[Glycerin metabolism in purple sulfur bacteria].

Mikrobiologiia, 1979
The purple sulfur bacteria Thiocapsa roseopersicina, strains BBS and SL-4, and Lamprobacter modestohalophilus assimilate glycerol when grown in the light under the anaerobic conditions or in the dark under the aerobic conditions. Apart from glycerol, the bacteria require for their growth reduced sulfur compounds (thiosulfate) and bicarbonate.

[Purple sulfur bacteria isolated from reservoirs of the Yavoriv sulfur deposit].

Mikrobiolohichnyi zhurnal (Kiev, Ukraine : 1993), 2007
Three pure cultures of purple sulfur bacteria were isolated from reservoirs of the Yavoriv sulfur deposit. The studying of their morphology, cytology and physiology has confirmed the belonging of these bacteria to Chromatiaceae family and has allowed identifying them as Thiocapsa sp., Lamprocystis sp. and Chromatium sp.

Metabolism of Inorganic Sulfur Compounds in Purple Bacteria

2009
This chapter focuses on dissimilatory and assimilatory metabolism of inorganic sulfur compounds by the bacteriochlorophyll-containing purple bacteria. Many anoxygenic phototrophic purple bacteria use inorganic sulfur compounds (e.g., sulfide, elemental sulfur, polysulfides, thiosulfate, or sulfide) as electron donors for reductive carbon dioxide ...

THE PHOTOPHOBIC RESPONSE OF VARIOUS SULFUR AND NONSULFUR PURPLE BACTERIA

Photochemistry and Photobiology, 1989
Abstract— The photophobic response of 34 strains of nonsulfur and sulfur purple bacteria was examined with respect to response‐eliciting light intensities. The bacteria were grown in defined synthetic media or in Winogradsky columns. Two population methods based on Engelmann's light trap were used to determine the discrimination thresholds of the ...

Regulation of CO2 fixation in non-sulfur purple photosynthetic bacteria

2005
Our laboratory studies the regulation of CO2 fixation in phototrophic micro-organisms. The expression of genes encoding enzymes responsible for assimilating CO2 is primarily regulated by a LysR-type transcriptional activator, CbbR, that functions by binding specific sites in the promoter region of both the cbb I and cbb II CO2 fixation operons under ...

Taxonomy and Physiology of Phototrophic Purple Bacteria and Green Sulfur Bacteria

2006
Anoxygenic phototrophic bacteria have always attracted scientists because of their coloration and ability to perform photosynthesis in the absence of air and without producing oxygen. Despite this common feature of these bacteria, variation in morphological, physiological and molecular properties, including molecular structures of the photosynthetic ...

Swimming and Behavior in Purple Non-Sulfur Bacteria

2009
Many species of purple bacteria swim, and they direct that swimming towards carbon and nitrogen sources, light and/or oxygen using a complex set of chemosensory pathways. The review will illustrate how genomics, molecular biology, biochemistry, behavioral analysis and in vivo imaging have been used to try and dissect the pathways, identifying common ...

A Microsensor Study of the Interaction between Purple Sulfur and Green Sulfur Bacteria in Experimental Benthic Gradients

Microbial Ecology, 1999
> Abstract The interaction between the purple sulfur bacterium Thiocapsa roseopersicina and the green sulfur bacterium Prosthecochloris aestuarii was studied in a gradient chamber under a 16-hours light-8-hours dark regime. The effects of interaction were inferred by comparing the final outcome of a mixed culture experiment with those of the respective
