AB  - Spatial distributions of ammonia oxidizing bacteria (AOB) and nitrobacteria in a 
      renovated suspended carrier biofilm reactor (SCBR) were investigated by using 
      fluorescence in situ hybridization (FISH) with 16S rRNA oligonucleotide probes in 
      combination with confocal laser scanning microscopy (CLSM). Three bench-scale 
      structurally identical SCBR reactors were operated under different ratios of COD 
      to NH4(+) -N in influents, 5, 10 and 15, respectively. Each SCBR reactor was 
      consisted of a 6 L of aeration basin and a 2L of clarifier, with the hydraulic 
      retention time (HRT) of 1.0h. The monitoring results showed that the thickness of 
      biofilm in the SCBR was about 80 to 120 micron. Both the total amount of AOB and 
      nitrobacteria decreased with depth in biofilm, most of the nitrification bacteria 
      communities lied in the upper layer of biofilm, about 20 to 30 micron. The 
      proportion of AOB to all bacteria in biofilm decreased when the ratio of COD to 
      NH4(+) -N increased.
