Complex Effects of Cytochrome P450 Monooxygenase on Purple Membrane and Bacterioruberin Production in an Extremely Halophilic Archaeon: Genetic, Phenotypic, and Transcriptomic Analyses

Frontiers in Microbiology, 2018
Halophilic archaea are known to produce a diverse array of pigments for phototrophy and photoprotection. The aim of this paper was to determine the role of a Halobacterium gene encoding the predicted cytochrome P450 monooxygenase (CYP174A1) in pigment ...

Archaeal Cytoskeletal Protein CetZ1 Influences Assembly of the Motility Machinery

Molecular Microbiology, Volume 126, Issue 4, Page 433-450, October 2026.
The Haloferax volcanii tubulin‐like protein CetZ1 is required for rod‐cell morphogenesis and motility. We show that CetZ1 loss or GTPase inactivation impairs assembly of the motility machinery, including the archaellum base protein ArlD, the chemotaxis adaptor CheW1, and the response regulator CheY.

Test for the Production and Assay of the Proteolytic Activities of Halophilic Bacteria and Archaea Isolated from Algerian Hypersaline Environments

Proceedings, 2020
: The present work was carried out on 133 halophilic strains isolated on MGM (Modified Growth Medium) medium with 12 and 23% (w/v) of salt. A screening of the extracellular proteolytic activities, carried out on the same medium supplemented with casein ...

Underutilized microbial diversity in sub‐Saharan Africa: Toward context‐driven microbiome‐based agricultural interventions

Agronomy Journal, Volume 118, Issue 5, September/October 2026.
Abstract Microbiome‐based approaches are increasingly recognized as sustainable and complementary strategies for overcoming persistent constraints in agricultural production. In this article, we synthesize existing evidence on microbiome applications in sub‐Saharan Africa (SSA) aimed at resolving major binding constraints compromising sustainable crop ...

Characterization of Growth and Ultraviolet Light Resistance in Four Novel Halophilic Archaea Isolates [PDF]

, 2020
The goal of this project was to characterize the growth and UV resistance of four unique halophilic strains, JOR-1, BOL 4-2, BOL 6-1 and BOL 5-4. Halophilic archaea are interesting to study in part because of their notably high UV resistance.

Threats and Shifts in Microbial Communities of Salars Associated With Direct Lithium Extraction and Brine Reinjection

Global Challenges, Volume 10, Issue 9, September 2026.
Lithium for rechargeable batteries is increasingly extracted from brines in high‐Andean salars. Direct Lithium Extraction (DLE) technologies are promoted as sustainable alternatives to conventional evaporation ponds. This work explores how brine modification and reinjection may affect microbial communities and ecosystem functioning, highlighting the ...

Brine Pool Microbes Enrich Metalliferous Sediments in Salt Giant Basins

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract We report the discovery of an extinct deep‐sea brine pool in the Red Sea's Hume Deep, providing evidence that rift‐shoulder pools are ephemeral on millennial timescales, and that the microbially‐enriched metalliferous deposits produced during the pool's active phase persist into the stratigraphic record.

A Genetic Investigation of the KEOPS Complex in Halophilic Archaea

PLoS ONE, 2012
KEOPS is an important cellular complex conserved in Eukarya, with some subunits conserved in Archaea and Bacteria. This complex was recently found to play an essential role in formation of the tRNA modification threonylcarbamoyladenosine (t(6)A), and was previously associated with telomere length maintenance and transcription.

Genetic manipulation of Methanosarcina spp.

Frontiers in Microbiology, 2012
The discovery of the third domain of life, the Archaea, is one of the most exciting findings of the last century. These remarkable prokaryotes are well known for their adaptations to extreme environments; however, Archaea have also conquered moderate ...
