英文摘要	Recent studies have confirmed the existence of aerobic denitrifying bacteria, particularly exploring their diversity and heterotrophic nitrification-aerobic denitrification capability in a wastewater treatment plant (WWTP). In this study, the sewage treatment technology, which combined a rotating biological contactor (RBC) with an anaerobic-anoxic-oxic-oxic (A(2)/O-2) process, demonstrated strong removal efficiency for nitrate pollutants. Five types of activated sludge in a WWTP were used to isolate 226 strains of aerobic denitrifying bacteria, which were classified into 12 genera based on the 16S rDNA. Pseudomonas stutzeri, Pseudomonas monteilii, and Gordonia cholesteroliborans were the most abundant aerobic denitrifying bacteria in the five types of activated sludge. P. stutzeri, Pseudomonas pseudoalcaligenes, Pseudomonas chengduensis, Beijerinckia fluminensis, and Arthrobacter protophormiae demonstrated strong heterotrophic nitrification-aerobic denitrification capacity. G. cholesteroliborans, Pseudomonas pseudoalcaligenes, P. chengduensis, and B. fluminensis also showed aerobic denitrifying capacity, which was not reported previously. The Venn diagram and the relative abundance diagram revealed the different structures of aerobic denitrifiers among the five types of activated sludge. This study may provide a reference for screening and application of aerobic denitrifying bacteria in WWTPs.
