Summary: Reclaimed water is increasingly used to address the water resource crisis caused by accelerated urbanization worldwide. Although it enriches aquatic ecosystems with organic matter, nitrogen, and phosphorus, its impact on the self-purification capacity of receiving waters remains poorly understood. This study evaluated the effects of reclaimed water use on water quality, sedimentary bacterial diversity, community structure, and function. The results showed that reclaimed water improved water quality, increased bacterial abundance, and enhanced the carbon, nitrogen, and phosphorus removal functions of polluted waters. These findings contribute to a better understanding of the ecological impact of reclaimed water on urban aquatic ecosystems and inform the rational use of reclaimed water in urban rivers.

Summary: This study analyzed the environmental quality of canals in the Po plain, including vegetation diversity, water quality, and bed sediment characteristics, and investigated how these features are influenced by canal management and surrounding landscape. The results showed that low water flow during certain periods worsened water quality, and canals crossing areas with fine texture alluvial deposits had higher salt and nutrient concentrations. However, vegetation type and biodiversity were mainly affected by the land use of the surrounding landscape, rather than canal management and environmental characteristics.

Summary: Reclaimed water reuse is a promising strategy for addressing water scarcity, but its potential ecological impact remains largely unknown. This study aimed to elucidate the distinct effects of reclaimed water on bacterioplankton and bacteriobenthos communities in reclaimed water-receiving river networks. Significant differences in microbial composition were observed between the plankton and benthic habitats, and the association between wastewater treatment plants (WWTP) and benthic habitats was stronger. The study also revealed the biomarker and key module hub for bacterioplankton and bacteriobenthos communities, and highlighted the importance of nitrogen as a pollutant affecting the structure and ecological functions of microbial communities.

Summary: The colonization of mussels can impact water quality by altering nearby bacterial communities. A study using high-throughput sequencing revealed that bacterial assemblages associated with live and dead mussels consume nutrients and tissues, leading to poor water quality and reduced bacterial alpha-diversity, especially in dead mussel groups. The dissimilarity of bacterial communities between live and dead mussel groups was more significant than that between different initial water qualities, emphasizing the dominance of mussel colonization and living status on bacterial communities.

Summary: The rhizosphere bacterial communities in low fertility soil are influenced by rice genotype and nitrogen fertilization. In this study, it was found that genotype was the primary factor affecting the diversity of rhizobacteria, followed by nitrogen fertilizer rate. The rhizobacteria diversity was higher in the japonica/indica hybrid rice than in the japonica conventional rice, and it did not significantly change overall with increasing nitrogen fertilizer rates. The response to nitrogen fertilizer rates differed between the two genotypes and was likely due to differences in ammonium and/or nitrate levels in the rhizosphere.

Summary: By using high-throughput sequencing and molecular ecological network methods, this study compared the effects of different remediation tree species on soil bacterial communities and provided a theoretical basis for selecting ecosystem function promotion strategies after vegetation restoration. The results showed that the reclaimed soil properties became closer to the control group as the reclamation years increased, with Pinus tabulaeformis having properties closer to the control group than Populus euramericana. The dominant bacteria in the restored soil were Proteobacteria, Actinobacteria, Acidobacteria, Chloroflexi, Gemmatimonadetes, Planctomycetes, Bacteroidetes, and Cyanobacteria, and the bacterial community diversity and abundance were higher in the P. euramericana reclaimed soil than in the P. tabulaeformis reclaimed soil. The ecological network analysis indicated that the bacterial network under P. euramericana reclamation was more abundant than under P. tabulaeformis reclamation.

Summary: Studies based on protein-coding genes are crucial for understanding the diversity within bacterial functional groups. This study focuses on the pufM gene, a genetic marker for aerobic anoxygenic phototrophic (AAP) bacteria, and evaluates existing primers for its amplification, designs new ones, and assesses their phylogenetic coverage. The results reveal biases in commonly used PCR primers towards specific bacterial phyla, and the metagenomic approach provides a more accurate representation of the abundance and diversity of AAP bacteria. The framework developed in this study can serve as a reference for primer evaluation of other functional genes.

Summary: In this study, 338 microorganisms were isolated from sediment samples collected from underexplored regions of Colombia. Screening trials were conducted to evaluate their tolerance to heavy metals, leading to the identification of several bacteria capable of withstanding high concentrations of cadmium, lead, and zinc. Further experiments revealed that one particular strain of Pseudomonas showed significant potential for lead removal. Infrared spectroscopy analysis suggested interactions between the metal and functional groups in the biomass. These findings highlight the potential of microorganisms from coastal marine environments for bioremediation of heavy metal-polluted environments.

Summary: Traditional culture techniques often underestimate the diversity of marine microbial communities, particularly in the deep ocean. In this study, we compared cultured heterotrophic bacteria with globally collected 16S rRNA metabarcoding datasets to assess the recovery of bacterial communities at different ocean depths. Our results indicate a higher proportion of isolates matching the metabarcoding data in the deep ocean, suggesting that sinking particles in the bathypelagic zone serve as nutrient-rich habitats for cultivable heterotrophic bacteria. These bacteria contribute to prokaryotic communities across different plankton size fractions, functioning as both free-living and particle-associated organisms.
