AB  - Anaerobic ammonium oxidation (anammox) is a type of biological oxidation mediated 
      by a group of Planctomycete-like bacteria. Members of the genus Candidatus 
      Scalindua are mainly found in marine environments, but not exclusively. This 
      group is cultured using different inoculums and conditions; however, its optimal 
      growth conditions are not clear. Additionally, little information is known about 
      the factors that influence the activity and the selection of a population of 
      marine anammox bacteria. This study was conducted to investigate the influence of 
      temperature and salinity on the marine anammox community. To accomplish this, an 
      up-flow fixed-bed column reactor was operated, and quantitative fluorescence in 
      situ hybridization (FISH) with probes specific to dominant marine anammox 
      bacteria was conducted. Anammox activity was observed at 20 and 30  degrees C, but not at 
      10  degrees C. A nitrogen removal rate of 0.32 kg TN m(-3) day(-1) was obtained at 20  degrees C. 
      These results suggest that temperature affects the activity (nitrogen removal 
      rate) of anammox bacteria, while salinity does not affect the activity in the 
      marine anammox biofilm.
