Summary: Bacterial regrowth after water/wastewater disinfection poses serious risks to public health. This study assessed the regrowth of E. coli in environmental waters after chlorine disinfection, and found that chlorine treatment induced a majority of E. coli to enter a viable but non-culturable state. A second-order regrowth model accurately described the temporal shift of the survival ratio of culturable E. coli. The study highlights the need to investigate the detailed relation of regrowth to environmental conditions.

Summary: This study explored the dynamics of soil organic carbon (SOC) stock in response to experimental phosphorus (P) additions. The results showed that P additions significantly increased SOC stock globally, with the effect depending on soil nitrogen (N) availability. Under high N availability, P additions mainly increased plant biomass and litterfall, while under low N availability, P additions not only increased plant biomass and litterfall, but also soil microbial biomass and oxidase activity. However, the increases in aboveground biomass and litterfall did not lead to corresponding carbon accumulation in the soil, possibly due to microbial CO2 release. Reactive N input reduced P-addition-induced carbon loss and enhanced the effect of P additions on SOC.

Summary: The mechanisms by which microplastics affect soil microbes and their metagenomic functioning are currently uncertain. In this study, we investigated the response mechanisms of bacterial and fungal communities to the addition of PVC microplastics in two soils with different pH and heavy metal levels. The results showed that PVC microplastics increased soil pH and reduced heavy metal availability, while also reducing bacterial diversity and interaction networks. Our study suggests that the addition of PVC microplastics could shift soil microbial community and metagenomic functioning.

Summary: This study found that aerated drip irrigation (ADI) can increase fungal community diversity but has no significant effect on bacterial community diversity. ADI treatments can increase bacterial phylum Gemmatimonadetes and Firmicutes, as well as enrich the fungal phylum Mortierellomycota and phosphorus-dissolving taxa. ADI treatments can also enhance functional groups related to carbon and phosphorus cycling while decreasing Plant Pathogen functional groups.

Summary: Phosphorus (P) is a vital macronutrient for all life on Earth and plays a crucial role in plant growth and yield. However, P deficiency is a common problem in terrestrial ecosystems worldwide. The use of chemical phosphate fertilizer has limitations due to its non-renewable raw materials and adverse effects on the environment. Therefore, finding alternative strategies, such as phosphate-solubilizing bacteria (PSB), to meet plant P demand is important. This article reviews the biogeochemical P cycling in soil systems, explores the use of PSB to alleviate global P resource shortage, discusses the advances in multi-omics technologies, and analyzes the multiple roles of PSB inoculants in sustainable agricultural practices. The authors propose that further research is needed to better understand the interactive mechanisms between PSB, rhizosphere microbiota, and plants in order to maximize the efficacy of PSB as P activators.

Summary: VBNC bacteria are attracting attention as they cannot be detected by traditional culture-dependent methods and can resuscitate under favorable conditions. This study detected significant quantities of viable/VBNC opportunistic pathogens in full-scale DWTPs, indicating the inadequacy of traditional methods in detecting these bacteria. Development of rapid, accurate methods for detection of VBNC pathogenic bacteria in DWTPs is necessary to ensure drinking water safety.

Summary: The H-02 constructed wetland was designed to remove metals (primarily copper and zinc) from building process water and storm water runoff. However, the concentration of copper and zinc in the wetland sediments has increased over time. A newly isolated bacterium of the copper metabolizing genus Cupriavidus, Cupriavidus basilensis SRS, was investigated for its potential to bioremediate sites impacted with heavy metals, particularly copper. The research demonstrated significant decrease in copper concentrations and variability in zinc concentrations when wetland samples were inoculated with Cupriavidus basilensis SRS.

Summary: The study reveals that ectomycorrhizal fungi with peroxidases decrease with increasing inorganic nitrogen availability in northern temperate forests, while ligninolytic fungal saprotrophs show no response. Soil organic matter and soil carbon are negatively correlated with ECM fungi with peroxidases and positively correlated with inorganic nitrogen availability, indicating that these ECM fungi contribute to the decay of lignin-derived soil organic matter and reduce soil carbon storage. The correlations observed suggest a tradeoff between tree nitrogen nutrition and ECM composition, influencing soil organic matter dynamics in temperate forests.

Summary: Soil microorganisms play a key role in soil biochemical processes, but their resilience after extreme environmental change is largely unknown. This study investigated the structural and functional responses of microbial communities during recolonization of heat-sterilized forest soils. The results showed rapid changes in enzymatic activity, microbial structure, and catabolic activity during the incubation period. The physicochemical properties of the original soils influenced soil functional diversity, and reinoculation of sterilized soils had a greater impact on bacterial communities than fungal communities.

Summary: Biochar production and incorporation into soil is seen as a sustainable strategy for climate change mitigation. There is emerging evidence that biochar induces carbon sequestration in soil through complex microbial processes and an increase in carbon use efficiency. The current paradigm of decreased microbial carbon use efficiency during the degradation of recalcitrant material is contradicted by this evidence. This paper examines the link between biochar properties, soil physico-chemical properties, and microbial physiology to explain the increase in carbon use efficiency in biochar-amended soils.

Summary: Soil microbial community coalescence, the mixing and interaction of microbial communities, has been found to enhance the stability and complexity of rhizobacterial networks, leading to improved plant health and biomass. This study investigated the effects of different degrees of bacterial community coalescence on plant disease resistance by mixing soils from healthy and diseased habitats for watermelon planting. The results showed that mixing in more healthy soil reduced the plant disease index and increased biomass by improving the stability and complexity of the rhizobacterial network. Core taxa Nitrospirillum and Singulisphaera were enriched in the rhizosphere from healthy soils and played important roles in disease suppression and regulating the positive cohesion and modularity of the networks. Overall, these findings provide insights into the potential mechanism of microbial community coalescence for improving plant microbial community function and suggest new tools for enhancing plant fitness via soil microbiota mixing.

Summary: Collembolans, the diverse group of soil invertebrates, are affected by anthropogenic climate warming, which alters their diversity and density. In addition to abiotic stressors, changes in food availability, specifically the abundance of saprotrophic and mycorrhizal fungi, influence Collembola responses to climate warming. Collembolans prefer saprotrophic fungi but rely on mycorrhizal fungi when food sources are scarce. Understanding the mechanisms behind these dietary shifts in warm-dry and warm-wet soil conditions is crucial for predicting the impact of climate change on Collembola-fungal interactions.
