ABSTRACT The hydrothermal fluid chemistry at El Tatio Geyser Field (ETGF) in northern Chile suggests that biogenic CO2–CH4 cycling may play an important role in water chemistry, and relatively low sulfate (0.6–1 mM) and high molecular hydrogen (H2) concentrations (67–363 nM) suggest that methanogenic Archaea are present in ETGF microbial mats. In this study, δ13C analysis of dissolved inorganic carbon and methane was not indicative of biogenic methane production (δ13CCH4 values ranging from −15… Expand
Two Archaeal Metagenome-Assembled Genomes from El Tatio Provide New Insights into the Crenarchaeota Phylum
A phylogenomic and functional analysis of the first two Crenarchaeota MAGs belonging to El Tatio geysers fields in Chile showed that both MAG 9-5TAT and MAG 47- 5TAT likely represent new species in the genus Thermoproteus and the genus Sulfolobus, respectively. Expand
Composition and predicted functions of the bacterial community in spouting pool sediments from the El Tatio Geyser field in Chile
The composition and predicted functions of the bacterial community in spouting pool sediments from the ETGF as revealed by high-throughput sequencing of 16S rRNA genes showed that while there were differences in richness and diversity between samples, bacterial communities were primarily dominated by the phyla Proteobacteria.

Living at the Frontiers of Life: Extremophiles in Chile and Their Potential for Bioremediation
Interestingly, the remarkable adaptative capabilities of extremophiles convert them into an attractive source of catalysts for bioremediation and industrial processes. Expand
Dissimilatory arsenate-respiring prokaryotes catalyze the dissolution, reduction and release of arsenic from paddy soils into groundwater: implication for the effect of sulfate
A diversity of DARPs in the paddy soils significantly catalyzed the dissolution, reduction and release of arsenic and iron from insoluble phase into solution, and the presence of sulfate significantly increased the microbial reactions. Expand
Biohythane production from organic waste: Recent advancements, technical bottlenecks and prospects
Abstract The availability of fossil fuels is a major factor that determines the economy of a country. However, possible exhaustion of fossil fuel deposits as well as increased pollution, and otherExpand
Evaporative silicification in floating microbial mats: patterns of oxygen production and preservation potential in silica-undersaturated streams, El Tatio, Chile.
Patterns of silica precipitation in El Tatio microbial communities show that the preservation potential of silicifying mats in the rock record is strongly dependent on aqueous silica concentrations, likely forming a modest feedback loop between diminished photosynthesis and crust precipitation.

Methanothermus fervidus, sp. nov., a novel extremely thermophilic methanogen isolated from an Icelandic hot spring
A rod-shaped extremely thermophilic methanogen is described, growing between 65 and 97 °C with an optimal temperature around 83 °C and a doubling time of 170 min, indicating that the isolate belongs to a new family, the Methanothermaceae, within the order Methanobacteriales. Expand

Algal-bacterial mats which grow in the effluent channels of alkaline hot springs provided an environment suitable for studying natural thermophilic methane producing bacteria and methanogenic bacteria were present over a range of 68 to 30 degrees C, with optimum methanogenesis near 45 degrees C.

Occurrence, diversity, and abundance of methanogenic archaea in terrestrial hot springs of Kamchatka and Saõ Miguel Island
High diversity of the thermophilic methanogens inhabiting terrestrial hot springs and the presence among them of new groups with yet unknown substrate specificity are indicated. Expand
Geochemistry and microbial ecology in alkaline hot springs of Ambitle Island, Papua New Guinea
When compared to other alkaline, island-based, high-arsenic, or shallow-sea hydrothermal communities, the Ambitle Island archaeal communities are unique in geochemical conditions, and in taxonomic diversity, richness, and evenness. Expand
Microbiology of Methanogenesis in Thermal, Volcanic Environments
Microbial methanogenesis was examined in thermal waters, muds, and decomposing algal-bacterial mats associated with volcanic activity in Yellowstone National Park and revealed that the microbial population was predominantly rod shaped and asporogenous. Expand
Arsenite oxidase gene diversity among Chloroflexi and Proteobacteria from El Tatio Geyser Field, Chile.
This research expands the known distribution and diversity of arsenite oxidation in natural geothermal settings, and provides information about the evolutionary history of microbe-arsenic interactions. Expand
Metabolic, Phylogenetic, and Ecological Diversity of the Methanogenic Archaea
The ecology of methanogens highlights their complex interactions with other anaerobes and the physical and chemical factors controlling their function. Expand
Methane metabolism in the archaeal phylum Bathyarchaeota revealed by genome-centric metagenomics
These findings indicate that methane metabolism arose before the last common ancestor of the Euryarchaeota and BathyarchAEota, and suggest that unrecognized archaeal lineages may also contribute to global methane cycling. Expand
High 16S rDNA bacterial diversity in glacial meltwater lake sediment, Bratina Island, Antarctica
The microbial diversity in maritime meltwater pond sediments from Bratina Island, Ross Sea, Antarctica was investigated by 16S rDNA-dependent molecular phylogeny and revealed the presence of a highly diverse bacterial population and a significantly depth-related composition. Expand
Vertical distribution of methane metabolism in microbial mats of the Great Sippewissett Salt Marsh.
The results suggest that both non-equilibrium H(2) dynamics and the use of non-competitive substrates permit coexistence of methanogens and sulfate-reducing organisms in the mat system. Expand
