Summary: Acidimicrobium sp. Strain A6 can degrade perfluoroalkyl acids (PFAAs) by oxidizing NH4+ while reducing Fe (III). Coating ferrihydrite particles with polyacrylic acid (PAA) with negative surface charge enhanced the Feammox activity and PFOA degradation. This study provides insights into the potential of PAA-coated ferrihydrite for PFAS defluorination.

Summary: Feammox is a process that removes ammonium through the reduction of Fe(III) and oxidation of ammonium. It has potential applications in wastewater treatment. Acidimicrobiaceae sp. A6 is the first isolated Feammox functional bacteria. The nitrogen removal effect of Feammox is influenced by environmental factors and requires further exploration.

Summary: This study investigated an anammox-derived Feammox process with an intermittent dosage of Fe2O3 and proposed a novel approach to reduce the Fe(III) consumption. The results showed that ammonium removal was mainly achieved through Feammox, while partial nitrification/anammox also played a role at super-low oxygen concentrations.

Summary: The study investigates the impact of Hurricane Florence on the biogeochemistry of riverine and riparian sediments in the Neuse River Watershed in North Carolina. It reveals that the unique environment created by high NH4+ concentrations, acidic conditions, and elevated levels of ferric iron supports the Feammox process carried out by Acidimicrobium sp. A6, which may serve as an important mechanism for NH4+ removal in the river system. The results also suggest that major hydrologic storm events can enhance Feammox activity in riverine sediments by delivering Fe(III).

Summary: This study focused on the Feammox mechanism in activated sludge obtained from a sewage treatment plant, showing that FeCl3 was more effective as an iron source for the oxidation of NH4+ and the reduction of Fe(III) to Fe(II). The research provides valuable information on the potential of Feammox in removing N from wastewater and the oxidation/reduction yields in the initial enrichment phase.

Summary: Feammox is a novel pathway for ammonium (NH4 (+)) oxidation and nitrogen cycle, leading to significant loss of nitrogen in natural environments. Various Feammox pathways, end products, and interactions within microbial communities have been revealed by researchers, offering alternative processes for wastewater treatment. However, substantial variations exist among different studies in terms of key functional microorganisms.

Summary: The Feammox process plays a crucial role in the natural nitrogen cycle, but has been rarely investigated in the field of wastewater treatment. This study explored the potential of anaerobic ammonium removal coupled with organics to assess the Feammox process for conventional wastewater treatment. Results showed that the Fe2O3 group had the highest efficiency in ammonium removal, while organics significantly inhibited the Feammox process.

Summary: Fe(III) reduction coupled with anaerobic ammonium oxidation (Feammox) is a newly discovered biological ammonium removal technology that is more tolerant to heavy metals and does not require NO2--N as a reaction substrate. This study investigated the effects of Fe/N, pH, and temperature on Feammox performance and found that the optimal working conditions were Fe/N of 0.15, pH of 6.5, and temperature of 30 degrees C.

Summary: This study reviewed the research on enhanced constructed wetlands (CWs) for the removal of heavy metals and metalloids (HMMs) from polluted water. A bibliometric analysis was performed to evaluate research trends, critical literature, and keyword evolution. The study found that research on CW technology for the remediation of HMM-polluted water is receiving increased attention, with no apparent trends in topics. Suggestions for optimizing the design and operation of efficient CWs for HMM-polluted water treatment are proposed based on the established literature.

Summary: The Feammox process, which involves Fe(III) reduction coupled to anaerobic ammonium oxidation, plays a key role in the nitrogen cycle in natural environments. However, the application of Feammox in wastewater treatment is limited by the need for continuous Fe(III) supplementation. This study demonstrated that intermittent aeration with air could facilitate the Fe(II)/Fe(III) cycle in the Feammox system for continuous nitrogen removal, providing a potential in situ remediation method for treating high-content NH4+.

Summary: Partial nitrification (PN)-Anammox is considered the optimal nitrogen removal process for municipal sewage, but NOB growth under low temperature and low-ammonium conditions leads to excessive NO3--N production. The cyclic utilization of Fe2+/Fe3+ in Feammox and NDAFO processes can achieve continuous conversion of NH4+-N and NO3--N without sludge mineralization. Coupling Feammox and NDAFO with Anammox enhances the conversion of NH4+-N to N-2.

Summary: Traditional nitrogen transformation processes in constructed wetlands involve aerobic nitrification and anoxic denitrification, but recent research has discovered novel pathways like anaerobic ammonium oxidation, heterotrophic nitrification, and aerobic denitrification, which can be enhanced by enriching specialized bacteria through selection pressures. Understanding these novel pathways and associated microbial populations can provide new insights for designing constructed wetlands for enhanced nitrogen removal.

Summary: Antibiotics and disinfectants, while saving lives and curing diseases, become micropollutants in the environment and contaminate water, threatening soil microbial communities, crop health, and perpetuating antimicrobial resistance. As water scarcity drives increased reuse and waste stream management, it is important to understand the fate of these chemicals and mitigate their adverse impacts on public health and the environment. In this review, we provide an overview of the concerns associated with increasing concentrations of antibiotics in the environment, their health risks for humans, and potential bioremediation strategies.

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.
