been identified and directly linked to the removal of fixed inorganic nitrogen in the environment. Expand
Microbial Reefs in the Black Sea Fueled by Anaerobic Oxidation of Methane
TLDR
Obviously, anaerobic microbial consortia can generate both carbonate precipitation and substantial biomass accumulation, which has implications for the understanding of carbon cycling during earlier periods of Earth's history. Expand
Biogeographical distribution and diversity of microbes in methane hydrate-bearing deep marine sediments on the Pacific Ocean Margin.
TLDR
Results from cluster and principal component analyses, which include previously reported data from the West and East Pacific Margins, suggest that, for these locations in the Pacific Ocean, prokaryotic communities from methane hydrate-bearing sediment cores are distinct from those in Hydrate-free cores.

Measurement of bacterial sulfate reduction in sediments: Evaluation of a single-step chromium reduction method
A procedure which includes the Total Reduced Inorganic Sulfur (TRIS) in a single distillation step is described for the radiotracer measurement of sulfate reduction in sediments. The TRIS includesExpand
Coral mucus functions as an energy carrier and particle trap in the reef ecosystem
TLDR
Coral mucus provides light energy harvested by the zooxanthellae and trapped particles to the heterotrophic reef community, thereby establishing a recycling loop that supports benthic life, while reducing loss of energy and nutrients from the reef ecosystem. Expand
Microenvironment and photosynthesis of zooxanthellae in scleractinian corals studied with microsensors for O2, pH and light
During experimental light-dark cycles, O9 in the tissue of the colonial scleractinian corals Favia sp. and Acropora sp reached >250 % of air saturation after a few minutes in light. Immediately afterExpand
Dense populations of a giant sulfur bacterium in Namibian shelf sediments.
TLDR
A previously unknown giant sulfur bacterium is abundant in sediments underlying the oxygen minimum zone of the Benguela Current upwelling system, and is closely related to the marine filamentous sulfur bacteria Thioploca, abundant in the up welling area off Chile and Peru. Expand
Mineralization of organic matter in the sea bed—the role of sulphate reduction
The bacterial reduction of sulphate to sulphide at the sea bed is a key process in the oceanic sulphur cycle, and is responsible for the oxidation of organic matter which becomes buried below theExpand
