Electron microscopy (EM), denaturing gradient gel electrophoresis (DGGE) and 16S rDNA sequencing were used to examine the structure and diversity of microbial mats present in an acid-sulphate-chloride (pH 3.1) thermal (58-62 degrees C) spring in Norris Basin, Yellowstone National Park, WY, USA, exhibiting rapid rates of arsenite oxidation. Initial visual assessments, scanning EM and geochemical measurements revealed the presence of three distinct mat types. Analysis of 16S rDNA fragments with…

High abundance of heterotrophic prokaryotes in hydrothermal springs of the Azores as revealed by a network of 16S rRNA gene-based methods

Different methods to analyse prokaryotic communities in complex ecosystems can complement each other to obtain an in-depth picture of the taxonomic composition and diversity within these hydrothermal springs.

Archaeal and bacterial communities in geochemically diverse hot springs of Yellowstone National Park, USA

Energy-yields for a number of chemolithoautotrophic reactions are provided for >80 sampling sites in Yellowstone, showing that the knallgas reaction is just one of many exergonic reactions in the Yellowstone hot springs, that energy-y yields for certain reactions can vary substantially from one site to the next, and that few of the demonstrated exergonics reactions are known to support microbial metabolism.

Functional genes and thermophilic microorganisms responsible for arsenite oxidation from the shallow sediment of an untraversed hot spring outlet

Microcosm assay indicated that the microbial community from the hot spring was able to efficiently oxidize As(III) using glucose, lactic acid, yeast extract or sodium bicarbonate as the sole carbon source, and twenty one novel arsenite oxidase genes were identified from the samples, which highlight the high diversity of the arsenite-oxidizing microorganisms from thehot spring.

Linking microbial oxidation of arsenic with detection and phylogenetic analysis of arsenite oxidase genes in diverse geothermal environments.

The aroA sequences identified in the current study expand the phylogenetic distribution of known Mo-pterin arsenite oxidase genes, and suggest the importance of three prominent genera of the order Aquificales in arsenite oxidation across geochemically distinct geothermal habitats ranging in pH from 2.6 to 8.

Archaeal Community Revealed by 16s rRNA and Fluorescence in situ Hybridization in a Sulphuric Hydrothermal Hot Spring, Northern Taiwan

The archaeal community composition of Yangmingshan National Park in northern Taiwan was investigated by 16S rRNA and fluorescence in situ hybridization (FISH), and AciI, BstUI and RsaI were shown to be the optimal TREs for TRE-RFLP.

Isolation and Distribution of a Novel Iron-Oxidizing Crenarchaeon from Acidic Geothermal Springs in Yellowstone National Park

The broad distribution of highly related MK1-like 16S rRNA gene sequences in acidic Fe(III) oxide microbial mats is consistent with the observed characteristics and growth optima of Metallosphaera-like strain MK1 and emphasizes the importance of this newly described taxon in Fe(II) chemolithotrophy in acidic high-temperature environments of YNP.

Effects of Abiotic Factors on the Phylogenetic Diversity of Bacterial Communities in Acidic Thermal Springs

A carefully designed comparative analysis of acidic thermal springs in Yellowstone National Park was used to determine how abiotic factors (chemistry and temperature) shape acidophile microbial communities.

Archaeal and bacterial diversity in acidic to circumneutral hot springs in the Philippines.

Based on the phylogenetic inference, sulfur metabolisms appear to be key physiological functions in these hot springs and their relationships with geochemical conditions improve the understanding of microbial diversity and community composition in acidic to circumneutral terrestrial hot springs.

Microbial Diversity and Biochemical Potential Encoded by Thermal Spring Metagenomes Derived from the Kamchatka Peninsula

Assessing and exploiting the prokaryotic diversity of two microbial communities derived from different Kamchatkian thermal springs by metagenomic approaches found three novel genes conferring lipolytic and proteolytic activity were identified.

Metagenome Sequence Analysis of Filamentous Microbial Communities Obtained from Geochemically Distinct Geothermal Channels Reveals Specialization of Three Aquificales Lineages

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.



Novel Bacterial and Archaeal Lineages from an In Situ Growth Chamber Deployed at a Mid-Atlantic Ridge Hydrothermal Vent

The phylogenetic diversity was determined for a microbial community obtained from an in situ growth chamber placed on a deep-sea hydrothermal vent on the Mid-Atlantic Ridge and the prevalence of clones related to thermophilic microbes that use hydrogen as an electron donor and sulfur compounds indicates the importance of hydrogen oxidation and sulfur metabolism at deep- sea hydroThermal vents.

A molecular view of archaeal diversity in marine and terrestrial hot water environments

A molecular phylogenetic survey of naturally occurring archaeal diversities in hot water environments was carried out by using the PCR-mediated small subunit rRNA gene (SSU rDNA) sequencing, which revealed the distant relationship not only to the rDNA sequences of the cultivated thermophilic archaea, but also to the sequences of unidentifiedarchaeal rDNA clones found in other hotWater environments.

Small-subunit ribosomal DNA diversity was found to be very high in a Hawaiian soil community that might be expected to have lower diversity than the communities in continental soils because the Hawaiian soil is geographically isolated, is subjected to a constant climate, and harbors low plant diversity.
