De Novo sequences of Haloquadratum walsbyi from Lake Tyrrell, Australia, reveal a aariable genomic landscape [PDF]

Archaea, Volume 2015, Issue 1, 2015., 2015
Hypersaline systems near salt saturation levels represent an extreme environment, in which organisms grow and survive near the limits of life. One of the abundant members of the microbial communities in hypersaline systems is the square archaeon ...

Identification of microorganism belonging to the Halobacteriaceae family in the salt mine of Zipaquirá, Cundinamarca, Colombia

Acta Biológica Colombiana, 2004
This study was designed to identified halophytus microorganisms on samples from the salt mines of Zipaquirá, Colombia. We identified two representative genre Halobacterium sp. and Halococcus sp. which grew at an optimal NaCl concentration of 2.5 M.

A Spotlight on Archaea in Humans, Livestock and Poultry: A Review. [PDF]

Vet Med Sci
The microbiota includes prokaryotes (archaea and bacteria) and eukaryotes. Archaea are single‐celled prokaryotes and essential part of gut microbiome. Researches on archaea in ruminants and humans are more than mono‐gastric. The low abundance of archaea in the gut depends on the method used (metagenomics or meta‐transcriptomic) and age of people or ...

The seminal plasma microbiome of men with testicular germ cell tumours described by small RNA sequencing

Andrology, Volume 11, Issue 4, Page 756-769, May 2023., 2023
Abstract Background It has been estimated that microorganisms are involved in the pathogenesis of approximately 20% of all cancers. Testicular germ cell tumours (TGCTs) are the most common type of malignancy in young men and arise from the precursor cell, germ cell neoplasia in situ (GCNIS).

Adaptive genetic traits in pelagic freshwater microbes

Environmental Microbiology, Volume 25, Issue 3, Page 606-641, March 2023., 2023
Abstract Pelagic microbes have adopted distinct strategies to inhabit the pelagial of lakes and oceans and can be broadly categorized in two groups: free‐living, specialized oligotrophs and patch‐associated generalists or copiotrophs. In this review, we aim to identify genomic traits that enable pelagic freshwater microbes to thrive in their habitat ...

Emended descriptions of genera of the family Halobacteriaceae [PDF]

INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROBIOLOGY, 2009
The family Halobacteriaceae currently contains 96 species whose names have been validly published, classified in 27 genera (as of September 2008). In recent years, many novel species have been added to the established genera but, in many cases, one or more properties of the novel species do not agree with the published descriptions of the genera ...

Experimental evolution of environmental tolerance, acclimation, and physiological plasticity in a randomly fluctuating environment

Evolution Letters, Volume 6, Issue 6, Page 522-536, December 2022., 2022
Abstract Environmental tolerance curves, representing absolute fitness against the environment, are an empirical assessment of the fundamental niche, and emerge from the phenotypic plasticity of underlying phenotypic traits. Dynamic plastic responses of these traits can lead to acclimation effects, whereby recent past environments impact current ...

Pleistocene glacial and interglacial ecosystems inferred from ancient DNA analyses of permafrost sediments from Batagay megaslump, East Siberia

Environmental DNA, Volume 4, Issue 6, Page 1265-1283, November 2022., 2022
As the past is the key to the future, to understand community transformations and ecological interactions, we reconstructed ecosystem‐wide biotic composition (from viruses to megaherbivores) between glacials and interglacials from the Middle and Late Pleistocene at the Batagay megaslump, east Siberia.

Ancient saltern metagenomics: tracking changes in microbes and their viruses from the underground to the surface

Environmental Microbiology, Volume 23, Issue 7, Page 3477-3498, July 2021., 2021
Summary Microbial communities in hypersaline underground waters derive from ancient organisms trapped within the evaporitic salt crystals and are part of the poorly known subterranean biosphere. Here, we characterized the viral and prokaryotic assemblages present in the hypersaline springs that dissolve Triassic‐Keuper evaporite rocks and feed the ...

High-Altitude Open-Pit Coal Mining has Changed the Sulfur Cycle and Ecological Network of Plant Rhizosphere Microorganisms. [PDF]

Ecol Evol
This study explored the changes in functional genes related to sulfur cycling and microbial diversity during different stages of succession following the ecological restoration of a mining site in a cold arid area. A total of three succession stages were selected—natural, secondary, and artificial.
