Summary: Experimental manipulation of protozoan predation pressure in activated sludge communities had strong and positive effects on bacterial diversity components, with responses leveling off at higher predation pressure levels. While predator intensity positively impacted taxa richness, predator diversity had mixed effects on bacterial diversity. Reduction in top-down control by predators negatively affected taxa associated with treatment efficiency, particularly nitrogen removal. The study highlights distinct mechanisms linking protozoan predation with bacterial diversity and community composition in activated sludge communities.

Summary: Partial nitritation was identified as a key step in autotrophic nitrogen removal processes at low temperatures. This study successfully maintained a nitritation process with simultaneous COD removal in a sequencing batch reactor operated at 15 degrees C. Despite fluctuations in municipal wastewater composition, a high nitrite accumulation ratio was observed, and the presence of nitrite oxidizing bacteria (NOB) was attributed to high levels of free nitrous acid (FNA) in the system.

Summary: Soil microorganisms play a crucial role in maintaining soil functions and services, but our understanding of their spatial-temporal dynamics is still limited. This study analyzes the temporal trends in soil microbial biomass carbon and identifies the main drivers of change, revealing the areas sensitive to environmental factors. The research finds that global soil microbial biomass carbon has decreased by approximately 3.4% over the past 20 years, with increasing temperatures being the main driver of decline in the northern regions.

Summary: Excessive nitrogen fertilizer usage in agriculture has negative effects on ecological and production gains. This study investigated the impact of different nitrogen levels on soil properties and microorganisms in agricultural soils. Moderate reduction in nitrogen did not lead to significant yield loss due to increased nitrogen use efficiency, attributed to available phosphorus and potassium.

Summary: Despite limited research on Ericoid mycorrhizal fungi, this study isolated and identified 14 endomycorrhizal fungi, with six strains confirmed to be beneficial for blueberry plants. The study showed that after the formation of ERM, nitrogen and phosphorous content in blueberry seedlings significantly increased, influencing growth and development. Additionally, cloning and overexpression of specific genes in transgenic plants enriched total phosphorus and chlorophyll content, emphasizing the importance of these genes in phosphorus transport and absorption.

Summary: The study found that one-time tillage had minimal impact on soil microbiome richness and diversity, but significantly affected the abundance of certain microbial taxa associated with carbon degradation. Stubble retention was the main factor contributing to increased richness and diversity of soil bacterial and fungal communities. Supplementary fertilizer application had minimal impact on bacterial and fungal richness and diversity.

Summary: Soil degradation is a complex process that affects crop production and the environment. In Chinese rice fields, soil nitrogen, phosphorus, and available-P concentrations were found to decline with increasing soil degradation, while environmental factors like humidity and temperature also influenced soil organic matter and degradation levels. Restricting annual cropping frequencies and adopting sustainable farming practices can help prevent further soil degradation in China.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
