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

Archives of Microbiology, 2007
An alkaliphilic purple sulfur bacterium, strain SC5, was isolated from Soap Lake, a soda lake located in east central Washington state (USA). Cells of strain SC5 were gram-negative, non-motile, and non-gas vesiculate cocci, often observed in pairs or tetrads. In the presence of sulfide, elemental sulfur was deposited internally.

[On the ecology of marine chromatiaceae and chlorobiaceae (author's transl)].

Annales de microbiologie, 1976
Number and genera (types) of phototrophic red and green sulfur bacteria have been determined in the upper layer of eleven marine sediment samples from the euphotic zone in the Mediterranean Sea. Origin and nature of the sediment samples are given as well as their pH, total nitrogen and sulfide content.

Nickel requirement for the formation of active urease in purple sulfur bacteria (Chromatiaceae)

Archives of Microbiology, 1988
Nickel was found to be required for expression of urease activity in batch cultures of Thiocapsa roseopersicina strain 6311, Chromatium vinosum strain 1611 and Thiocystis violacea strain 2311, grown photolithotrophically with NH4Cl as nitrogen source. In a growth medium originally free of added nickel and EDTA, the addition of 0.1–10 μM nickel chloride

Urease formation in purple sulfur bacteria (Chromatiaceae) grown on various nitrogen sources

Archives of Microbiology, 1986
Batch cultures of Thiocapsa roseopersicina strain 6311, Thiocystis violacea strain 2311 and Chromatium vinosum strain 1611, grown anaerobically in the light on sulfide with urea, ammonia, N2 or casein hydrolysate as nitrogen source exhibited urease activity, while Chromatium vinosum strain D neither showed any degradation of urea nor urease activity on

Puf operon sequences and inferred structures of light-harvesting complexes of three closely related Chromatiaceae exhibiting different absorption characteristics

Archives of Microbiology, 2011
Whole cells of the purple sulfur bacterium strain 970 exhibit an unusual absorption peak at 963 nm. Its closest relatives, Thiorhodovibrio (Trv.) winogradskyi DSM6702(T) and strain 06511 display a bacteriochlorophyll (BChl) a absorption peak at 867 nm that is characteristic for most light-harvesting complexes 1 (LHC1) of proteobacteria. The puf operons
