First archaeal rDNA sequences from Argentine coastal waters: Unexpected PCR characterization using eukaryotic primers

open access: yesCiencias Marinas, 2012
Many members of Archaea, a group of prokaryotes recognized three decades ago, colonize extreme environments; however, new research has shown that Archaeans are also abundant components of plankton in the open sea, where they play a key role in the ...

PCR biases distort bacterial and archaeal community structure in pyrosequencing datasets [PDF]

open access: yes, 2012
As 16S rRNA gene targeted massively parallel sequencing has become a common tool for microbial diversity investigations, numerous advances have been made to minimize the influence of sequencing and chimeric PCR artifacts through rigorous quality control ...

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

open access: yesAnimal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

Proteomic Analysis of Methanonatronarchaeum thermophilum AMET1, a Representative of a Putative New Class of Euryarchaeota, “Methanonatronarchaeia” [PDF]

open access: yesGenes, 2018
The recently discovered Methanonatronarchaeia are extremely halophilic and moderately thermophilic methyl-reducing methanogens representing a novel class-level lineage in the phylum Euryarchaeota related to the class Halobacteria. Here we present a detailed analysis of 1D-nano liquid chromatography–electrospray ionization tandem mass spectrometry data ...

Occurrence and expression of novel methyl-coenzyme M reductase gene (mcrA) variants in hot spring sediments

open access: yesScientific Reports, 2017
Recent discoveries have shown that the marker gene for anaerobic methane cycling (mcrA) is more widespread in the Archaea than previously thought.

Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

Are Marine Group II Euryarchaeota significant contributors to tetraether lipids in the ocean? [PDF]

open access: yesProceedings of the National Academy of Sciences, 2014
Lincoln et al. (1) claim that Marine Group II Euryarchaeota (MG-II) are significant contributors to glycerol dibiphytanyl glycerol tetraether (GDGT) lipids in the ocean and biosynthesize crenarchaeol, a membrane lipid generally attributed to Thaumarchaeota (MG-I). The authors present two lines of convergent evidence for their far-reaching claim.

The Distribution of Bathyarchaeota in Surface Sediments of the Pearl River Estuary Along Salinity Gradient

open access: yesFrontiers in Microbiology, 2020
Bathyarchaeota, a recently proposed archaeal phylum, is globally distributed and highly abundant in anoxic sediments. Metabolic pathways of the Bathyarchaeota members are diverse and, hence, this phylum has been proposed to play an important role in ...
