Archaea of the Miscellaneous Crenarchaeotal Group are abundant, diverse and widespread in marine sediments [PDF]

ISME Journal, 2012
Abstract 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 slot blot hybridization, quantitative PCR (qPCR) and catalyzed reporter deposition FISH) using newly developed probes and primers for

Anaerobic oxidation of ethane by archaea from a marine hydrocarbon seep

Nature, 2019
Ethane is the second most abundant component of natural gas in addition to methane, and-similar to methane-is chemically unreactive. The biological consumption of ethane under anoxic conditions was suggested by geochemical profiles at marine hydrocarbon seeps1-3, and through ethane-dependent sulfate reduction in slurries4-7.

Expansion of the Marine Archaea

Science, 2001
One group of the Archaea (ancient bacteria) began life inhabiting the hyperthermal vents of the oceans but then suddenly expanded to more temperate ocean niches during the Cretaceous. In a Perspective, [Smith][1] discusses new work ([ Kuypers et al .][2]) pinpointing the exact time of this archaeal expansion within the mid-Cretaceous, and the changing ...

Diversity and mode of transmission of ammonia‐oxidizing archaea in marine sponges

Environmental Microbiology, 2008
Summary The model marine crenarchaeote ‘ Cenarchaeum symbiosum ’ is until now the only ammonia‐oxidizing archaeon known from a marine sponge. Here, phylogenetic analyses based on the 16S rRNA and ammonia monooxygenase subunit A ( amoA )

The Role of Marine Anaerobic Bacteria and Archaea in Bioenergy Production

2013
The development of products from marine bioresources is gaining importance in the biotechnology sector. The global market for Marine Biotechnology products and processes was, in 2010, estimated at 2.8 billion with a cumulative annual growth rate of 510% (Børresen et al., Marine biotechnology: a new vision and strategy for Europe.

Significant contribution of Archaea to extant biomass in marine subsurface sediments

Nature, 2008
Deep drilling into the marine sea floor has uncovered a vast sedimentary ecosystem of microbial cells. Extrapolation of direct counts of stained microbial cells to the total volume of habitable marine subsurface sediments suggests that between 56 Pg (ref. 1) and 303 Pg (ref. 3) of cellular carbon could be stored in this largely unexplored habitat. From

Marine Bacteria and Archaea: Diversity, Adaptations, and Culturability

2016
With an estimated total number of 6.6 × 1029 cells, Bacteria and Archaea in marine waters and sediments constitute a major fraction of global microbial biomass. Most marine bacterial communities are highly diverse and individual samples can comprise over 20,000 species.

Proteorhodopsin lateral gene transfer between marine planktonic Bacteria and Archaea

Nature, 2006
Planktonic Bacteria, Archaea and Eukarya reside and compete in the ocean's photic zone under the pervasive influence of light. Bacteria in this environment were recently shown to contain photoproteins called proteorhodopsins, thought to contribute to cellular energy metabolism by catalysing light-driven proton translocation across the cell membrane. So
