Behaviour of pathogenic and indicator bacteria during urban wastewater treatment and sludge composting, as revealed by quantitative PCR.
TLDR
Overall, differences in survival were observed for all bacteria studied, when submitted to the same environmental pressure, and this holds both for differences between indicators and pathogenic bacteria and between pathogenicacteria.About:

Detecting human bacterial pathogens in wastewater treatment plants by a high-throughput shotgun sequencing technique.
Lin Cai,Tong Zhang +1 more
TL;DR: 24 metagenomic DNA data sets derived from a high-throughput shotgun sequencing technique were employed to more accurately and efficiently detect human bacterial pathogens in influent, activated sludge, and effluent of two Hong Kong WWTPs to provide a comprehensive profile of commonly concerned human pathogens.

Achievements and Trends in Photoelectrocatalysis: from Environmental to Energy Applications
Guilherme G. Bessegato,Thais Tasso Guaraldo,Juliana Ferreira de Brito,Michelle Fernanda Brugnera,Maria Valnice Boldrin Zanoni +4 more
TL;DR: In this paper, the authors present a compiled and critical review of photoelectrocatalysis, trends and future prospects of the technique applied in environmental protection studies, hydrogen generation, and water disinfection, focusing on the applications of TiO2 and the production of nanometric morphologies with a great improvement in the photocatalyst properties useful for the degradation of organic pollutants, the reduction of inorganic contaminants, the conversion of CO2, microorganism inactivation and water splitting for hydrogen generation.

Pathogenic bacteria in sewage treatment plants as revealed by 454 pyrosequencing.
Lin Ye,Tong Zhang +1 more
TL;DR: This study applied 454 high-throughput pyrosequencing to analyze potentially pathogenic bacteria in activated sludge from 14 municipal wastewater treatment plants (WWTPs) across four countries, plus the influent and effluent of one of the 14 WWTPs.
Bioremediation을 활용한 수질정화
TL;DR: Bioremediation is the process of using bacteria and other biological enhancements under controlled conditions to control pollution caused by different components of gasoline and fuel oxygenates in the contaminated land and groundwater.

Quantitative Analysis of Small-Subunit rRNA Genes in Mixed Microbial Populations via 5′-Nuclease Assays
TL;DR: A newly developed quantitative PCR assay (5′-nuclease assay, also known as TaqMan) was applied to quantify specific small-subunit (SSU) rRNA genes (rDNAs) from uncultivated planktonic prokaryotes in Monterey Bay and accurately measured the proportions of genes in artificial mixtures.

Role of Nonhost Environments in the Lifestyles of Salmonella and Escherichia coli
TL;DR: The gram-negative bacterial species Salmonella enterica and Escherichia coli are members of the family Enterobacteriaceae that spend a good part of their lives as residents of animal hosts.

Viable but nonculturable stage of Campylobacter jejuni and its role in survival in the natural aquatic environment.

TL;DR: In all cases, increasing temperature of cultivation resulted in decreased recoverability on laboratory media, due possibly to an increased metabolic rate, as analyzed by CO2 evolution in the presence of radiolabeled glutamate.

Validity of the Indicator Organism Paradigm for Pathogen Reduction in Reclaimed Water and Public Health Protection
Valerie J. Harwood,Audrey D. Levine,Troy M. Scott,Vasanta Chivukula,Jerzy Lukasik,Samuel R. Farrah,Joan B. Rose +6 more
TL;DR: Monitoring a suite of indicator organisms in reclaimed effluent is more likely to be predictive of the presence of certain pathogens, and a need for additional pathogen monitoring in reclaimed water in order to protect public health is suggested by this study.

Campylobacters in water, sewage and the environment.
TL;DR: The marked seasonal pattern of campylobacters in temperate, aquatic environments is a result of variations in Campylobacter die-off rates at different times of the year.
