| pseudorhodoferax soli gen. nov., sp. nov. and pseudorhodoferax caeni sp. nov., two members of the class betaproteobacteria belonging to the family comamonadaceae. | a novel betaproteobacterium, strain tbea3(t), was isolated from soil using enrichment cultures with the organic thioether 3,3'-thiodipropionic acid as sole carbon and energy source. analysis of the 16s rrna gene sequence revealed 99.1 % sequence similarities to a poorly characterized member of the family comamonadaceae, strain sb1(t), which had been previously isolated from activated sludge. both strains showed highest gene sequence similarities (up to 96.9 %) to members of the genera rhodoferax ... | 2009 | 19625429 |
| proposals of curvibacter gracilis gen. nov., sp. nov. and herbaspirillum putei sp. nov. for bacterial strains isolated from well water and reclassification of [pseudomonas] huttiensis, [pseudomonas] lanceolata, [aquaspirillum] delicatum and [aquaspirillum] autotrophicum as herbaspirillum huttiense comb. nov., curvibacter lanceolatus comb. nov., curvibacter delicatus comb. nov. and herbaspirillum autotrophicum comb. nov. | two strains of curved bacteria, 7-1(t) and 7-2(t), isolated from well water, were phylogenetically examined to determine their taxonomic position. strain 7-1(t) is a gram-negative, slightly curved rod. analysis of the 16s rrna gene sequence showed that strain 7-1(t) formed a cluster with [aquaspirillum] delicatum and [pseudomonas] lanceolata. it has some similar characteristics to [a.] delicatum and [p.] lanceolata, but has sufficient distance to separate it from other genera. dna-dna hybridizat ... | 2004 | 15545462 |
| [experimental study of autotrophic denitrification bacteria through bioaugmentation of activated sludge from municipal wastewater plant]. | activated sludge of municipal wastewater treatment plant was domesticated by sulfur as the electron donor under autotrophic. the sludge activity was determined by measuring growth rate of sludge. the removal efficiency of nitrate and sulfate production efficiency were analyzed by continuously measuring the concentration of no3(-)-n and so4(2-). when the removal efficiency of nitrate was more than 90%, 16s rrna genetic libraries were built up to compare their microbial biodiversity. the growth ra ... | 2011 | 21717771 |
| changes in pelagic bacteria communities due to leaf litter addition. | in many limnetic systems, the input of allochthonous organic matter, e.g., leaf litter, is a substantial source of dissolved organic carbon (doc) for pelagic bacteria, especially in fall and winter when autochthonous doc production is low. however, relatively little is known about community changes of pelagic lake bacteria due to leaf litter input which includes both the release of leaf leachates and microorganisms from the leaf litter into the surrounding water. therefore, we have experimentall ... | 2010 | 20198369 |
| limnohabitans curvus gen. nov., sp. nov., a planktonic bacterium isolated from a freshwater lake. | a chemo-organotrophic, aerobic, facultatively anaerobic, non-motile strain, mwh-c5(t), isolated from the water column of the oligomesotrophic lake mondsee (austria), was characterized phenotypically, phylogenetically and chemotaxonomically. the predominant fatty acids of the strain were c(16 : 1)omega7c/omega6c, c(16 : 0), c(12 : 1) and c(8 : 0)-3oh, the major quinone was ubiquinone q-8 and the g+c content of the dna of the strain was 55.5 mol%. 16s rrna gene similarity to the closest related ty ... | 2010 | 19671731 |
| culturable diversity of heterotrophic bacteria in forlidas pond (pensacola mountains) and lundström lake (shackleton range), antarctica. | cultivation techniques were used to study the heterotrophic bacterial diversity in two microbial mat samples originating from the littoral zone of two continental antarctic lakes (forlidas pond and lundström lake) in the dufek massif (within the pensacola mountains group of the transantarctic mountains) and shackleton range, respectively. nearly 800 isolates were picked after incubation on several growth media at different temperatures. they were grouped using a whole-genome fingerprinting techn ... | 2011 | 21424822 |
| extracellular dna is abundant and important for microcolony strength in mixed microbial biofilms. | a new approach for quantification of extracellular dna (edna) in mixed biofilms at microscale resolution was developed and combined with other staining techniques to assess the origin, abundance and role of edna in activated sludge biofilms. most edna was found in close proximity to living cells in microcolonies, suggesting that most of it originated from an active secretion or alternatively, by lysis of a sub-population of cells. when the staining was combined with fluorescence in situ hybridiz ... | 2010 | 21118344 |
