AB  - In this work, the heterotrophic growth on the microbial products of autotrophs 
      and the effecting factors were evaluated with both experimental and modeling 
      approaches. Fluorescence in situ hybridization (FISH) analysis illustrated that 
      ammonia oxidizers (AOB), nitrite oxidizers (NOB), and heterotrophs accounted for 
      about 65%, 20%, and 15% of the total bacteria, respectively. The mathematical 
      evaluation of experimental data reported in literature indicated that 
      heterotrophic growth in nitrifying biofilm (30-50%) and granules (30%) was 
      significantly higher than that of nitrifying sludge (15%). It was found that low 
      influent ammonium resulted in a lower availability of soluble microbial products 
      (SMP) and a slower heterotrophic growth, but high ammonium (>150 mg N L(-1)) 
      feeding would lead to purely AOB dominated sludge with high biomass-associated 
      products contained effluent, although the absolute heterotrophic growth 
      increased. Meanwhile, the total active biomass concentration increased gradually 
      with the increasing solids retention time, whereas the factions of active AOB, 
      NOB, and heterotrophs varied a lot at different solids retention times. This work 
      could be useful for better understanding of the autotrophic wastewater treatment 
      systems.
