AB  - The changes of microbial population structure in biofilm caused by variations of 
      COD/NHNH4(+)-N ratio in influent were investigated in a suspended carrier biofilm 
      reactor (SCBR). When COD/NHNH4(+)-N was 10, the highest COD removal reached was 
      about 73.8 per cent, whereas the highest NH4(+)-N removal, about 55.9 per cent, 
      was reached when COD/NH4(+)-N was 5. By using fluorescence in situ hybridization 
      (FISH) and confocal laser scanning microscopy (CLSM) observation, it was found 
      that the thickness of the biofilm formed on the carrier was about 80 to 120 
      microm, and ammonia-oxidizing bacteria (AOB) and nitrifying bacteria existed 
      mainly in the upper layer about 20 to 30 microm. The results of the quinone 
      profile analysis showed that when the COD/NH4(+)-N increased, the microbial 
      diversity (DQ) increased, while the proportions of AOB and nitrifying bacteria in 
      the biofilm communities decreased.
