Abstract From the microbial mats that develop in Solar Lake, a new purple sulfur bacterium was isolated. This strain (Chromatium strain SL 3201) was morphologically similar to Chromatium gracile and Chromatium minutissimum. Chromatium SL 3201 was found to be a moderate halophile with a growth range between 2 and 20% NaCl (optimum 4–5% NaCl) and was able to grow photo-organotrophically using glycolate and glycerol. It is the first described phototrophic sulfur bacterium able to use glycolate… 

Thiocapsa imhoffii, sp. nov., an alkaliphilic purple sulfur bacterium of the family Chromatiaceae from Soap Lake, Washington (USA)

The unique assemblage of physiological and phylogenetic properties of strain SC5 defines it as a new species of the genus Thiocapsa, and it is described herein as Tca.

Marichromatium indicum sp. nov., a novel purple sulfur gammaproteobacterium from mangrove soil of Goa, India.

On the basis of 16S rRNA gene sequence analysis and its morphological and physiological characteristics, strain JA100(T) is sufficiently different from other Marichromatium species to justify its designation as a novel species, for which the name Marichromaatium indicum sp.

Halochromatium roseum sp. nov., a non-motile phototrophic gammaproteobacterium with gas vesicles, and emended description of the genus Halochromatium.

The morphological and physiological differences of strainJA134(T) from other Halochromatium species support the description of strain JA134 (T) as the type strain of a novel species, Halochromaatium roseum sp.

Haloanaerobacter salinarius sp. nov., a novel halophilic fermentative bacterium that reduces glycine-betaine to trimethylamine with hydrogen or serine as electron donors; emendation of the genus Haloanaerobacter.

Strain SG 3903T, a novel halophilic fermentative bacterium isolated from the black sediment below a gypsum crust and a microbial mat in hypersaline ponds of Mediterranean salterns, represents the first described strain in the genus Haloanaerobacter capable of the Stickland reaction with two amino acids.

Thiorhodococcus minus, gen. nov., sp. nov., a new purple sulfur bacterium isolated from coastal lagoon sediments

Morphological characteristics of strain CE2203 indicated a close affiliation to the genera Thiocystis and Thiocapsa, but the phylogenetic treeing revealed no closer relationship to Thiokapsa roseopersicina or other known members of the Chromatiaceae.

It is clear from polyphasic evidence that the isolate merits the status of genus in the gamma subclass of the Proteobacteria, and the name Hahella chejuensis gen. nov., sp.

Marichromatium bheemlicum sp. nov., a non-diazotrophic, photosynthetic gammaproteobacterium from a marine aquaculture pond.

Based on 16S rRNA gene sequence analysis, morphological and physiological characteristics and DNA-DNA hybridization studies, strain JA124(T) is sufficiently different from other Marichromatium species to merit its description as the type strain of a novel species, Marichromaatium bheemlicum sp.

Phylogenetic position of the purple sulfur bacterium Lamprobacter modestohalophilus determined based on the data on new strains of the species

Evidence is provided for the preservation of two phenotypically and phylogenetically different genera, Lamp Robacter and Halochromatium, Lpb.

It is suggested that salt concentrations of natural habitats are an important selective factor that determines the development of a selected range of phototrophic bacteria in an exclusive way, and as a consequence, the salt responses of these bacteria are reflected in their phylogenetic relationships.



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).

Isolation and characterization of Rhodovulum strictum sp. nov. and some other purple nonsulfur bacteria from colored blooms in tidal and seawater pools.

Several strains of phototrophic purple nonsulfur bacteria were isolated from colored blooms occurring in tidal and seawater pools in Japan. All of these isolates had ovoid to rod-shaped cells that

Anaerobic bacteria from hypersaline environments.

Three genera and five species of halophilic methylotrophic methanogens have been reported, and a bloom of phototrophic bacteria in the marine salterns of Salins-de-Giraud, located on the Mediterranean French coast in the Rhone Delta, is also described.

Photoexcretion and Fate of Glycolate in a Hot Spring Cyanobacterial Mat

Photosynthesis by Synechococcus lividus, the sole oxygenic phototroph inhabiting the surface of the 55 degrees C cyanobacterial mat in Mushroom Spring, Yellowstone National Park, causes superoxic and alkaline conditions which promote glycolate photoexcretion, which suggests that cross-feeding of glycolates from S. lividUS to filamentous heterotrophs occurs and that underestimation of the extent of photo Excretion is probable.


Short-term labelling experiments with [1-14C]glycollate and enzyme studies indicated that T. neapolitanus can metabolize glycollate via two pathways, and it was concluded that the glycine-serine pathway does not play a major role in glyCollate metabolism.

Growth and metabolism of the purple sulfur bacterium Thiocapsa roseopersicina under combined light/dark and oxic/anoxic regimens

The data showed that T. roseopersicina is very well adapted to cope with the combined oxygen and light regimes as they occur in microbial mats, which may explain the dominance of this bacterium in the purple layer of these sediment ecosystems.
