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.
