AB  - Ammonia-oxidizing microbial communities involved in ammonia oxidation under low 
      dissolved oxygen (DO) conditions (<0.3 mg/L) were investigated using chemostat 
      reactors. One lab-scale reactor (NS_LowDO) was seeded with sludge from a 
      full-scale wastewater treatment plant (WWTP) not adapted to low-DO nitrification, 
      while a second reactor (JP_LowDO) was seeded with sludge from a full-scale WWTP 
      already achieving low-DO nitrifiaction. The experimental evidence from 
      quantitative PCR, rDNA tag pyrosequencing, and fluorescence in situ hybridization 
      (FISH) suggested that ammonia-oxidizing bacteria (AOB) in the Nitrosomonas genus 
      were responsible for low-DO nitrification in the NS_LowDO reactor, whereas in the 
      JP_LowDO reactor nitrification was not associated with any known 
      ammonia-oxidizing prokaryote. Neither reactor had a significant population of 
      ammonia-oxidizing archaea (AOA) or anaerobic ammonium oxidation (anammox) 
      organisms. Organisms isolated from JP_LowDO were capable of autotrophic and 
      heterotrophic ammonia utilization, albeit without stoichiometric accumulation of 
      nitrite or nitrate. Based on the experimental evidence we propose that 
      Pseudomonas, Xanthomonadaceae, Rhodococcus, and Sphingomonas are involved in 
      nitrification under low-DO conditions.
