Summary: This study found that elevated atmospheric carbon dioxide (eCO2) has a significant impact on water fluxes, leading to a decrease in evapotranspiration and an increase in seepage. The increase in stomatal resistance was identified as the primary influence of eCO2 on evapotranspiration. Neglecting the effect of eCO2 in assessments of climate change on grassland water fluxes may result in overestimation of transpiration and underestimation of seepage.

Summary: Nitrate leaching is a significant environmental concern, especially for potatoes grown on sandy soils. This study found that under irrigation, the use of PCU reduced NO3--N leaching compared to PCU + urea, but both increased leaching compared to the conventional fertilizer mixture. Despite lower plant N uptake, PCU resulted in greater yields compared to PCU + urea, showing that the efficiency of PCU in reducing NO3--N leaching may vary depending on precipitation and irrigation timing.

Summary: This study found that after the application of beef cattle manure, the attachment of ARGs in the soil was significantly higher in the treatment column than in the control column. However, the detachment and decay coefficients were not significantly changed due to manure application. These results suggest that in areas where manure is applied, some manure-borne bacteria-associated ARGs will be attached to the soil instead of leaching to groundwater in the near term.

Summary: An increasing number of studies have shown that the assumption that rock fragments are inert with respect to water retention is incorrect, highlighting a gap in research. By developing new pedotransfer functions based on measurements from stony soils in New Zealand, it was possible to accurately predict the water content of these soils, demonstrating the importance of considering rock fragments in water retention models. The existing model, which did not account for the effects of rock fragments, performed poorly compared to the new models, indicating the need for more comprehensive models in soil water retention studies.

Summary: This study investigates the effect of cation exchange resin (CER) on the sequential recovery of hydrogen and methane from anaerobic digestion (AD) and the corresponding mechanisms. The results show that CER can simultaneously enhance the production of hydrogen and methane by promoting the solubilisation, hydrolysis, and acidification of organic matter. Additionally, CER facilitates effective contact between bacteria and organic particulates and reduces the energy barrier for mass transfer during methane production. The study also reveals changes in the microbial community structure and metagenomics during the AD process.

Summary: The fouling of seawater reverse osmosis membranes is a persistent challenge in desalination. This study monitored the operational performance of a desalination plant for 7 years and the fouling development in different areas of membrane modules. The findings showed that operational performance declined over time and fouling mainly occurred at the feed side of the modules, with the highest microbial diversity. Keystone species like Chloroflexi and Planctomycetes played an important role in maintaining community structure and biofilm maturation. Polysaccharides, soluble microbial products, marine humic acid-like substances, and inorganic substances contributed to fouling. Overall, biofouling had a significant impact on membrane fouling after 7 years of operation.

Summary: This study implemented a microaerobic-aerobic configuration in a full-scale municipal wastewater treatment facility and investigated the effects on sludge characteristics, pollutant removal, microbial community, and granulation mechanisms. The results showed successful transition from flocculent-activated sludge to well-defined AGS after two months of operation. The primary pathways for pollutant removal were simultaneous nitrification, denitrification, and phosphorus removal. Moreover, the incorporation of internal separators induced shifts in the flow pattern, which promoted granulation.

Summary: By synergizing organic carbon source, thiosulfate, and zero-valent iron, efficient mixotrophic denitrification of oligotrophic secondary effluent can be achieved. Thiosulfate plays a vital role in promoting TN removal efficiency, while corrosion of Fe0 releases OH- to neutralize H+ from thiosulfate-driven denitrification, creating a suitable environment for denitrification. The coordination of thiosulfate and Fe0 maintains the dominance of Thiobacillus for denitrification.
