Methanogens and Methanogenesis in Hypersaline Environments
2010Methanogenesis in hypersaline environments is determined by redox potential and permanency of anaerobic conditions, and by the concentration of other terminal electron acceptors, particularly sulfate, because sulfate-reducing bacteria have a greater affinity than methanogens for competitive substrates like hydrogen and acetate.

Structure and Trophic Relations in Hypersaline Environments
Biology Bulletin Reviews, 2020Hypersaline waters with a salinity exceeding 35 g/L are widely distributed on the planet (hypersaline lakes and lagoons, deep-water “lakes,” and pore waters of sea ice) and are among the most extreme habitats on Earth. The present work analyzes and summarizes the results of long-term research on hypersaline lake and lagoon ecosystems in the Crimea ...

Cyanobacterial Diversity and Halotolerance in a Variable Hypersaline Environment
Microbial Ecology, 2007The Great Salt Plains (GSP) in north-central Oklahoma, USA is an expansive salt flat (approximately 65 km(2)) that is part of the federally protected Salt Plains National Wildlife Refuge. The GSP serves as an ideal environment to study the microbial diversity of a terrestrial, hypersaline system that experiences wide fluctuations in freshwater influx ...

Life in Hypersaline Environments
2016Many microorganisms are adapted to life at high-salt concentrations. Halophilic representatives are found in each of the three domains of life: Archaea, Bacteria, and Eukarya. Halophilic viruses exist as well. In NaCl-saturated brines such as found in the northern part of Great Salt Lake, Utah, in a few other natural salt lakes, and in saltern ...

Microbial communities of halite deposits and other hypersaline environments
2022Large regions of Earth's surface are underlain by salt deposits that evaporated from ancient oceans and are populated by extreme halophilic microbes. While the microbiology of ancient evaporites has been well studied, the ecology of halite deposits and more recently formed NaCl "salticle" stalactite structures (speleothems) in a Triassic halite mine ...

Performance of Fungi in Low Temperature and Hypersaline Environments
1976During the past ten years we have observed a broad array of stress capabilities in common fungi including ability to grow in aqueous ammonia and other alkaline solutions, in acids, in the presence of heavy metals, and in various salt media at low temperature.

Halophiles: biology, adaptation, and their role in decontamination of hypersaline environments
World Journal of Microbiology and Biotechnology, 2016The unique cellular enzymatic machinery of halophilic microbes allows them to thrive in extreme saline environments. That these microorganisms can prosper in hypersaline environments has been correlated with the elevated acidic amino acid content in their proteins, which increase the negative protein surface potential.

Impact of Lipidomics on the Microbial World of Hypersaline Environments
2011Mass spectrometry analysis of the lipid extracts of saltern biomass represents a powerful tool to quickly obtain information on the presence of various archaeal and bacterial microorganisms in saltern ponds. In the last years, ESI-MS lipid profiling by a shotgun lipidomic approach has allowed the discovery of new lipid molecules in the membranes of ...

Methanogenic bacteria from hypersaline environments
Systematic and Applied Microbiology, 1986Summary Several strains of methanogenic bacteria were isolated from logoons in Crimea that ranged in salinity from 2.2% to 30%. All of the isolates were obligately halophilic, methylotrophic methanogens utilizing methylamines as the sole substrate for growth and each was unable to metabolise H 2 :CO 2 , acetate or formate. The strains differ in their
