A Novel View of the Diversity of Anoxygenic Phototrophic Bacteria Inhabiting the Chemocline of Meromictic Karst Lakes [PDF]
The rates of oxygenic and anoxygenic photosynthesis, the microorganisms responsible for these processes, and the hydrochemical characteristics of the sulfide-containing karst lakes, Black Kichier and Big Kichier (Mari El Republic), were investigated.

Proliferation of purple sulphur bacteria at the sediment surface affects intertidal mat diversity and functionality. [PDF]
There is a relative absence of studies dealing with mats of purple sulphur bacteria in the intertidal zone. These bacteria display an array of metabolic pathways that allow them to disperse and develop under a wide variety of conditions, making these ...

Polar lipids in phototrophic bacteria of the Rhodospirillaceae and Chromatiaceae families [PDF]
The polar lipids of photosynthetic purple bacteria of the genera Chromatium, Thiocapsa, Thiocystis, Ectothiorhodospira, Rhodopseudomonas, Rhodospirillum, and Rhodomicrobium were analyzed. Characteristic compositions of the polar lipids were found for most of the Rhodospirillaceae and Chromatiaceae species. Phosphatidylethanolamine, phosphatidylglycerol,

Microbially driven methane and sulfur cycling processes and coupling mechanisms in mangrove sediments [PDF]
Background Methane (CH4) as a powerful greenhouse gas is the second largest contributor to global climate warming. Mangrove sediments are an important natural source of biogenic CH4 with rich organic carbon (C) and diverse sulfur (S) compounds, ideally ...

Chemical Analysis of Peptidoglycans from Species of Chromatiaceae and Ectothiorhodospiraceae
Abstract Rigid layer (sodium dodecylsulfate(SDS)-insoluble cell wall) and peptidoglycan fractions were obtained from the Chromatiaceae (Thiocysüs violacea and Chromatium tepidum) and from Ectothiorhodospira vacuolata. Chemical composition of rigid layers from all three species indicated the presence of peptidoglycan-bound protein.

Succession of Bacterial Communities in a Seasonally Stratified Lake with an Anoxic and Sulfidic Hypolimnion [PDF]
Although bacteria play key roles in aquatic food webs and biogeochemical cycles, information on the seasonal succession of bacterial communities in lakes is still far from complete.

Lipopolysaccharides of Thiocystis violacea, Thiocapsa pfennigii, and Chromatium tepidum, species of the family Chromatiaceae [PDF]
The lipopolysaccharides (LPS) of three species of purple sulfur bacteria (Chromatiaceae), Thiocystis violacea, Thiocapsa pfennigii, and the moderately thermophilic bacterium Chromatium tepidum, were isolated. The LPS of Thiocystis violacea and Chromatium tepidum contained typical O-specific sugars, indicating O-chains.

Conservation of the Family Name Chromatiaceae Bavendamm 1924 with the Type Genus Chromatium Perty 1852: Request for an Opinion [PDF]
The phototrophic red sulfur bacteria presently are placed in a family named Thiorhodaceae Molisch. However, this name is illegitimate because it was not based on the name of a genus. Of the genera placed in this family, five have familial names based on them.
