Summary: Microbial water quality is a major concern worldwide, and this study aimed to evaluate the microbiological quality of drinking water on dairy cattle farms in Portugal. The study found that 59.4% of the cattle farms had poor water quality, and identified bacterial species such as Escherichia coli and Enterococcus faecalis. It was also found that farms that did not routinely perform disinfection had the worst water quality. This research highlights the importance of screening drinking water quality on cattle farms for improved health outcomes in both animals and humans.

Summary: Improving microbial quality of agricultural water through ZVI-sand filtration is effective in reducing E. coli levels. The study found that the composition of ZVI in sand filters and influent water type impact the effectiveness of E. coli reduction. In waters with low turbidity values, ZVI-sand filtration showed more effective reduction of E. coli levels.

Summary: Urban coastal water quality in Ghana is impacted by agricultural runoff, sewage discharges, and poor sanitation, leading to high levels of bacteria, particularly faecal indicator bacteria. The study showed no significant variation in environmental parameters, but significant differences in bacteria loads among beaches, influenced by nitrate and total dissolved solids. This calls for public awareness and policy reforms to control coastal water pollution and further research on contamination sources in the tropical Atlantic region.

Summary: This paper proposes using mechanistic modeling to improve strategies for mitigating the risk of pathogenic bacteria spreading through pond irrigation water to fresh produce. Global sensitivity analysis quantified important processes driving pond bacterial contamination events, highlighting the need for temporal management strategies in preventing bacterial contamination of surface water irrigation ponds.

Summary: Efficient removal of impurities via filtration is crucial in biopharmaceutical production. We investigated the impact of host cell-derived impurities on the performance of sterile filters, focusing on the decrease in filter capacity induced by dsDNA. Our findings revealed that dsDNA has a major influence on rapid membrane fouling, particularly in filters with small pore sizes (<0.2 μm). By reducing the size of dsDNA fragments or decreasing the electrostatic interactions with positively charged molecules, filter capacity can be significantly increased. Overall, our study emphasizes the importance of monitoring dsDNA even during the primary recovery of proteins in cell lysates.

Summary: This study assessed the water quality of four important tributaries of the Tigris River in the Bismil Plain, Turkey. Most parameters in the water samples were below drinking water limits, except for Kuru ay Stream which had higher levels of certain contaminants due to sewage and agricultural runoff. The water type in all streams was dominated by Ca-HCO3, and rock weathering was found to be the major factor affecting stream hydrochemistry. Overall, the water quality was good for drinking and irrigation purposes, except for one station in Kuru ay Stream which had poor quality water. The findings also showed that the water quality of Kurucay Stream was worse due to receiving large amounts of irrigation return flows compared to other streams.

Summary: This research analyzed the structure of a microorganism group in sediment and the absolute abundance of two typical pathogenic bacteria in Shahe Reservoir, China. The results show a positive correlation between the abundance of pathogenic bacteria and water eutrophication in the reservoir sediment. Additionally, the distribution of the pathogenic bacteria varies with depth and location in the sediment.

Summary: Detection of bacteria in water is crucial for determining their use and preventing environmental and health issues. This study presents a portable electronic monitoring system based on colorimetric measurements, which speeds up the detection of bacteria compared to conventional techniques. The system enhances the threshold of detection and automates the sampling process, reducing waiting and processing time by over 60%.

Summary: Recent E. coli O157:H7 outbreaks in Alberta, Canada, have been linked to contaminated pork, and this study found that pigs can be a significant source of the organism due to some strains establishing persistence on pig farms. Whole-genome analysis confirmed the close connection between isolates from pigs, cattle, and pork-production environments, with environmental isolates being more closely related to pig isolates. The majority of pig isolates harbored only one Shiga toxin gene, while a high percentage of cattle isolates had both stx(1a) and stx(2a) genes.

Summary: The optimal allocation of agricultural water and land resources is crucial for farmers' economic benefits, carbon sequestration, and water resource conservation. This study developed a novel water-carbon-economy coupling model and applied it to a real farm, demonstrating its effectiveness in achieving the optimal allocation of water and land resources. The model balances economic, environmental, and social benefits.
