Late Proterozoic rise in atmospheric oxygen concentration inferred from phylogenetic and sulphur-isotope studies
The evolution of non-photosynthetic sulphide-oxidizing bacteria was contemporaneous with a large shift in the isotopic composition of biogenic sedimentary sulphides between 0.64 and 1.05 billionExpand

Heterotrophic Archaea dominate sedimentary subsurface ecosystems off Peru.
Studies of deeply buried, sedimentary microbial communities and associated biogeochemical processes during Ocean Drilling Program Leg 201 showed elevated prokaryotic cell numbers in sediment layersExpand

Dense populations of a giant sulfur bacterium in Namibian shelf sediments.
A previously unknown giant sulfur bacterium is abundant in sediments underlying the oxygen minimum zone of the Benguela Current upwelling system. The bacterium has a spherical cell that exceeds by upExpand

Uncultured archaea in deep marine subsurface sediments: have we caught them all?
Deep marine subsurface sediments represent a novel archaeal biosphere with unknown physiology; the sedimentary subsurface harbors numerous novel phylogenetic lineages of archaea that are at presentExpand

Archaea of the Miscellaneous Crenarchaeotal Group are abundant, diverse and widespread in marine sediments
Members of the highly diverse Miscellaneous Crenarchaeotal Group (MCG) are globally distributed in various marine and continental habitats. In this study, we applied a polyphasic approach (rRNA slotExpand

Stratified Communities of Active Archaea in Deep Marine Subsurface Sediments
ABSTRACT Archaeal 16S rRNA was extracted from samples of deep marine subsurface sediments from Peru Margin site 1227, Ocean Drilling Program leg 201. The amounts of archaeal 16S rRNA in each extractExpand

Hydrocarbon-degrading bacteria enriched by the Deepwater Horizon oil spill identified by cultivation and DNA-SIP
The massive influx of crude oil into the Gulf of Mexico during the Deepwater Horizon (DWH) disaster triggered dramatic microbial community shifts in surface oil slick and deep plume waters. PreviousExpand

Thermophilic anaerobic oxidation of methane by marine microbial consortia
The anaerobic oxidation of methane (AOM) with sulfate controls the emission of the greenhouse gas methane from the ocean floor. AOM is performed by microbial consortia of archaea (ANME) associatedExpand

Distributions of Microbial Activities in Deep Subseafloor Sediments
Diverse microbial communities and numerous energy-yielding activities occur in deeply buried sediments of the eastern Pacific Ocean. Distributions of metabolic activities often deviate from theExpand
