Filamentous Chloroflexi species are often present in activated sludge wastewater treatment plants relatively low numbers, although bulking incidences caused by filaments have been observed. A new species-specific gene probe for FISH was designed and using phylum-, subdivision-, morphotype 1851- probes, the abundance of were monitored samples from 126 industrial five European countries. 50% samples, quantities. In most could only be identified with phylum or subdivision indicating presence...
ABSTRACT Aquifer recharge presents advantages for integrated water management in the anthropic cycle, namely, advanced treatment of reclaimed and additional dilution pollutants due to mixing with natural groundwater. Nevertheless, this practice represents a health environmental hazard because presence pathogenic microorganisms chemical contaminants. To assess quality extracted from recharged aquifers, groundwater systems Torreele, Belgium, Sabadell, Spain, Nardò, Italy, were investigated...
Filamentous members of the Bacteroidetes are commonly observed in activated sludge samples originating from both municipal and industrial wastewater treatment plants (WWTP), where they occasionally can cause bulking. Several oligonucleotide 16S rRNA-targeted probes were designed to target filaments with a needle-like appearance similar Haliscomenobacter hydrossis. The design these was based on an isolate sequence obtained micromanipulated filament. abundance filamentous determined 126...
The processes that control water quality improvement during artificial recharge (filtering, degradation, and adsorption) can be enhanced by adding a reactive barrier containing different types of sorption sites promoting diverse redox states along the flow path, which increases range pollutants degraded. While this option looks attractive for renaturazing reclaimed water, three issues have to analyzed prior broad scale application: (1) fair comparison between system with without barrier; (2)...
A laboratory scale sequencing batch reactor (SBR) operating for enhanced biological phosphorus removal (EBPR) and fed with a mixture of volatile fatty acids (VFAs) showed stable efficient EBPR capacity over four-year-period. Phosphorus (P), poly-beta-hydroxyalkanoate (PHA) glycogen cycling consistent classical anaerobic/aerobic were demonstrated the order anaerobic VFA uptake being propionate, acetate then butyrate. The SBR was operated without pH control 63.67 +/- 13.86 mg P l-1 released...
Once dispersed in water, plastic materials become promptly colonized by biofilm-forming microorganisms, commonly known as plastisphere.By combining DNA sequencing and Confocal Laser Scanning Microscopy (CLSM), we investigated the plastisphere colonization patterns following exposure to natural lake waters (up 77 days) of either petrochemical or biodegradable (low density polyethylene - LDPE, terephthalate PET, polylactic acid PLA, starch-based MaterBi® Mb) comparison planktonic community...
Activated sludge was submitted to aerobic dynamic substrate feeding for the production of biodegradable plastics. Two sequencing batch reactors were operated with acetate or propionate as sole carbon substrates. With a homopolymer polyhydroxybutyrate (PHB) obtained and copolymer hydroxybutyrate hydroxyvalerate P(HB/HV) produced. Three main morphotypes identified in both sludges: two belong Alphaproteobacteria class third Betaproteobacteria class. Bacilli belonging shown by FISH analysis,...
Summary Twelve strains of filamentous bacteria morphologically identified as ‘ Microthrix parvicella ’ were isolated from industrial activated sludge wastewater treatment plants. 16S rRNA gene sequences analysis showed that these all closely related to Candidatus parvicella’. Six them, however, had a similarity only 95.7% and 96.7% parvicella’ suggesting the presence new species. The name calida’ is proposed for this microorganism. physiological properties six isolates supported description...
"Candidatus Microthrix" bacteria are deeply branching filamentous actinobacteria which occur at the water-air interface of biological wastewater treatment plants, where they often responsible for foaming and bulking. Here, we report first draft genome sequence a strain from this genus: Microthrix parvicella" Bio17-1.
Managed aquifer recharge (MAR) is known to increase available water quantity and improve quality. However, its implementation hindered by the concern of polluting aquifers, which might lead onerous treatment regulatory requirements for source water. These make MAR unsustainable both economically energetically. To address these concerns, we tested reactive barriers laid at bottom infiltration basins enhance quality improvement during soil passage. The goal was (1) provide a range sorption...
The diversity of filamentous bacteria present in industrial wastewater treatment plants was analysed by a combination classical and molecular-biological approaches. Many unknown were observed about 80 screened activated sludge samples from different industries with sometimes severe bulking problems. A special focus paid to filaments which resembled "Nostocoida limicola", bacterium found be many WWTPs. These are hardly cultivable only one strain obtained maintained co-culture yeast. 16S rRNA...
