The microbial diversity associated with actively venting deep-sea hydrothermal deposits is tightly connected to the geochemistry of the hydrothermal fluids. Although the dominant members of these deposits drive the structure of the microbial communities, it is less well understood whether the lower abundance groups are as closely connected to the geochemical milieu, or driven perhaps by biotic factors such as microbial community interactions. We used the natural geochemical gradients that exist… Expand
Transient Changes in Bacterioplankton Communities Induced by the Submarine Volcanic Eruption of El Hierro (Canary Islands)
TLDR
Both cytometric and sequence analyses showed that once the eruption ceased, evidences of the volcano-induced changes were no longer observed, and no dramatic changes in community composition were observed. Expand
Diversity patterns of marine heterotrophic culturable bacteria along vertical and latitudinal gradients
TLDR
This isolates collection provides an overview of the distribution patterns of cosmopolitan marine culturable heterotrophic bacteria. Expand
Microbially Mediated Hydrogen Cycling in Deep-Sea Hydrothermal Vents
TLDR
The advent of new techniques for the identification of novel hydrogen-uptake and -evolving enzymes from hydrothermal vent microorganisms from hydrogen-oxidizing microorganisms are discussed. Expand
Diversity and distribution of marine heterotrophic bacteria from a large culture collection
TLDR
A marine culture collection of heterotrophic bacteria (MARINHET) using a standard marine medium comprising a total of 1561 bacterial strains, and covering a variety of oceanographic regions from different seasons and years, from 2009 to 2015 is created. Expand
Metaproteogenomic Profiling of Microbial Communities Colonizing Actively Venting Hydrothermal Chimneys
TLDR
Community proteogenomics was used to investigate and compare the composition, metabolic potential and relative in situ protein abundance of microbial communities colonizing two actively venting hydrothermal chimneys from the Manus Basin back-arc spreading center (Papua New Guinea). Expand
Persephonella atlantica sp. nov.: How to adapt to physico-chemical gradients in high temperature hydrothermal habitats.
TLDR
Experimental results are consistent with the distribution of these catabolic substrates along the temperature gradient observed in active hydrothermal systems and strongly suggest that this adaptive strategy could confer a selective advantage for strain MO1340T in the dynamic part of the ecosystem where hot, reduced Hydrothermal fluid mixes with cold, oxygenated seawater. Expand
Diversity of free-living prokaryotes on terrestrial and marine Antarctic habitats
TLDR
A unique microbial community structure according to each habitat, including specific taxa composing each microbiome was showed, which suggests long-distance dispersal processes occurring from the Peninsula to the Continent. Expand

Low Temperature Geomicrobiology Follows Host Rock Composition Along a Geochemical Gradient in Lau Basin
TLDR
This is the first study of microbial populations on basaltic andesite, which was sampled at Mariner vent field, and reveals the presence of a clade of uncultured Bacteroidetes exclusive to sulfidic environments, and a high degree of heterogeneity in bacterial community composition from one sulfide structure to another. Expand
Inter-field variability in the microbial communities of hydrothermal vent deposits from a back-arc basin.
TLDR
Results show that microbial communities associated with hydrothermal vent deposits in back-arc basins are taxonomically similar to those from mid-ocean ridge systems, but differences in geologic processes between vent fields in aBack-arc basin can influence microbial community structure. Expand
Expanding the distribution of the Aquificales to the deep-sea vents on Mid-Atlantic Ridge and Central Indian Ridge
TLDR
It is demonstrated that this novel lineage in the Aquificales occurs at deep-sea vents in the Mid-Atlantic and Indian Oceans, and together with other deep-SEA isolates, forms a distinct lineage from the terrestrial isolates and sequences. Expand
Temporal and spatial archaeal colonization of hydrothermal vent deposits.
TLDR
A temporal transition in the primary carbon sources used by the archaeal communities is suggested, with potential CO(2)/H(2) methanogens prevalent in BM4 being replaced by possible methylotroph or acetoclastic methanogen and heterotrophs in BM72. Expand
Distribution, Abundance, and Diversity Patterns of the Thermoacidophilic “Deep-Sea Hydrothermal Vent Euryarchaeota 2”
TLDR
Results of quantitative polymerase chain reaction assays with primers specific for the DHVE2 and Archaea demonstrate the ubiquity of theDHVE2 at deep-sea vents and suggest that they are significant members of the archaeal communities of established vent deposit communities. Expand

TLDR
Multiple-pathway and protein-specific functional analysis of metagenome sequence data corroborated results from phylogenetic analyses and clearly demonstrate major differences in metabolic potential across sites. Expand
Metagenome Sequence Analysis of Filamentous Microbial Communities Obtained from Geochemically Distinct Geothermal Channels Reveals Specialization of Three Aquificales Lineages
TLDR
The distribution of Aquificales populations and differences among functional genes involved in energy generation and electron transport is consistent with the hypothesis that geochemical parameters have resulted in niche specialization among members of the Aquificalses. Expand
