Summary: This study proved the coexistence of Feammox and NDFO in natural enrichment, forming nitrogen and iron cycles. Sodium acetate and 9,10-anthraquinone-2,6-disulfonate (AQDS) were found to promote the reaction. 16S rRNA sequencing revealed Pseudomonas, Rhodanobacter, Acinetobacter and Thermomonas as dominant genera in the enrichment cultures.

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: This study identified key microbial taxa regulating soil biogeochemical processes using metagenomic data from forest soils in eastern China, highlighting the sensitivity of soil pH as an indicator for functional gene composition and diversity. A bipartite network inferred from metagenomic contigs revealed microbial taxa regulating coupled biogeochemical cycles between carbon and phosphorus, nitrogen and sulfur, and nitrogen and iron, providing novel evidence for the coupling of soil biogeochemical cycles and demonstrating the efficacy of a new approach to investigate soil ecosystem functions.

Summary: Ammonium is a common form of nitrogen in wastewater, and new technologies are needed to effectively remove it to prevent severe pollution. Feammox, known as anaerobic ammonium oxidation coupled to Fe(III) reduction, is an efficient and environmentally friendly method that can be combined with other nitrogen removal reactions for wastewater treatment.

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: This study observed the coupling of anaerobic ammonium oxidation with As(V) reduction, known as Asammox, and identified the responsible bacteria in As-contaminated paddy soil. The discovery of Asammox expands the understanding of N and As biogeochemical cycling and provides a proof-of-concept for investigating anaerobic ammonium oxidation coupled with metal(loid)s reduction.

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: Iron-coupled anaerobic oxidation of methane (AOM) may be the dominant non-sulfate-dependent process for methane consumption in marine ecosystems. Studies summarize the conditions for iron-coupled AOM, and discuss the forms of iron oxides as electron acceptors and the microbial mechanisms involved.

Summary: This study investigated the diversity and abundance of n-damo bacteria in vegetated and non-vegetated sediments of a subtropical mangrove wetland. The results showed that the seasonal changes and vegetation had significant impacts on the n-damo bacterial community. The study further revealed that NH4+ and NH4+/NO2- were important factors influencing the diversity of n-damo bacteria in mangrove wetland sediments.

Summary: This review comprehensively analyzes the redox cycles of manganese in the environment, and discusses its importance in greenhouse gas mitigation, nutrient loading, microbial bioremediation, and global biogeochemical cycles. The oxidation and reduction of manganese occur cyclically and simultaneously in water, soil, and sediment environments, coupled with microorganisms, providing promising opportunities for the remediation of contaminated environments.

Summary: It was found that 20 μg/L of fluoroquinolones promoted the nitrogen removal performance of anammox microorganisms and removed 36-51% of the drugs. Metabolomics and genome-resolved metagenomic analysis revealed enhanced carbon fixation, purine and pyrimidine metabolism, protein generation, and transmembrane transport in anammox bacteria and symbiotic bacteria in response to 20 μg/L of fluoroquinolones. Consequently, hydrazine dehydrogenation, nitrite reduction, and ammonium assimilation were bolstered, improving the nitrogen removal efficiency of the anammox system.

Summary: The study reports a novel authigenic nanoscale magnetite source in marine methane seep sediments, with characteristics of larger particles and distinctive structures, mainly as a byproduct of microbial iron reduction within methanic sediments with rapidly changing redox conditions. This magnetite may have formed due to alterations in redox conditions within methane sediments.

Summary: The effects of PFOA on the nitrogen removal performance, microbial community, and functional genes in an ABR were investigated. The results showed that increasing PFOA concentration decreased the removal efficiencies of NH4+-N and NO2--N, as well as the relative abundance of specific microbial species and the expression of anammox genes in the sludge.

Summary: Water pollution remains a serious issue in certain parts of China. The study shows that the majority of non-point source pollution load in the Paihe River basin comes from agricultural and construction land, with land use changes playing a crucial role in pollution load. The use of clean water corridor technology can effectively reduce non-point source pollution load, and a comprehensive adoption of this technology is necessary to achieve ecological environmental restoration goals.

Summary: Urban agglomeration has become the main regional unit to cope with global challenges. However, with the development of economic globalization and urbanization, urban agglomeration is facing increasing pressure on nature resources and ecological environment. The study on the Fujian Delta Urban Agglomeration in China reveals that it is a consumption-orientated economic system dominated by non-renewable resource input, with moderately uncoordinated regional social-economic and resource-environment systems. Cross-regional cooperation is important for achieving sustainable development and a win-win situation between cities.

Summary: North Creek of Jiulong River is relatively healthy in summer and fall, but exhibits the worst conditions in winter. More than 50% of sites in the dam reservoir area have lower than moderate ecological health assessments, with the mainstream having lower health levels than tributaries. The PIBI index is correlated with basic water physicochemical parameters and can be used to evaluate river health status effectively.

Summary: Soil erosion is a severe environmental problem in China, and soil and water conservation measures have played a crucial role in reducing streamflow and sediment yields. This study quantitatively explored the hydrological effects of these measures in the Tingjiang River Watershed, using a nested watershed approach and various statistical analyses. The results showed a significant downward trend in annual streamflow and sediment yields since the implementation of soil and water conservation measures, indicating their significant impact. Precipitation had a larger influence on streamflow than the conservation measures, but the contribution of the measures to sediment yields gradually dominated in the watershed. The establishment of an ecological threshold at 10% afforestation area revealed remarkable improvements in hydrological effects.
