Taihu Lake is the third largest freshwater lake in China and serves as a drinking water source for ~30 million residents. Tiaoxi River one of main rivers connected to this contributes >60% water. has been facing various environmental issues; therefore, it important study quality its inflow rivers. This aimed evaluate physico-chemical microbiological characteristics determine spatial seasonal variations quality. Water samples were collected from 25 locations across three seasons 2014–2015....

Taihu Lake is one of the largest freshwater lakes in China, serving as an important source drinking water; >60% water to this lake provided by Tiaoxi River. This river faces serious fecal contamination issues, and therefore, a comprehensive investigation identify sources was carried out presented here. The performance existing universal (BacUni GenBac), human (HF183-Taqman, HF183-SYBR, BacHum, Hum2), swine (Pig-2-Bac), ruminant (BacCow), avian (AV4143 GFD) associated microbial tracking (MST)...

Urbanization is increasing worldwide and happening at a rapid rate in China line with economic development. can lead to major changes freshwater environments through multiple chemical microbial contaminants. We assessed the impact of urbanization on physicochemical characteristics loading canals Suzhou, city that has experienced recent decades. Nine sampling locations covering three urban intensity classes (high, medium low) Suzhou were selected for field studies Huangshan (natural reserve)...

The purpose of this study was to conduct a correlative assessment SARS-CoV-2 RNA concentrations in wastewater with COVID-19 cases and systematic evaluation the effect using different virus concentration methods recovery normalization approaches. We measured at two treatment plants (WWTPs) Bexar County Texas from October 2020 May 2021 (32 weeks) reverse transcription droplet digital PCR (RT-ddPCR). evaluated three adsorption–extraction (AE) based (acidification, addition MgCl2, or without any...

This study contributes to the collective evaluation of SARS-CoV-2 RNA persistence and removal along wastewater treatment stages a plant in San Antonio, Texas.

Hurricanes and extreme stormwater events can transport fecal contaminants a wide range of bacterial pathogens to receiving rivers streams, threatening public health. This study investigated the impact flooding on diversity occurrence potential in Texas Rivers over short (3 weeks 3 months) long time (12 after Hurricane Harvey. Water samples were collected from 8 sampling sites Guadalupe San Antonio during three community structure was evaluated using next-generation sequencing (NGS). Results...

Abstract Freshwater environments are vulnerable to emerging contaminants such as Antibiotic resistance genes (ARGs), and their occurrence is gaining more attention. However, the of ARGs along with potential pathogens less explored. The current study aimed evaluate abundance explore bacterial communities for presence in water samples collected from a tributary Yangtze River Nanjing. Twelve physico-chemical parameters were analyzed, followed by quantifying 10 targeting sulfonamide ( sul1, sul2...

Stormwater detention basins serve as vital components in mitigating the adverse effects of urban runoff, and investigating microbial dynamics within these systems is crucial for enhancing their performance pollutant removal capabilities. The aim this study was to examine compare soil bacterial communities two stormwater located on Edwards Aquifer Bexar County, Texas, USA, evaluate how physiochemical properties may affect them.Each basin sampled different seasons at varying depths structure...

This study investigated the sources of fecal pollution in surface and groundwaters collected from three urban watersheds Texas during dry wet weather identified impact precipitation on water quality. Water samples (n = 316 107 for events, respectively) were biweekly eight sampling sites (6 creeks ponds, 2 well sites) two-year monitoring analyzed six physico-chemical parameters ten qPCR-based assays targeting general ( E . coli , Enterococcus universal Bacteroidales ), human (BacHum HF183),...

Fecal pollution of surface waters in the karst-dominated Edwards aquifer is a serious concern as contaminated can rapidly transmit to groundwaters, which are used for domestic purposes. Although microbial source tracking (MST) detects sources fecal pollution, integrating data related environmental processes (precipitation) and land management practices (septic tanks) with MST provide better understanding contamination fluxes implement effective mitigation strategies. Here, we investigated...

Differently expressed proteins in probiotic Escherichia coli nissle 1917 under mercury stress identified by using a proteomic approach.We applied to separate two-dimensional gel electrophoresis and were MALDI-TOF-MS PMF, mascot database search the NCBI database.we six after exposure with respect different functional classes.It is useful understand molecular insights into E. coli.Next we describe structure generated homology modelling domain identification; it interesting study impact of on...

Praecitrullus fistulous is a herbaceous annual plant in the Cucurbitaceae, native to India, and distributed widely tropics warmer temperate regions. It also known as Indian baby pumpkin, round gourd, apple gourd or tinda, mostly cultivated vegetable. In P. fistulosus extensively grown for local international export markets. From 2009 2010, severe fruit rot was observed on Hyderabad, Mahaboob Nagar Ranga Reddy districts, Andhra Pradesh, India. All fields were late harvesting stage. The most...
