Rhodobaca barguzinensis sp. nov., a new alkaliphilic purple nonsulfur bacterium isolated from a soda lake of the Barguzin Valley (Buryat Republic, Eastern Siberia)
TLDR
A novel strain, alga-05, of alkaliphilic purple nonsulfur bacteria was isolated from sediments of a small saline soda lake near Lake Algin (Barguzin Valley, Buryat Republic, Russia), and was described as a new species of the genus Rhodobaca.
Roseococcus suduntuyensis sp. nov., a new aerobic bacteriochlorophyll a-containing bacterium isolated from a low-mineralized soda lake of Eastern Siberia
TLDR
A novel strain, SHET, of aerobic bacteriochlorophyll a-containing bacteria was isolated from the surface layer of bottom sediments from the soda lake Shuluutai-Ekhe-Torom (Chita oblast, Eastern Siberia, Russia) and demonstrated to be a facultative alkaliphile and reduces nitrates to nitrites.
Light-harvesting complexes from purple sulfur bacteria Allochromatium minutissimum assembled without carotenoids.
TLDR
The results show that although the presence of Car molecules is important for the stability of the LH2 complexes the overall native structure can be maintained without any Cars at least in the case of purple sulfur bacteria.
Ectothiorhodosinus mongolicum gen. nov., sp. nov., a New Purple Bacterium from a Soda Lake in Mongolia
A new nonmotile purple sulfur bacterium (strain M9) was isolated from the steppe soda lake Lake Dzun Uldziin Nur (pH 9.4; mineralization, 3.3%) situated in southeastern Mongolia. Individual cells
Rubribacterium polymorphum gen. nov., sp. nov., a novel alkaliphilic nonsulfur purple bacterium from an Eastern Siberian soda lake
TLDR
An alkaliphilic nonsulfur purple bacterial strain “Green” was isolated from sediments of the littoral zone of the soda lake in the Barguzin River valley (Eastern Siberia) and analysis of 16S rRNA gene sequences revealed a 10% difference with the most closely related NPB (Rhodobacter species).
[Ectothiorhodosinus mongolicum gen. nov., sp. nov.,--a new purple sulfur bacterium from soda lake in Mongolia].
A new purple sulfur bacterium (strain M9) was isolated from the steppe soda Lake Dzun Uldziin Nur (pH 9.4; mineralization, 3.3%) situated in southeastern Mongolia. Individual cells appear as vibrios
Corrigendum to: Fluorescence of native and carotenoid‐depleted LH2 from Chromatium minutissimum, originating from simultaneous two‐photon absorption in the spectral range of the presumed (optically

Heterogeneity of carotenoid content and composition in LH2 of the purple sulphur bacterium Allochromatium minutissimum grown under carotenoid-biosynthesis inhibition
TLDR
It is shown that the LH2 can be assembled without any Cars, although the presence of Cars, however, is important for structural stability of LH2 complexes.
The LH2 complexes are assembled in the cells of purple sulfur bacterium Ectothiorhodospira haloalkaliphila with inhibition of carotenoid biosynthesis
TLDR
DPA almost entirely inhibits the biosynthesis of the colored Cars in Ect.haloalkaliphila cells, suggesting that the principles for assembling this LH2 complex in vivo in the absence of colored Cars remain the same.
Investigation of the neighbour relationships between photosystem II polypeptides in the two types of isolated reaction centres (D1/D2/cytb 559 and CP47/D1/D2/cyt b 559 complexes)
TLDR
The nearest neighbour relationships within the PSIIRC and the CP47/D1/D2/cyt b 559 complex were investgated by using different length bifunctional crosslinking agents.
