Performance Characteristics of qPCR Assays Targeting Human- and Ruminant-Associated Bacteroidetes for Microbial Source Tracking across Sixteen Countries on Six Continents
TLDR
It is demonstrated that stable target populations required for marker-based MST occur around the globe, and tested ruminant-targeted assays appear to be suitable quantitative MST tools beyond the regional level while the targeted human-associated populations seem to be less prevalent and stable, suggesting potential for improvements in human- Targeted methods. Expand
Occurrence of human-associated Bacteroidetes genetic source tracking markers in raw and treated wastewater of municipal and domestic origin and comparison to standard and alternative indicators of
TLDR
The potential of human-associated GeBaM to complement wastewater impact monitoring based on the determination of SFIB is highlighted and human-specific JC polyomaviruses and adenoviruses seem to be a valuable support if highly specific markers are needed. Expand
Phylogenetic and physiological characterization of a "Nostocoida limicola"-like organism isolated from activated sludge.
Ten strains of "Nostocoida limicola"-like organisms were isolated from a municipal wastewater treatment plant with minor industrial effluent. The near complete 16S rDNA sequences were determined forExpand
Population density and enzyme activities of heterotrophic bacteria in sewer biofilms and activated sludge
Abstract The heterotrophic activity of different wastewater biocenoses is assessed. The biofilms originate from a sewer discharging domestic wastewater and from a sewer discharging trade wastewaterExpand
Scum in Activated Sludge Plants: Impact of Non‐filamentous and Filamentous Bacteria
Excessive scum production is a widespread phenomenon in present activated sludge wastewater treatment. The question how foaming is initiated and stabilized is still unanswered. Hydrophobic wastewaterExpand
Filamentous scum bacteria in activated sludge plants: detection and identification quality by conventional activated sludge microscopy versus fluorescence in situ hybridization.
TLDR
Comparing detection, identification, and quantification quality of filamentous "scum bacteria" found by conventional activated sludge microscopy and fluorescence in situ hybridization (FISH) finds filamentous Microthrix parvicella and Eikelboom morphotype results correspond well. Expand
Specific binding of aluminium and iron ions to a cation-selective cell wall channel of Microthrix parvicella.
TLDR
The cell wall channel of Microthrix parvicella contains a binding site for polyvalent cations which may play a crucial role for the effect of heavy metals salts on M. par vicella-dominated activated sludge. Expand
Global Distribution of Human-Associated Fecal Genetic Markers in Reference Samples from Six Continents
TLDR
Results suggest that several genetic markers have considerable potential for measuring human-associated contamination in polluted environmental waters, which will be helpful in water quality monitoring, pollution modeling and health risk assessment to guide target-oriented water safety management across the globe.
