“…N. marina belonging to the so-called Nitrospira lineage IV (Daims et al, 2001) has been detected previously in saltwater aquaria (Hovanec et al, 1998), marine biofilters (Tal et al, 2003), and marine recirculation aquaculture system (Foesel et al, 2008). In addition, N. marina was also the major group in the sediments of Nanliu (NL) River Estuary (Zhao et al, 2021) and in the water column of the Pearl River in winter (Hong et al, 2021). N. marina was predominant and ubiquitous in the DYB (STE), which predicted the potentially important role of N. marina in nitrite oxidation during nitrification in the STE.…”

“…A less diverse microbiology community appeared to be associated with salinity in most cases (Hong et al, 2019). N. marina affiliated to lineage IV has widely adapted to variable salinity (Zhao et al, 2021), which may make it widely present in salinity ecosystems, including deep sea, estuary area, and saline soils (Pester et al, 2014;Hong et al, 2021;Li et al, 2021;Zhao et al, 2021).

“…The abundance of the nxrB gene and distribution of OTU02 were both significantly correlated with ammonium in the DYB (STE). Ammonium was also reported to be the most important factor influencing Nitrospira distribution in the water column of the PRE (Hong et al, 2021). Therefore, DOC and ammonium concentrations regulated by the dynamics of the STE may be the main factors driving the community composition and distribution of Nitrospira in the DYB (STE).…”

The oxidation of nitrite to nitrate as the second step of nitrification is vital for the global nitrogen cycle, and the genus Nitrospira is the most widespread nitrite-oxidizing bacteria (NOB) in diverse natural ecosystems. However, our understanding of Nitrospira distribution and their response to dynamic environmental parameters is still limited in the subterranean estuary (STE), a special environment of the mixed zone between land and sea. In this study, Nitrospira communities were collected within 5–10 cm depth intervals of sediments with the physiochemical gradients along the transections of the Daya Bay (DYB) from the landward member to the seaward member. The abundance, community structure of Nitrospira, and their potentially influencing environmental factors were investigated using Q-PCR, the high throughput sequencing targeting Nitrospira nxrB gene, and biostatistics analyses. The abundance of Nitrospira showed uniform distribution along the transections, but significantly decreasing variations were observed from the surface (<20 cm) to the bottom (>20 cm) of sediments. The community diversity and structure of Nitrospira also displayed a remarkable vertical distribution in the DYB (STE), although no significant differences were observed along the transections of STE. Nitrospira marina (N. marina) predominated in the sediments, Candidatus Nitrospira bockiana (Ca. N. bockiana), and Candidatus Nitrospira defluvii (Ca. N. defluvii) were the main Nitrospira species, and Candidatus Nitrospira lenta (Ca. N. lenta) and Nitrospira japonica (N. japonica) also existed with relatively low abundance in the DYB (STE). These findings revealed that Nitrospira species (Ca. N. defluvii, Ca. N. lenta, and N. japonica) derived from activated sludge was also widespread in natural habitats and deduced that the STE may be affected by the pollution derived from terrigenous human activities. The statistical analysis combined with the STE dynamic variation indicated that dissolved organic carbon (DOC), salinity, and ammonium along the sediment depths attributed to the vertical community distribution of the Nitrospira species. In summary, the vertical distribution of Nitrospira and their response to the dynamic physicochemical parameters imply their important role in the nitrite oxidation of the STE and provide insights into the niche differentiation and diversely physiologic metabolism of NOB.

In estuarine sediment, the nitrite oxidation process mediated by bacteria is signi cant in the nitri cation process. Nitrospira is the most widely distributed in diverse group of nitrite-oxidizing bacteria (NOB), and can adapt to various environment. In this study, the Nitrospira-speci c primer nxrB 169F-638R was used to analyze the microbial communities in the sediments of low-, middle-, and high-level zones of the Luan River estuary. The structure of microbial community and its response to environmental factors were discussed. The abundance and diversity of Nitrospira were the highest in the low-level zone and the lowest in the high-level zone. Lineage II (43.58%) and lineage IV (32.09%) were the dominant Nitrospira. It was found that the distribution pattern of Nitrospira was also affected by complex environmental factors such as the concentration of NH 4 + , Fe and Cu cations. Therefore, this study is helpful in understanding the niche differentiation and adaptation strategies of Nitrospira in an estuarine sediment environment and in providing references for single-step nitri cation.

Nitrification–denitrification is an environmentally friendly and cost-effective way to treat landfill leachates. Special attention has been given to the nitrification step, usually the limiting one due to its special sensitivity to environmental factors. Here, the effect of the acclimatization of the nitrifying biomass to two different intermediate landfill leachates with different salt concentrations, COD and BOD5 has been studied. Despite the complete nitrification being successfully performed, the specific nitritation rates were reduced after the biomass adaptation to both landfill leachates caused by the presence of heavy metals and the high salt concentration. NGS analysis of the biomass samples revealed that Proteobacteria (48.5%), Actinobacteriota (14.4%) and Chloroflexi (9.5%) were the dominant phyla in the non-adapted biomass. The leachate feeding led to a decrease in OTU diversity and favored the growth of the phyla Bacteroidetes (27.2%), Euryarchaeota (26.6%) and Proteobacteria (20.0%) accounting for more than 70% of relative abundance. Several OTUs capable of performing the nitritation belong to the Xanthobacteraceae and the Xanthomonadaceae families, the Saccharimonadales order, and the genus Nitrosomonas, Nitrosospira and Paracoccus. In the nitratation process, the Xanthobacteraceae family and Lautropia and Nitrolancea genera were found. Graphical Abstract
