Summary: This study investigated the community composition, diversity, and abundance of Methanoperedens-like archaea in a freshwater wetland. The results showed significant differences in community composition among different sampling sites, and the abundance of these archaea was positively correlated with soil water content. The mcrA gene was identified as a good biomarker for the detection and quantification of Methanoperedens-like archaea.

Summary: This study aimed to assess and validate a protocol for optimizing the identification and quantification of polyethylene microplastics (PE MPs) in biological samples. The use of acetonitrile for digestion of cellulosic membranes was found to prevent loss of particles and promote good dispersion of MPs. Neubauer chambers showed good recovery rates and consistent results for quantifying MPs in samples with different concentrations.

Summary: Microbial rhodopsins are widely distributed in aquatic environments and may significantly contribute to phototrophy and energy budgets in global oceans. The study explored the diversity, distribution, and expression of opsin genes in freshwater lakes with different characteristics. The results showed that opsin genes occurred more frequently in clearwater lakes, and their distribution was influenced by lake optical properties and dissolved organic carbon (DOC) levels. Gene expression analysis confirmed the significance of rhodopsin-based phototrophy in clearwater lakes. Overall, these findings highlight the importance of rhodopsin-based phototrophy in freshwater energy budgets.

Summary: Many European lakes have experienced reed die-back since the 1950s, possibly due to a single threat with high impact such as increased sulphate concentrations. A comprehensive study on 14 lakes in the Berlin area revealed a strong negative relationship between reed ratio and sulphate concentrations, as well as tree shading, and a strong positive relationship with brushwood fascines. Changes in water quality upstream should be considered in the management plans for downstream lakes.

Summary: Harmful algal blooms, especially cyanobacterial blooms, are occurring in many freshwater lakes worldwide, impacting public health and ecosystem integrity. To mitigate their negative effects, prediction, early detection, and monitoring of algal blooms are crucial. Remote sensing, including different platforms and AI-based algorithms, provides an effective and cost-efficient method for detecting and monitoring these events. Recent advancements in using UAV platforms equipped with sophisticated sensors have revolutionized the detection and monitoring of water quality. Predicting algal blooms based on AI methods will play a key role in mitigating eutrophication in the future.

Summary: This study reviews the main indicators of eutrophication in global freshwater lake basins, which include not only water quality constituents but also the sources, biogeochemical pathways, and responses of nutrient emissions. The authors propose a new causal network framework that highlights complex interrelationships among the indicators and provides a holistic perspective of eutrophication dynamics in freshwater lake basins. The study indicates a need for more comprehensive indicators to guide the global expansion of water quality monitoring networks and support integrated assessments to manage eutrophication.

Summary: The study demonstrates that SARS-CoV-2 RNA levels in wastewater generally corresponded with the number of clinical cases in large urban centers, decreasing significantly after lockdown measures were implemented. Genetic sequencing of the virus in wastewater revealed multiple distinct clusters circulating in the local population, reflecting similarities with SNPs found in clinical samples. The findings suggest that wastewater-based epidemiology can be a valuable tool for monitoring and tracking the prevalence of SARS-CoV-2 and other viruses in the community, aiding in public health policy decisions.

Summary: Long-term carbon deprivation in soils led to reduced diversity measures, particularly impacting fungi. Functional gene copies also decreased after 10 years, although some related to decomposing recalcitrant carbon and methanogenesis increased. Unexpectedly, pore connectivity increased after 10 years of carbon deprivation.

Summary: Wastewater-based epidemiology (WBE) is a useful tool in monitoring SARS-CoV-2 during the pandemic. This study compared three viral concentration methods and found that there was no major difference in viral recovery using these methods. However, factors such as sample turbidity, storage temperature, and surfactant load did affect viral recovery, emphasizing the importance of considering these factors when working with wastewater samples.

Summary: This study compared the rhizosphere microbiomes of two sugarcane varieties, one drought-resistant and the other drought-sensitive, under normal and water-limiting conditions. The results showed that certain bacteria in the drought-resistant variety exhibited increased activity in terms of mobility, colonization, and cell growth, while the drought-sensitive variety showed changes in bacterial composition and DNA metabolism. These findings suggest that plant genotype regulates the variation in rhizosphere microbiota and identifies potential beneficial bacteria for plants under water scarcity.

Summary: Pesticides have both positive and negative impacts on the agriculture and environmental sectors. It is important for the scientific community and policymakers to actively find solutions to mitigate environmental contamination caused by over-reliance on pesticides. This study provides a comprehensive analysis of microbial systems capable of dissipating pesticides from agricultural soils based on the academic literature from 2018 to 2021. Introducing specific microorganisms into the system can enhance the biodegradation process and improve cost-effectiveness.

Summary: In this study, the adsorption mechanism of phage LP31 was investigated, which not only improves the precision and efficiency of phage therapy but also opens up possibilities for other potential applications and modifications of phages. By constructing a knockout strain C50041 Delta rfaL(58-358), researchers discovered that the knockout strain exhibited a rough phenotype due to the deficiency of O-antigen. The results showed that the receptor for phage LP31 was the O-9 antigen of S. Enteritidis, and the tail fiber protein Lp35 of phage LP31 participated in the adsorption process as a receptor-binding protein.
