Abstract What happens to tap water when you are away from home? Day-to-day stagnation in building plumbing can potentially result quality deterioration (e.g., lead release or pathogen proliferation), which is a major public health concern. However, little known about the microbial ecosystem processes systems, hindering development of biological monitoring strategies. Here, we track microbiome assembly situ, showing that bacterial community composition changes rapidly city supply following...
The applicability of 454 pyrosequencing to characterize bacterial biofilm communities from two water meters a drinking distribution system was assessed. Differences in diversity and composition were observed. A better understanding the ecology biofilms will allow for effective management quality systems.
ABSTRACT Water utilities in parts of the U.S. control microbial regrowth drinking water distribution systems (DWDS) by alternating postdisinfection methods between chlorination and chloramination. To examine how this strategy influences communities, an urban DWDS (population ≅ 40,000) with groundwater as source was studied for approximately 2 years. samples were collected at five locations network different seasons analyzed their chemical physical characteristics community composition...
Water is essential for the sustainable development of human society. With largest population and rapid economic development, water usage treatment in China have grown tremendously past decades. In order to prevent pollution, standards wastewater effluent discharge been gradually developed implemented since 1973. After during over 40 years, numerous milestones achieved terms infrastructure coverage, standard policy system establishment, technological innovations. this article, we reviewed...
Wastewater-based testing (WBT) for SARS-CoV-2 has rapidly expanded over the past three years due to its ability provide a comprehensive measurement of disease prevalence independent clinical testing. The development and simultaneous application WBT measured biomarkers research activities pursuit public health goals, both areas with well-established ethical frameworks. Currently, practitioners do not employ standardized review process, introducing potential adverse outcomes professionals...
While drinking water biofilms have been characterized in various distribution systems (DWDS), little is known about the impact of different DNA extraction methods on subsequent analysis microbial communities biofilms. Since shown to affect outcome community other environments, it necessary select a method prior application molecular tools characterize complex ecology DWDS. This study compared quantity and quality yields from selected DWDS bacteria with cell wall properties using five widely...
Worldwide, it is common that the drinking water distribution systems (DWDSs) may be subjected to changes of supply quality due needs upgrading treatment processes or switching source water. However, potential impacts changed on stabilized ecological niches within DWDSs and associated deterioration risks were poorly documented. In present study, such transition effects caused by changing resulted from destabilization biofilm loose deposits in DWDS investigated analyzing physiochemical...
Abstract This study assessed the characteristics of and changes in suspended particles associated bacteria an unchlorinated drinking water distribution system its reservoirs with different sources. The results show that particle-associated (PAB) were present at a level 0.8–4.5 × 10 3 cells ml −1 biological activity 0.01–0.04 ng l ATP. Different PAB communities waters produced from sources revealed by 16S rRNA-based pyrosequencing analysis. quantified biomass underestimation due to multiple...
Recent applications of wastewater-based epidemiology (WBE) have demonstrated its ability to track the spread and dynamics COVID-19 at community level.
This study evaluated the continuous impact of monochloramine disinfection on laboratory-grown biofilms through characterization biofilm architecture and microbial community structure. Biofilm development were achieved using CDC (Centers for Disease Control Prevention) reactor systems with polyvinyl chloride (PVC) coupons as substratum sand filter-pretreated groundwater source seeding growth nutrient. After 2 weeks growth, subjected to chloramination 8 more at concentrations 7.5±1.4 9.1±0.4...
ABSTRACT The hospital environmental microbiome, which can affect patients’ and healthcare workers’ health, is highly variable the drivers of this variability are not well understood. In study, we collected 37 surface samples from neonatal intensive care unit (NICU) in an inpatient before after operation began. Additionally, workers 160 five additional areas hospital. All were analyzed using 16S rRNA gene amplicon sequencing, by cultured. NICU exhibited similar alpha beta diversities opening,...
Microbiomes play an essential role in promoting host health and fitness fishes, but the factors driving variation gut microbiomes among individuals are not fully recognized. Understanding biological environmental influencing microbiome fishes is needed to link composition physiology potentially design manipulations improve rearing success fisheries aquaculture. In this study, we characterized of Atlantic salmon (Salmo salar), a globally important species commercial aquaculture recreational...
Methods to quantitatively synthesize findings across multiple studies is an emerging need in wastewater-based epidemiology (WBE), where disease tracking through wastewater analysis performed at broad geographical locations using various techniques facilitate public health responses. Meta-analysis provides a rigorous statistical procedure for research synthesis, yet the manual process of screening large volumes literature remains hurdle its application timely evidence-based Here, we evaluated...
