Salt resistance genes revealed by functional metagenomics from brines and moderate-salinity rhizosphere within a hypersaline environment

Frontiers in Microbiology, 2015
Hypersaline environments are considered one of the most extreme habitats on earth and microorganisms have developed diverse molecular mechanisms of adaptation to withstand these conditions.

Salinity-Dependent Species Richness of Bacillariophyta in Hypersaline Environments

, 2023
Hypersaline habitats are among the most polyextreme habitats on Earth, but they contain a rather large diatom species diversity. A review of the diatom species’ richness was made on three scales: 1. a separate lake in Crimea; 2.

Toxicity at the Edge of Life: A Review on Cyanobacterial Toxins from Extreme Environments

Marine Drugs, 2017
Cyanotoxins are secondary metabolites produced by cyanobacteria, of varied chemical nature and toxic effects. Although cyanobacteria thrive in all kinds of ecosystems on Earth even under very harsh conditions, current knowledge on cyanotoxin distribution

Metabolic Potential of Microbial Communities in the Hypersaline Sediments of the Bonneville Salt Flats

mSystems, 2022
The Bonneville Salt Flats (BSF) appear to be entirely desolate when viewed from above, but they host rich microbial communities just below the surface salt crust. In this study, we investigated the metabolic potential of the BSF microbial ecosystem.

Methanogens and Methanogenesis in Hypersaline Environments

, 2018
Methanogenesis is controlled by redox potential and permanency of anaerobic conditions; and in hypersaline environments, the high concentration of terminal electron acceptors, particularly sulfate, is an important controlling factor.

Morphological Characteristics of Mangroves in Saltwater Lakes under Hypersaline Conditions in Gili Meno North Lombok, Indonesia

Jurnal Inovasi Pendidikan dan Sains
Mangrove ecosystem is an environment formed from the interaction between land and sea waters, playing an important role as a natural protector of the coast from abrasion, tsunamis, and supporting biodiversity.

Land birds on atolls: diversity, origin, and function

Biological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Biodiversity and culture of prokaryotes inhabiting haloalkaline and meromictic Soap Lake, Washington, USA

Frontiers in Microbiology
Despite their potential for harboring novel microorganisms exhibiting beneficial metabolisms or that produce useful products for biotechnology and industry, alkaline lakes and soils are among the least studied extreme environments.

Biodegradation of petroleum hydrocarbons in hypersaline environments [PDF]

Brazilian Journal of Microbiology, 2012
Literature on hydrocarbon degradation in extreme hypersaline media presents studies that point to a negative effect of salinity increase on hydrocarbonoclastic activity, while several others report an opposite tendency. Based on information available in the literature, we present a discussion on the reasons that justify these contrary results.

Protein‐Independent Liquid–Liquid Phase Separation of Adenosine Triphosphate Under Crowded Conditions

Chemistry – A European Journal, EarlyView.
ATP itself is able to undergo liquid–liquid phase separation in the presence of the macromolecular crowding agent PEG and physiological ATP concentrations are sufficient for phase separation in the presence of mM Mg2+ and crowders, mimicking intracellular conditions.
