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.

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

Massive Expansion of Marine Archaea During a Mid-Cretaceous Oceanic Anoxic Event

Science, 2001
Biogeochemical and stable carbon isotopic analysis of black-shale sequences deposited during an Albian oceanic anoxic event (∼112 million years ago) indicate that up to 80 weight percent of sedimentary organic carbon is derived from marine, nonthermophilic archaea.

Ammonia-Oxidizing Archaea in Marine Cold-Water Sponges

2011
Thaumarchaea (Archaea) kommen in vielen terrestrischen und marinen Lebensräumen vor und sind oftmals mit marinen Schwämmen assoziiert. Basierend auf Metagenom- und Kultivierungsstudien hat sich gezeigt, dass viele (wenn nicht sogar alle) Thaumarchaea die Fähigkeit besitzen, mittels dem Enzym Ammoniummonooxygenase (AMO), Ammonium zu oxidieren. In dieser
