Summary: Acidic partial nitritation (PN) is a stable method for wastewater treatment that can achieve nitrite accumulation and ammonium reduction. However, directly applying anaerobic ammonium oxidation (anammox) to treat acid PN effluent is problematic. This study demonstrated the adaptation of anammox to acidic pH in a moving bed biofilm reactor (MBBR), achieving high nitrogen removal efficiency. The presence of biofilm plays a critical role in protecting anammox bacteria in acidic environments.

Summary: This study addressed the issues of sludge floating and uneven mass transfer in up-flow partial denitrification/anammox (PDA) reactors by implementing two strategies: adding biological carriers and applying mechanical stirring. The results showed that both strategies effectively prevented sludge flotation and deterioration of settling performance. Mechanical agitation had a more significant positive impact on PDA performance compared to the addition of biocarriers as it achieved more adequate mass transfer.

Summary: This study demonstrates the coexistence of denitrification, DNRA, and anammox processes in a highly saline lake, with their contribution determined by environmental conditions such as oxygen and light. DNRA, especially denitrification to N2O, were the dominant nitrogen removal pathways in the presence of oxygen and/or light. Conversely, anoxia and darkness promoted NO3- reduction by DNRA combined with N loss by anammox.

Summary: In this study, a halotolerant bacterium Halomonas sp. 3H was isolated from a eutrophic saline lake sediment, which could remove ammonium nitrogen and nitrate/nitrite nitrogen via aerobic denitrification in high-salinity wastewater and reduce the production of greenhouse gas N2O. The strain could also remove added N2O with the further addition of Cu2+, showing its potential to mitigate complex and significant climate changes.

Summary: The study investigated the variation of nitrogen components in different aquatic ecosystems and found that nitrogen removal occurred during water flow, with a reduction rate of up to 43%. The heterogeneity in eco-stoichiometric characteristics of nitrogen components was higher in ditches and ponds compared to rivers and reservoirs. Ditches and ponds showed stronger interactions between overlying water and sediment, with higher rates of denitrification and anaerobic ammonium oxidation. The findings emphasize the importance of focusing on the upper reaches of agricultural catchments for nitrogen removal and developing region-specific conservation strategies to mitigate nitrogen pollution and protect water resources.

Summary: The formation, performance, and microbial community structure of aerobic granular sludge (AGS) were investigated in the presence and absence of oxytetracycline (OTC). The results showed that the addition of OTC promoted the formation of well-settling AGS, but decreased the removal rates of nitrogen and phosphorus. This study is important for understanding the impact of antibiotics on AGS and designing treatment methods for antibiotic-laden wastewaters.

Summary: The enhancement of nitrogen removal was achieved through the nitritation/anammox process in an anaerobic/oxic/anoxic (AOA) system with integrated fixed biofilm activated sludge. Nitritation was initially accomplished by inhibiting ammonia residues using free nitrous acid (FNA), and anaerobic ammonia oxidizing bacteria (AnAOB) were subsequently introduced into the system to enable nitritation coupled with anaerobic ammonia oxidation (anammox). The results demonstrated that the nitritation/anammox pathway significantly enhanced nitrogen removal efficiency to 88.9%. Microbial analysis revealed the enrichment of ammonia oxidizing bacterium (AOB) Nitrosomonas on the biofilm (5.98%) and in the activated sludge (2.40%), while the AnAOB Candidatus Brocadia was detected on the biofilm at a proportion of 0.27%. The successful achievement and maintenance of nitritation/anammox were attributed to the accumulation of functional bacteria.

Summary: The research found that anaerobic ammonium oxidizing (anammox) bacteria are highly sensitive to fluctuations in oxygen concentration and temperature under mainstream wastewater treatment conditions, leading to inhibition that affects the efficiency of nitrogen removal. Genomic analysis showed that changes in temperature and oxygen concentration resulted in alterations in gene expression levels within microbial communities, affecting the nitrogen removal process.

Summary: Organic micropollutants (OMPs) can be biotransformed by ammonia-oxidizing bacteria through direct and indirect enzymatic reactions, primarily via hydroxylation and deamination. Ammonia-oxidizing bacteria play a key role in OMP biotransformation during wastewater treatment processes, especially through the activity of the ammonia monooxygenase enzyme.

Summary: Chronic exposure to zinc oxide nanoparticles in a sequencing batch reactor has shown dose-dependent depression effects on ammonia nitrogen and total nitrogen removal efficiencies as well as N2O emissions. The suppressed N2O emissions were positively correlated with the activity ratios of nitrite/NO reductases and N2O reductase.

Summary: This study investigated the phylogeny of resident N2O-reducing bacteria in an anammox microbial community and quantified individually the processes of N2O production and consumption. The results showed that N2O-reducing bacteria primarily belonged to Burkholderiaceae and Chloroflexus genera, and other less abundant strains in Rhodoferax, Azospirillum, Lautropia, and Bdellovibrio also likely acted as N2O sinks. The study also introduced a novel N-15 tracer method to quantify N2O production and consumption rates, providing insights into the potential N2O-reducing activity in anammox-based processes.

Summary: This study identified Candidatus Nitrospira nitrosa-like comammox bacteria as the predominant ammonia oxidizers in a lab-scale BNR system, with the potential to use acetate and propionate, stimulate ammonia oxidation rate, and interact metabolically with heterotrophs. Comammox bacteria have shown to provide vitamins/cofactors to heterotrophs and receive amino acids in return, contributing to their survival in the system and outcompeting ammonia oxidizing bacteria. Systems with comammox bacteria as the major nitrifiers have great potential for superior performance with low aeration cost and N2O emission at full-scale plants.

Summary: Current in the milliampere range can enhance conjugal plasmid transfer between bacteria, including antibiotic-resistant bacteria. The exposure to sublethal current intensities during electrochemical disinfection can lead to increased transconjugant frequency and expression of conjugation-related genes. It is crucial to carefully control the conditions of electrochemical disinfection to prevent the transmission of antibiotic resistance genes.

The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
