Biogeochemical and Molecular Signatures of Anaerobic Methane Oxidation in a Marine Sediment
TLDR
Molecular signatures of organisms present in the transition zone were detected by using selective PCR primers for sulfate-reducing bacteria and for Archaea and revealed that they all belonged to a novel deeply branching lineage of diverse DSR gene sequences not related to any previously described DSR genes. Expand
Ecophysiology of abundant denitrifying bacteria in activated sludge.
TLDR
The coexistence of Aquaspirillum, Azoarcus and Thauera-related bacteria in a range of treatment plants with differences in wastewater, design and operation suggest that the populations ensure a functional stability of the plants by occupying different ecological niches related to the carbon transformation. Expand
Biofilms in chronic infections - a matter of opportunity - monospecies biofilms in multispecies infections.
TLDR
The observations of the chronic biofilm infections point toward a trend of low bacterial diversity and sovereign monospecies biofilm aggregates even though the infection in which they reside are multispecies, while commensal and natural biofilm aggregation contain multiple species that are believed to coexist, interact and form biofilms with high bacterial and niche diversity. Expand
Identification and Ecophysiological Characterization of Epiphytic Protein-Hydrolyzing Saprospiraceae (“Candidatus Epiflobacter” spp.) in Activated Sludge
TLDR
A new genus, “Candidatus Epiflobacter,” is proposed for this epiphytic group in activated-sludge treatment plants, where it presumably plays an important role in protein degradation. Expand
The bacteriology of chronic venous leg ulcer examined by culture‐independent molecular methods
TLDR
The differences between the results obtained with culture‐based and molecular‐based approaches demonstrate that the use of one approach alone is not able to identify all of the bacteria present in the wounds. Expand
Bacterial influence on amino acid enantiomerization in a coastal marine sediment
TLDR
The distribution of amino acid isomers in Aarhus Bay sediment demonstrated that bacterial peptidoglycan contributed to the pool of organic nitrogen (the four analyzed D-amino acids made up about 3% of particulate organic nitrogen [PON]). Expand
Identity, abundance and ecophysiology of filamentous Chloroflexi species present in activated sludge treatment plants.
TLDR
The experiments revealed that Chloroflexi constituted a specialized group of filamentous bacteria only active under aerobic conditions consuming primarily carbohydrates, suggesting growth on complex polysaccharides. Expand
Diversity of sulfate-reducing bacteria from an extreme hypersaline sediment, Great Salt Lake (Utah).
TLDR
The growth performance of isolates and of the enrichment cultures suggests that the sediment SRB community of the northern arm of Great Salt Lake consists of moderate halophiles, which are salt-stressed at the in situ salinity of 27%. Expand
Identity, abundance and ecophysiology of filamentous bacteria belonging to the Bacteroidetes present in activated sludge plants.
TLDR
A comprehensive study on the ecophysiology of probe-defined Bacteroidetes populations was conducted on Danish and Czech samples and revealed that they were specialized bacteria involved in degradation of sugars, and may participate in the conversion of lipopolysaccharides and peptidoglycan liberated by decaying cells. Expand
Variations in microcolony strength of probe-defined bacteria in activated sludge flocs.
TLDR
The large difference between the different phylogenetic groups indicated that only a few species were present within each group, rather than many different bacterial species within each phylogenetic group had similar floc properties. Expand
