“…5B). These results were distinctly different from those of eutrophic lakes (Lake Taihu and Lake Chaohu), which showed that Nitrosomonas-and Nitrosospira-like AOB dominated in these lakes (Hou et al 2013;Liu and Yang 2021). Consistent with our results, in a previous study on urban river section, Lin et al (2020) found that there were Nitrosomonadaceae-like AOB in water samples.…”

Ammonia-oxidizing bacteria (AOB) attached to aquatic particles are important participants in ammonia oxidation within hypereutrophic urban river systems. To explore the effects of aquatic nitrogen pollution on particle-attached AOB in urban river, we utilized laboratory mesocosms to investigate the responses of abundances and community structure of particleattached AOB to ammonium (NH 4 + ) and glycine (C 2 H 5 NO 2 ) amendments. The abundance and community structure of particle-attached AOB were determined with quantitative real-time polymerase chain reaction (qRT-PCR) analysis and high-throughput sequencing based on the AOB amoA gene, respectively. Most of the bacterial amoA sequences from different treatments were affiliated with uncultured Nitrosomonadaceae bacterium, uncultured Nitrosomonadales bacterium, and uncultured Nitrosomonas sp., which are closely associated with organic pollution. The species richness and diversity of particle-attached AOB communities increased with increasing NH 4 + and glycine concentrations. Treatment effects contributed significantly to the variance in particle-attached AOB communities. Although, glycine was completely transformed to ammonium within a few days and ammonium amendments would change the community structure of particle-attached AOB, the effect of glycine on the particle-attached AOB community was regulated by both the resulting ammonium concentration, as well as organic matter availability to the heterotrophic bacteria. Results suggested that high anthropogenic nitrogen loadings appeared to promote higher particle-attached AOB richness and diversity in the hypereutrophic urban river, but the effect of organic nitrogen on the particle-attached AOB community was different from the effect of inorganic nitrogen. This study informs ammonia oxidization mechanisms in the hypereutrophic urban rivers, which contributes to remediation/ restoration strategies.

“…Despite the massive research, the actual dynamics of AOA and AOB communities in environments especially when subjected to disturbance are still not very clear, probably due to their complex responses to environmental changes at both temporal and spatial scales. Studies of different layers in water bodies have shown significant seasonal changes in AOA and AOB communities ( Vissers et al, 2013 ; Muller et al, 2018 ), while many other studies have discovered no or little seasonality in ammonia oxidizers in the sediments of estuaries ( Zheng et al, 2014 ; Smith et al, 2015 ), lakes ( Liu and Yang, 2021 ), natural wetlands ( Wang et al, 2013 ; Gao et al, 2018 ), constructed wetlands ( Wang et al, 2019 ), and biofilms ( Bagchi et al, 2014 ), indicating that the responses of ammonia-oxidizing communities to seasonal variables may differ. Two previous studies have observed some seasonal trends in abundances of ammonia-oxidizing microorganisms in aquaculture ponds ( Kumari et al, 2011 ; Lu et al, 2015 ), but no significant seasonal differences could be identified because there were not enough samples for statistical analysis.…”

“…Both groups use ammonia as their sole energy source ( Konneke et al, 2014 ; Lehtovirta-Morley et al, 2016 ), although some of them are reported to be able to assimilate amino acids ( Mussmann et al, 2011 ). As a result of their importance in nitrogen cycling and their potential use in ammonia removal, for instance through coupled nitrification–denitrification processes, AOA and AOB have been well-studied in various habitats, including oceans ( Francis et al, 2005 ; Sintes et al, 2015 ), estuaries ( Zheng et al, 2014 ; Smith et al, 2015 ), lakes ( Liu and Yang, 2021 ), soils ( Pester et al, 2012 ; Shen et al, 2021 ), and wetlands ( Wang et al, 2013 , 2019 ). For example, many factors have been shown to affect the composition and abundance of AOB and AOA, including pH, temperature, salinity ( Santos et al, 2020 ), ammonia concentration ( Taylor et al, 2012 ), nutrient levels ( Dai et al, 2018 ), competition ( French et al, 2021 ), and predators ( Kim et al, 2019 ).…”

Ammonia-oxidizing archaea (AOA) and bacteria (AOB) play an important role in nitrification, which is essential in the global nitrogen cycle. However, their dynamics and the underlying community processes in agricultural ecosystems under disturbance remain largely unknown. In this study we examined the spatiotemporal dynamics of AOA and AOB communities and analyzed their community processes in the sediment of aquaculture ponds across three different areas in China. We found some significant temporal changes in AOA and AOB community diversity and abundances, but no temporal changes in community composition, despite the significant variations in sediment properties between different sampling times. Nevertheless, significant differences were found for AOA and AOB communities between different areas. Distinct area-specific taxa were detected, and they were found to be important in determining the response of AOA and AOB communities to environmental factors. In addition, geographic distance was found to be significantly correlated with AOA and AOB community composition, which demonstrates that dispersal limitation could significantly contribute to the variations in AOA and AOB communities, and stochastic processes were found to be important in structuring AOA/AOB communities in aquaculture ponds. Taken together, our study indicates that the dynamics of AOA and AOB are based on their community characteristics in aquaculture pond sediment. Our results, for the first time, provide evidence for the dynamics of AOA and AOB communities being driven by stochastic factors in a disturbed environment, and might also be of use in the management of the aquaculture environment.

“…NH 3 hydrolysis increases the environmental pH and induces the formation of carbonate, which reacts with divalent cations in the environment to form carbonate precipitates [55]. At present, there are few studies on ammonifying bacteria, few studies focus on environmental nitrogen cycling [69,70], and research on microbial mineralization is limited.…”

Microbial-induced mineralization is a process in which metal ions in the environment are processed by microorganisms, forming deposits of crystals with cementing and void-filling functions. Cementing crystals can fix metal ions, reduce permeability, improve soil strength, and play a positive role in soil remediation and pollution control. This paper first introduces the principle of microbial-induced mineralization and analyzes its mechanism of action in the treatment of soil organic and inorganic pollutants. Then, the mineralization principle of different types of mineralized bacteria in soil (fungal metabolism involving organic acid complexation and metabolic urease catalysis, sulfur oxidation by sulfur-oxidizing bacteria, dissimilatory sulfate reduction by sulfate-reducing bacteria, ammonification by ammoniating bacteria, reverse digestion by denitrifying bacteria, urease catalysis by urease-producing bacteria, acetic acid fermentation by methanogenic bacteria, and H2/CO2 reduction) is elaborated, the influencing factors in the treatment of soil pollutants by mineralization technology in practical application are analyzed, and the current status of mineralization treatment for different types of pollutants is summarized. Finally, the future prospects of soil pollutant treatment are outlined to promote research into microbial-induced mineralization technology for the treatment of soil pollutants.
