Summary: A heterotrophic nitrifier and aerobic denitrifier, identified as Enterobacter cloacae DK-6, was isolated from chaff bedding of a pig farm. Strain DK-6 showed efficient nitrogen removal abilities under aerobic condition, achieving removal efficiencies of 86.98%, 94.66%, and 100% for ammonium-N, nitrate-N, and nitrite-N, respectively. The study also found that strain DK-6 preferred to utilize nitrite-N when mixed nitrogen sources were present, leading to improved nitrate-N removal efficiency. The results suggested that strain DK-6 has significant potential in treating multiple nitrogen pollutants in wastewater under aerobic condition and lower carbon/nitrogen ratio.

Summary: Artificial intervention and stress acclimation were used to screen a bacterial strain Rhodococcus SY24 that is resistant to linear alkylbenzenesulfonic acid (LAS) stress. Strain SY24 showed better cell growth and carbon source metabolism activity at LAS concentrations below 15 mg/L. It exhibited higher nitrification and denitrification rates under LAS stress compared to the original strain CPZ24. Functional genes analysis revealed higher LAS tolerance in strain SY24. A response surface model identified the ideal culture conditions for strain SY24 to achieve nitrogen removal under LAS stress. This study provides a new screening strategy for functional species and highlights the LAS tolerance and HN-AD potential of strain SY24.

Summary: Dissolved carbon dioxide (CO2) in seawater can disrupt microbial nutrient cycles, impacting hot spots of nutrient cycling such as eelgrass (Zostera marina) beds. Acidification increases denitrification dominance and decreases nitrogen (N) fixation. Under acidified conditions with nitrogen-enriched treatments, eelgrass beds may serve as sinks rather than sources of N.

Summary: This study investigates denitrification performance, metabolic patterns, and ecological structure in parallel well-controlled bioreactors fed with four representative carbon sources. The results show that different carbon sources induce the succession of denitrifying microbiota towards different ecological structures and exhibit distinct metabolic patterns. Methanol-fed reactors show unique microbial carbon utilization pathways and a more intricate microbial interaction network, leading to significant variations in organic utilization and metabolite production compared to other carbon sources.

Summary: Anaerobic digestion (AD) is an efficient technology that converts organic waste into biofuel. This study investigated the mitigation effect of a metal-organic framework (MOF)-derived nanocomposite (FeMn-MOF/G) on ammonia nitrogen inhibition in AD. The results showed that FeMn-MOF/G had an average ammonia nitrogen adsorption capacity of 102.68 mg/g in AD, and its adsorption effect decreased with increasing solids concentration. The addition of FeMn-MOF/G effectively reduced ammonia nitrogen and VFAs concentration, and increased methane production in AD.

Summary: In this study, the effects of cadmium stress on the root tissues of Pistia stratiotes were investigated using untargeted metabolomics and RNA-Seq sequencing. The results showed that cadmium stress affected the accumulation and transport of cadmium in plants, altered the activities of several enzymes, and decreased the contents of carotenoids and chlorophylls, thus impacting plant growth and development. Metabolomic analysis revealed the impact of cadmium stress on various metabolic pathways, while transcriptome analysis identified differentially expressed genes involved in key metabolic pathways. This study provides valuable insights into the response mechanisms of P. stratiotes to cadmium stress and contributes to the theoretical basis for phytoremediation of cadmium-contaminated water.

Summary: The abundance and characteristics of microplastics (MPs) in surface water and sediment samples from the Wanquan River estuary were investigated. The results showed high abundance of MPs in the estuary, mostly red fragments smaller than 1.0 mm, predominantly composed of antifouling paint particles (APPs). The study also found a significant positive correlation between the concentration of Cu2+ and the abundance of APPs in the sediment samples. This study expands our knowledge about MP pollution in small estuaries and highlights the ecological risk of APPs in the Wanquan River estuary to aquatic organisms.

Summary: Alkaline fermentation can produce sludge alkaline fermentation liquid (SAFL) rich in short-chain fatty acids (SCFAs), which can be used as a high-quality carbon source for the biological nutrient removal (BNR) process. SAFL has advantages of higher efficiency and economy compared to traditional carbon sources, and different operating conditions affect the yield and structure of SCFAs in SAFL. SAFL significantly improves the nutrient removal efficiency of the BNR process and can solve the problems of carbon source shortage and sludge treatment difficulties in wastewater treatment plants.

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.

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.
