Summary: The meta-analysis of laboratory incubation studies with 1-octyne as the nitrification inhibitor shows that AOB play a more dominant role in soil nitrification in cropland than in wetland soils, indicating a major role of AOB in acidic soil nitrification. Moreover, the reduction of nitrification rate by 1-octyne is greater in soils incubated in slurry and with nitrogen additions, suggesting AOB's importance in nitrification in global acidic soils.

Summary: The study found that ammonia-oxidizing archaea are more abundant in systems with low ammonium availabilities, while ammonia-oxidizing bacteria are more abundant when ammonium availability increases. Population dynamics of ammonia oxidizers may shift in response to changes in ammonium concentrations.

Summary: The discovery of ammonia-oxidizing archaea (AOA) and complete ammonia-oxidizing (comammox) bacteria in terrestrial ecosystems highlights their important role in nitrification. A nutrient-limited enrichment strategy was found to favor the growth of comammox bacteria with high affinity and yield. Direct enrichment from soil and nutrient-limited sub-cultivation consistently yielded high enrichments of Nitrosocosmicus-affiliated AOA associated with multiple canonical nitrite-oxidizing Nitrospira strains.

Summary: This study investigated the effects of applying Cu-complexing compounds on nitrification rate, abundance of ammonia-oxidizing bacteria and archaea genes, and mineral nitrogen leaching in urine patches. The results showed that using organic compounds such as co-poly-acrylic-maleic acid and calcium lignosulphonate can significantly reduce the copper content in the soil, thereby reducing mineral nitrogen leaching.

Summary: An aerobic N-15 microcosmic experiment was conducted to compare the inhibitory effects of the biological nitrification inhibitor (BNI), methyl 3-(4-hydroxyphenyl) propionate (MHPP) and the synthetic nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP) on the gross nitrification rate and the abundance and community composition of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in contrasting soils. The results showed that the two inhibitors had different effects on nitrification rates and the response of AOB to the inhibitors was more sensitive.

Summary: The study found that ammonia-oxidizing archaea and ammonia-oxidizing bacteria had significantly higher transcriptional abundance of amoA gene in soils compared to complete ammonia oxidizers, suggesting the former may be the dominant contributors to soil nitrification. Seasonal variation and fertilization regimes substantially affected the abundance of ammonia-oxidizing microbes, with ammonia-oxidizing bacteria being less sensitive to these factors compared to ammonia-oxidizing archaea.

Summary: The study showed that short-term low dissolved oxygen increased N2O emissions, while long-term low DO decreased emissions by increasing the abundance of ammonia oxidizers in the ASP. Long-term low DO reduced AOB abundance but increased AOA, with AOA potentially inhibiting N2O production. The positive correlation between N2O emissions and nitrite concentration became insignificant after 80 days of low DO operation, suggesting that ASPs can reduce N2O production and CO2 emissions by operating with low DO and extended sludge age.

Summary: This study found significant shifts in potential ammonia oxidation rates (PARs) and gene abundances of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) along different salinity gradients. The PARs were higher under high salinity conditions, and the AOB gene abundance was greater than AOA under moderate and high salinity. This has important implications for nitrogen cycling in estuarine sediments.

Summary: This study analyzed activated sludge samples from municipal and industrial wastewater treatment plants and found that comammox bacteria were more abundant than ammonia-oxidizing bacteria and ammonia-oxidizing archaea in municipal plants, while this trend did not hold true for industrial plants. Furthermore, a higher diversity of comammox bacteria was found in municipal samples. This study provides important insights into the abundance and diversity of comammox bacteria in municipal and refinery wastewater treatment systems.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

Summary: This study investigates the impact of biochar on methylmercury (MeHg) accumulation in rice. The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
