Excessive ammonia (NH3) emitted from nitrogen fertilizer application in farmland have caused serious disturbance to global environment, including reduction of visibility, formation regional haze, and increase deposition. Application biofertilizer has been considered as an effective approach for soil improvement agriculture sustainability. In this study, a field experiment was conducted evaluate the potential B. subtilis on mitigating NH3 volatilization investigate underlying mechanisms. Compared with organic fertilizer, incorporation reduced by up 44%. Moreover, abundance ureC gene, increased functional genes (bacterial amoA comammox amoA) ammonia-oxidizing bacteria (AOB). This indicated that conversion NH4+-N decreased nitrification process increased. brief, "source" "sink" NH4+-N, thus reducing retention alkaline soil, volatilization. These results is control strategy agricultural emission, maintaining high crop yield environmental disturbance.

Complete ammonia oxidizers (comammox), able to individually oxidize nitrate, are considered play a significant role in the global nitrogen cycle. However, distribution of comammox Nitrospira estuarine tidal flat wetland and environmental drivers affecting their abundance diversity remain unknown. Here, we present large-scale investigation on geographical along wetlands China, where were successfully detected 9 16 sampling sites. The ranged from 4.15 × 105 6.67 106 copies/g, 2.21- 5.44-folds lower than canonical oxidizers: ammonia-oxidizing bacteria (AOB) archaea (AOA). Phylogenetic analysis based alpha subunit monooxygenase encoding gene (amoA) revealed that Clade A, mainly originating upstream river inputs, accounts for more 80% Nitrospira, whereas clade B rarely detected. Comammox dominant OTUs varied within samples, showing pattern. Salinity pH most important wetlands. was further negatively correlated with high nitrite concentrations. Altogether, this study existence, driving factors ecosystems, thus providing insights into ecological niches recently discovered nitrifying consortium contributions nitrification environments.

The discovery of complete ammonia oxidation (comammox) has altered our understanding nitrification, which is the rate-limiting process in global nitrogen cycle. However, ecological role comammox or its contribution to nitrification both natural and artificial ecosystems still infancy. Here, we investigated community distribution function bacteria riparian analyzed interactions between other cycling microorganisms. bacterial abundance rate were higher summer than winter nonrhizosphere soils rhizosphere. Fringe zone comprise a hotspot, where (2.58 × 108 copies g–1) (0.86 mg N kg–1 d–1) not only at sampling sites but also those processes. correlated significantly positively with relative species Candidatus Nitrospira nitrificans that nitrosa. Analysis interaction ammonia-oxidizing processes revealed archaea dominate interface soils, fringe anaerobic ammonium (anammox) sediments zone. These results indicate may constitute an important currently underestimated microbial ecosystems.

The discovery of complete ammonia oxidizers, comammox Nitrospira, represents a breakthrough in the history nitrification research. Nitrospira inopinata, which was obtained from an aquatic ecosystem, is only pure bacterial isolate reported so far. Ammonia oxidation kinetics N. inopinata indicated that they prefer oligotrophic lifestyle and may directly compete with ammonia-oxidizing archaea (AOA), but representatives terrestrial ecosystems are lacking. Current studies demonstrate functionally dominant separated most sequences engineering systems. Clades A B seemingly have different ecological preferences soils, possibly due to their ammonium uptake Analyses evolutionary indicate some genes involved could be laterally transferred β-ammonia-oxidizing bacteria (AOB). Some species similar AOB active niches where previously considered dominated by AOB. Taken together, this review summarizes recent findings biogeographical distribution preference large-scale soil surveys, responses nitrogen application soil, putative mechanisms underpinning niche Nitrospira. These suggest not strictly both copiotrophic broader breadth. Comammox abundant environments. profoundly expanded our knowledge environmental relative contribution soils.
