主　　题：Anammox Candidatus Brocadia Functional potential Cooccurring mechanisms Swine wastewater treatment facilities 

摘      要：The increasing application of anammox processes suggests their enormous potential for nitrogen removal in wastewater treatment ***,the functional potentials and ecological differentiation of cooccurring anammox species in complex ecosystems have not been well ***,by utilizing functional reconstruction and comparative genome analysis,we deciphered the cooccurring mechanisms of four Candidatus Brocadia species that were spontaneously enriched in a full-scale swine wastewater treatment *** analysis indicated that species SW172 and SW745 were closely related to *** caroliniensis and *** sapporoensis,respectively,whereas the dominant species SW510 and SW773,with a total average abundance of 34.1%,were classified as novel species of the genus *** reconstruction revealed that the novel species SW510 can encode both cytochrome cd1-type nitrite reductase and hydroxylamine oxidase for nitrite *** contrast,the detected respiratory pentaheme cytochrome c nitrite reductase and acetate kinase genes suggested that SW773 likely reduced nitrite to ammonium with acetate as a carbon ***,the presence of genes encoding urease and cyanase indicated that both novel species can use diverse organic nitrogen compounds in addition to ammonia and nitrite as *** together,the recovery and comparative analysis of these anammox genomes expand our understanding of the functional differentiation and cooccurrence of the genus *** in wastewater treatment systems.
