AB  - The diversity and abundance of ammonia-oxidizing Betaproteobacteria and archaea 
      were investigated in a full-scale municipal wastewater treatment plant where the 
      wastewater conductivity level varied considerably (due to seawater salinity 
      intrusion) during this study between 2004 and 2007. Based on the quantitative 
      polymerase chain reaction of ammonia monooxygenase subunit A (amoA) genes, an 
      increase in the ammonia oxidizing bacteria amoA gene copies occurred with a 
      decrease in the wastewater salinity level. A corresponding decrease in the 
      average ammonia-oxidizing archaea to bacteria ratio, from 1.22 (2004 and 2005), 
      0.17 (2006), and then to 0.07 (2007), was observed. Phylogenetic analyses on amoA 
      gene sequences indicated that Nitrosomonas marina-like ammonia oxidizing bacteria 
      and Thaumarcheota Ⅰ.1a (marina group) ammonia-oxidizing archaea were dominant 
      when the wastewater salinity level fluctuated at high values with an average of 
      4.83 practical salinity unit (psu), while Nitrosomonas urea-like ammonia 
      oxidizing bacteria and Thaumarcheota Ⅰ.1b (soil group) ammonia-oxidizing archaea 
      became dominant when the wastewater salinity decreased to a more stable lower 
      level with an average of 1.93 psu. Based on the amoA gene-based terminal 
      restriction fragment length polymorphism analyses, results from this study 
      demonstrated that the observed shift in ammonia oxidizing bacteria and archaea 
      populations is likely caused by a change of the wastewater salinity level.
