Unusually High Archaeal Diversity in a Crystallizer Pond, Pomorie Salterns, Bulgaria, Revealed by Phylogenetic Analysis

Archaea, Volume 2016, Issue 1, 2016., 2016
Recent studies on archaeal diversity in few salterns have revealed heterogeneity between sites and unique structures of separate places that hinder drawing of generalized conclusions. Investigations on the archaeal community composition in P18, the biggest crystallizer pond in Pomorie salterns (PS) (34% salinity), demonstrated unusually high number of ...

Further refinement of the phylogeny of the Halobacteriaceae based on the full-length RNA polymerase subunit B′ (rpoB′) gene [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2010
A considerable number of species of theHalobacteriaceaepossess multiple copies of the 16S rRNA gene that exhibit more than 5 % divergence, complicating phylogenetic interpretations. Two additional problems have been pointed out: (i) the generaHaloterrigenaandNatrinemashow a very close relationship, with some species being shown to overlap in ...

Microbial Communities in Sediments From Four Mildly Acidic Ephemeral Salt Lakes in the Yilgarn Craton (Australia) – Terrestrial Analogs to Ancient Mars

Frontiers in Microbiology, 2019
The Yilgarn Craton in Australia has a large number of naturally occurring shallow ephemeral lakes underlain by a dendritic system of paleodrainage channels.

A haloarchaeal ferredoxin electron donor that plays an essential role in nitrate assimilation [PDF]

, 2011
In the absence of ammonium, many organisms, including the halophilic archaeon Haloferax volcanii DS2 (DM3757), may assimilate inorganic nitrogen from nitrate or nitrite, using a ferredoxin-dependent assimilatory NO3-/NO2- reductase pathway.

Archaeal Communities in a Heterogeneous Hypersaline‐Alkaline Soil

Archaea, Volume 2015, Issue 1, 2015., 2015
In this study the archaeal communities in extreme saline‐alkaline soils of the former lake Texcoco, Mexico, with electrolytic conductivities (EC) ranging from 0.7 to 157.2 dS/m and pH from 8.5 to 10.5 were explored. Archaeal communities in the 0.7 dS/m pH 8.5 soil had the lowest alpha diversity values and were dominated by a limited number of ...

Halocatena pleomorpha gen. nov. sp. nov., an extremely halophilic archaeon of family Halobacteriaceae isolated from saltpan soil

International Journal of Systematic and Evolutionary Microbiology, 2020
A novel archaeal strain designated as SPP-AMP-1T was isolated from saltpan soil, using the serial dilution method on a halophilic archaeal medium supplemented with ampicillin. Cells were both rod-shaped and pleomorphic in nature, non-motile, unable to produce acid from a variety of sugars or grow anaerobically with different substrates (l-arginine) and

Diversity and Distribution of Archaea in the Mangrove Sediment of Sundarbans

Archaea, Volume 2015, Issue 1, 2015., 2015
Mangroves are among the most diverse and productive coastal ecosystems in the tropical and subtropical regions. Environmental conditions particular to this biome make mangroves hotspots for microbial diversity, and the resident microbial communities play essential roles in maintenance of the ecosystem.
