[physilogical and biochemical properties of bacteria of chromatium genus, isolated from water bodies enriched with hydrogen sulfide].	pure cultures of purple sulfur bacteria, which were attributed to genus chromatium, were isolated from water bodies of the yavoriv sulfur deposit. both cultures perform anoxygenic photosynthesis and contain bacteriochlorophyll a and carotenoids of spirilloxanthin group. isolated bacteria grow photolithoauthotrophically, photolithoheterotrophically and photoorganoheterotrophically. hydrogen sulphide, sulfur and thiosulfate were used as inorganic electron donors. bacteria were resistant to high hy ...	2009	20455432
chromatium species: an emerging bioindicator of crude oil pollution of tidal mud flats in the niger delta mangrove ecosystem, nigeria.	establishing microbiological indices for the monitoring of environmental decay by crude oil pollution in the niger delta region has been a major concern of our current researches. chromatium species, a purple, gram positive pleomorphic, motile, microaerophlic sulfur bacterium offers a good potential for use in the assessment of the short term effects of oil pollution of tidal mud flats in the niger delta mangrove ecosystem. its response to the november 22, 2003 spillage at the qua iboe estuary a ...	2009	18600468
sodium dodecyl sulfate-polyacrylamide gel protein electrophoresis of freshwater photosynthetic sulfur bacteria.	sodium dodecyl sulfate-polyacrylamide gel protein electrophoresis (sds-page) was carried out using different bacterial strains of the photosynthetic sulfur bacteria chlorobium, thiocapsa, thiocystis, and chromatium cultured in the laboratory, and the natural blooms in two karstic lakes (lake cisó and lake vilar, ne spain) where planktonic photosynthetic bacteria (purple and green sulfur bacteria) massively developed accounting for most of the microbial biomass. several extraction, solubilization ...	2011	20524118
investigation of the redox interaction between mn-bicarbonate complexes and reaction centers from rhodobacter sphaeroides r-26, chromatium minutissimum, and chloroflexus aurantiacus.	the change in the dark reduction rate of photooxidized reaction centers (rc) of type ii from three anoxygenic bacteria (rhodobacter sphaeroides r-26, chromatium minutissimum, and chloroflexus aurantiacus) having different redox potentials of the p(+)/p pair and availability of rc for exogenous electron donors was investigated upon the addition of mn(2+) and hco(3)(-). it was found that the dark reduction of p(870)(+) from rb. sphaeroides r-26 is considerably accelerated upon the combined additio ...	2011	22150281
vertical distribution of archaea and bacteria in a meromictic lake as determined by fluorescent in situ hybridization.	the prokaryotic cells distribution in the water column of the coastal saline meromictic lake faro (messina, italy) was investigated by microscopic counting techniques. water samples were collected at a central station from the surface to the bottom, when waters were characterized by a marked stratification. a "red-water" layer, caused by a dense growth of photosynthetic sulfur bacteria, was present at a depth of 15 m, defining a transition area between oxic (mixolimnion) and anoxic (monimolimnio ...	2012	22006072
