Marine salterns are habitats for a large variety of halophilic bacteria. In the anoxic zones, halophilic sulfur bacteria develop mainly at the sediment surface, but only a few of them have so far been isolated from such environments. Among the phototrophic sulfur bacteria that sometimes form purple layers underneath the green cyanobacterial layers, members of the generaEctothiodhodospira, Chromatium (C. salexigens), Thiocapsa (T. halophila) were isolated. They grow by using sulfide as an… 
Life in Hypersaline Environments
Many 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
Unique communities of anoxygenic phototrophic bacteria in saline lakes of Salar de Atacama (Chile): evidence for a new phylogenetic lineage of phototrophic Gammaproteobacteria from pufLM gene analyses.
This is the first comprehensive description of phototrophic bacterial communities in a salt lake of South America made possible only due to the application of the functional pufLM genes.
Salinity Responses of Benthic Microbial Communities in a Solar Saltern (Eilat, Israel)
ABSTRACT The salinity responses of cyanobacteria, anoxygenic phototrophs, sulfate reducers, and methanogens from the laminated endoevaporitic community in the solar salterns of Eilat, Israel, were
Communities of purple sulfur bacteria in a Baltic Sea coastal lagoon analyzed by puf LM gene libraries and the impact of temperature and NaCl concentration in experimental enrichment cultures.
For the first time, changes within a community of PSB were specifically analyzed using the photosynthetic reaction center genes pufL and M by RFLP and cloning experiments and a dramatic shift occurred at elevated temperatures when M arichromatium gracile became most prominent which was not detected at lower temperatures.
Characterization of the endoevaporitic microbial communities in a hypersaline gypsum crust by fatty acid analysis
We have used fatty acid analyses to study the community structure of a layered endoevaporitic microbial community within a gypsum crust that covers the bottom of a saltern evaporation pond in Eilat,
Microbial communities and processes within a hypersaline gypsum crust in a saltern evaporation pond (Eilat, Israel)
The gypsum crust thus becomes a paradigm for the study of a wide variety of microbial processes and their interrelationships in the presence of high salt concentrations.
Halophilic and Halotolerant Micro-Organisms from Soils
Hypersaline environments are extreme habitats in which several other factors, in addition to high salt content, may limit the growth of organisms. These additional factors include temperature, pH,
Novel green sulfur bacteria phylotypes detected in saline environments: ecophysiological characters versus phylogenetic taxonomy
The taxonomic significance of salt tolerance or requirements in green sulfur bacteria has been analyzed with environmental populations and enrichment cultures from several saline systems (inland and
Salts and Brines
Cyanobacteria form a major component of the biota of hypersaline environments including salt lakes, solar salterns, hypersaline lagoons, salt flats, and hypersaline sulfur springs. Light-exposed
Anoxygenic phototrophic bacteria from extreme environments
Anoxygenic phototrophic bacteria have conquered various types of habitats of extreme conditions of temperature, pH and salinity. A short overview is given on the species found, on the properties of


Isolation of Members of the Families Chromatiaceae and Chlorobiaceae
The green and purple sulfur bacteria (Chlorobiaceae and Chromatiaceae) are two physiological-ecological groups of anaerobic phototrophic bacteria with anoxygenic photosynthesis. The two groups
Thiocapsa halophila sp. nov., a new halophilic phototrophic purple sulfur bacterium
A new phototrophic sulfur bacterium has been isolated from a red layer in a laminated mat occurring underneath a gypsum crust in the mediterranean salterns of Salin-de-Giraud (Camargue, France).
A new purple sulfur bacterium from saline littoral sediments, Thiorhodovibrio winogradskyi gen. nov. and sp. nov.
Two strains of a new purple sulfur bacterium were isolated in pure culture from the littoral sediment of a saline lake (Mahoney Lake, Canada) and a marine microbial mat from the North Sea island of Mellum, respectively and exhibited high specific respiration rates.
Phototrophic sulfur bacteria and sulfate-reducing bacteria causing red waters in a shallow brackish coastal lagoon (Prévost Lagoon, France)
In the shallow lagoon of Prevost, red waters occurring periodically during warm summers are a consequence of a succession of ecological events beginning in the early spring with a bloom of algae, and a red water was analyzed in summer 1977, showing the active oxidation of sulfide by phototrophic bacteria.
Rhodospirillum salinarum sp. nov., a halophilic photosynthetic bacterium isolated from a Portuguese saltern
A new species of halophilic photosynthetic bacteria, Rhodospirillum salinarum, has been isolated and described and growth requirements are complex, yeast extract and peptone being required both for aerobic heterotrophic and for anaerobic phototrophic growth.
Competition for sulfide among colorless and purple sulfur bacteria in cyanobacterial mats.
The balance between O2 and light penetration down into the sulfide zone thus determined in micro-scale which type of sulfur bacteria became dominant, and purple sulfur bacteria (Chromatium sp.) were the dominant sulfide oxidizers.
Ectothiorhodospira marismortui sp. nov., an obligately anaerobic, moderately halophilic purple sulfur bacterium from a hypersaline sulfur spring on the shore of the Dead Sea
The isolate of a novel type of purple sulfur bacterium was isolated from a hypersaline sulfur spring on the shore of the Dead Sea is described as a new species, and the name Ectothiorhodospira marismortui sp.
Ectothiorhodospira halochloris sp. nov., a new extremely halophilic phototrophic bacterium containing bacteriochlorophyll b
A new bacteriochlorophyll b containing phototrophic bacterium was isolated from extremely saline and alkaline soda lakes in Egypt using a synthetic medium with high contents of sodium carbonate, sodium sulfate and sodium chloride to create a new organism described as Ectothiorhodospira halochloris.
Gram-Negative Mesophilic Sulfate-Reducing Bacteria
The utilization of polysaccharides or polypeptides, such as has been observed with the extremely thermophilic sulfate-reducing archaebacterium Archaeoglobus (Stetter, 1988; Stetter et al., 1987), has not been reported for mesophobic sulfate reducers.
