Microbial communities are an important component of aquatic ecosystems. They play active roles in the biogeochemical cycles organic matter and nutrients to maintain health stability In present study, shifts microbial overlying water 15 shallow lakes with different trophic states Hubei Province (China) were assessed using Illumina MiSeq sequencing technology. The results revealed that proteobacteria be most abundant phylum states. Mesotrophic found similar moderately eutrophic terms community composition, interrelation between communities, expression level metabolic pathways. mesotrophic lakes, Bacillus Pseudomonas dominant genera water. less eutrophication, diversity tended higher. Lightly had species; however, interaction microorganisms was weakest these internal steady-state balance susceptible being broken. These indicate lightly eutrophication may one unstable transition process.

Species-specific functional trait responses of canopy-forming and rosette-forming macrophytes to nitrogen loading: Implications for water–sediment interactions

Environment International, Journal Year: 2024, Volume and Issue: 185, P. 108557 - 108557

Published: March 1, 2024

Globally intensified lake eutrophication, attributed to excessive anthropogenic nitrogen loading, emerges as a significant driver of submerged vegetation degradation. Consequently, the impact on decline macrophytes has received increasing attention. However, functional trait-based approach exploring response loading and its environmental feedback mechanism was unclear. Our study utilized two different growth forms (canopy-forming Myriophyllum spicatum, rosette-forming Vallisneria natans) established "submerged macrophytes-water–sediment" microcosms. We assessed influence across four targeted total concentrations (original control, 2, 5, 10 mg/L), plant traits, water parameters, sediment properties, enzyme activities, microbial characteristics. findings revealed that high (10 mg/L) adversely impacted relative rate fresh biomass chlorophyll content in canopy-forming M. while a/b free amino acid increased. On contrary, photosynthetic traits resource-conservative V. natans were not affected by loading. Functional (growth, photosynthetic, stoichiometric) spicatum but exhibited correlations with variables. Nitrogen significantly increased concentration components overlying pore water. The presence reduced ammonia both water, decreased organic carbon inhibited extracellular planting mitigated their negative effects. Furthermore, rhizosphere bacterial interactions less compact compared bare eukaryotic communities complexity connectivity. Path modeling indicated direct effects amplified indirect also attenuating enzymes. restoration can mitigate eutrophication resulting from through species-specific changes or mechanisms water–sediment system.

Spread of antibiotic resistance genes in drinking water reservoirs: Insights from a deep metagenomic study using a curated database

Water Research, Journal Year: 2024, Volume and Issue: 256, P. 121572 - 121572

Published: April 4, 2024

The exploration of antibiotic resistance genes (ARGs) in drinking water reservoirs is an emerging field. Using a curated database, we enhanced the ARG detection and conducted comprehensive analysis using 2.2 Tb deep metagenomic sequencing data to determine distribution ARGs across 16 associated environments. Our findings reveal greater diversity sediments than water, underscoring importance extensive background surveys. Crucial carriers—specifically Acinetobacter, Pseudomonas, Mycobacterium were identified reservoirs. Extensive uncovered considerable concern for safety, particularly regions reliant on river sources. Mobile genetic elements have been found contribute markedly propagation ARGs. results this research suggest that establishment supplying raw may be effective strategy alleviating spread water-mediated
