| transfer of the bacteriochlorophyll b-containing phototrophic bacteria rhodopseudomonas viridis and rhodopseudomonas sulfoviridis to the genus blastochloris gen. nov. | the phylogenetic positions of the bacteriochlorophyll (bchl) b-producing budding phototrophic bacteria rhodopseudomonas viridis and rhodopseudomonas sulfoviridis were studied on the basis of 16s rrna gene sequence information. these bacteria formed a tight cluster with the genus rhodoplanes as a sister group within the alpha-2 subgroup of the proteobacteria. genomic dna-dna hybridization assays showed that r. viridis and r. sulfoviridis were closely related but were different species. creation o ... | 1997 | 8995826 |
| biodiversity of amoebae and amoeba-resisting bacteria in a hospital water network. | free-living amoebae (fla) are ubiquitous organisms that have been isolated from various domestic water systems, such as cooling towers and hospital water networks. in addition to their own pathogenicity, fla can also act as trojan horses and be naturally infected with amoeba-resisting bacteria (arb) that may be involved in human infections, such as pneumonia. we investigated the biodiversity of bacteria and their amoebal hosts in a hospital water network. using amoebal enrichment on nonnutrient ... | 2006 | 16597941 |
| first report of human infection by rhodoplanes sp., alphaproteobacteria in china. | we isolated a novel strain of alphaproteobacteria from a patient, who had medical history of chronic rhinitis for more than twenty years and recently experienced local skin abscess and ulcer. he eventually died of multiple organ failure due to multi-antibiotics resistance. we identified the microorganism by 16srrna sequencing and found that it belonged to the genus rhodoplanes. it was named as rhodoplanes sp. strain zlj-0. it is resumed that rhodoplanes sp. strain zlj-0 might be an emerging huma ... | 2011 | 21771463 |
| rhodoplanes piscinae sp. nov. isolated from pond waters. | two strains (ja266t and ja333) of gram-negative, rod shaped, phototrophic, purple nonsulfur bacteria were isolated from a freshwater fish pond and an industrial effluent. both phototrophic and chemotrophic growth is possible by both strains. bacteriochlorophyll a and carotenoids of the spirilloxanthin series were present as photosynthetic pigments. major fatty acid for both strains is c18:1ω7c (>65 %) with minor amounts of 11methyl c18:1ω7c, c16:0, c16:1ω7c and c18:0 also present. lamellar type ... | 2012 | 22228659 |
| rhodoplanes pokkaliisoli sp. nov., a phototrophic alphaproteobacterium isolated from a waterlogged brackish paddy soil. | a gram-negative, rod-shaped, purple non-sulfur bacterial strain, designated ja415t, was isolated from the mud of a pokkali rice field located on vypeen island, ernakulam, kerala, india. strain ja415t was motile by means of a single polar flagellum. photo- and chemo-organoheterotrophic growth was observed using organic compounds as carbon sources and electron donors. photo- and chemolithoautotrophic growth using thiosulfate as electron donor did not occur. fermentative growth could not be demonst ... | 2009 | 19605702 |
| rhodoplanes serenus sp. nov., a purple non-sulfur bacterium isolated from pond water. | a bright pink to red-coloured, phototropic, purple non-sulfur bacterium, designated strain tut3530(t), was isolated from pond water. cells of the novel isolate were found to be gram-negative, motile, budding rods. cell extracts from phototrophically grown cultures had absorption maxima at 378, 482, 512, 550, 590, 800 and 850 nm, indicating the presence of bacteriochlorophyll a and carotenoids of the spirilloxanthin series. the intracytoplasmic membrane system was of the lamellar type. anaerobic ... | 2009 | 19244435 |
| characterization of thermotolerant purple nonsulfur bacteria isolated from hot-spring chloroflexus mats and the reclassification of "rhodopseudomonas cryptolactis" stadtwald-demchick et al.1990 as rhodoplanes cryptolactis nom. rev., comb. nov. | | 2007 | 18187892 |
| [comparative study of the fatty acid composition of some groups of purple nonsulfur bacteria]. | the fatty acid composition (fac) of 43 strains of purple nonsulfur bacteria belonging to six genera--rubrivivax, rhodopseudomonas, rhodoplanes, blastochloris, rhodobium, and rhodomicrobium--was studied by capillary gas chromatography. the cultures were grown on standard medium under standard conditions. automatic identification of the fatty acid methyl esters and statistical processing of the results were performed by the computerized microbial identification system (m.i.s). significant differen ... | 2007 | 18069321 |
