AB  - This study evaluated nitrification performance and microbial ecology of 
      nitrifying sludge in two full-scale wastewater treatment plants (WWTPs) including 
      a municipal WWTP treating 20mgNL(-1) of ammonium and a swine WWTP treating 
      220mgNL(-1) of ammonium. These two plants differed in both wastewater 
      characteristics and operating parameters, such as influent COD, TKN, ammonium, 
      hydraulic retention time, and solids retention time, even though both plants 
      achieve >85% nitrification efficiency. By employing molecular techniques, 
      including terminal restriction fragment length polymorphism, cloning-sequencing 
      and phylogenetic analyses targeting the 16S ribosomal RNA and group specific 
      ammonia-monooxygenase functional gene (amoA), microbial community structures of 
      nitrifying sludge and their significance to nitrification performance were 
      evaluated. The results reveal that for the municipal WWTP Nitrosomonas 
      marina-like AOB (ammonia-oxidizing bacteria) and Nitrospira-like NOB 
      (nitrite-oxidizing bacteria) were the ubiquitously dominant nitrifiers, while 
      Nitrosomonas europaea-, Nitrosomonas oligotropha-, and Nitrosospira-like AOB and 
      Nitrobacter- and Nitrospira-like NOB were the major nitrifying populations found 
      in the swine WWTP. The observed dissimilar nitrifying populations prevailing in 
      these two plants may be related to niche differentiation concerning ammonium 
      concentrations, system operation, and salinity. Moreover, our results suggest 
      that the swine nitrifying sludge, involving relatively diverse AOB and NOB 
      populations that perform the same task but with distinct growth and survival 
      characters, may allow communities to maintain nitrifying capabilities when 
      conditions change such as sudden increases in ammonium concentrations as examined 
      with nitrification kinetic batch tests.
