AB  - The effects of Thiobacillus denitrificans combined with signal molecules on the 
      removal of sulfide and nitrate was investigated. By adding signal molecules and 
      T. denitrificans at the same, the total number of microorganisms increased, the 
      removal of sulfide and nitrate was accelerated, and an increase in nitrogen gas 
      and more stable accumulation of elemental sulfur was observed. The total number 
      of microorganisms after the reaction was detected using fluorescence in situ 
      hybridization (FISH) technique. In this experiment, the optimal concentration for 
      the stable accumulation of elemental sulfur from six concentrations of signal 
      molecules was revealed. Further, the effects of adding signal molecules, T. 
      denitrificans, and their combination were analyzed at this concentration. The 
      results showed that it was easier to accumulate elemental sulfur after the 
      addition of 1.0 mumol.L(-1) signal molecule. After adding both T. denitrificans 
      and 1.0 mumol.L(-1) signal molecules at a sulfide concentration of 200 mg.L(-1), 
      the removal of sulfide and nitrate increased to 99.8% and 96.9% at 72 h, 
      respectively, and increases in nitrogen gas and sulfur were observed. The amounts 
      of elemental sulfur and nitrogen gas reached to 59.0 mg and 80.0 mL, 
      respectively, after adding 2.5 mumol.L(-1) signal molecules at 72 h when the 
      sulfide concentration was 300 mg.L(-1). Under those conditions, the removal 
      efficiency of sulfide and nitrate reached 99.0% and 93.9%, and the production of 
      elemental sulfur and nitrogen reached 63.1 mg and 79.5 mL, respectively.
