AB  - In this study, a fluorescence approach was used to evaluate the production of 
      soluble microbial products (SMP) in aerobic granular sludge system under the 
      stress of 2,4-dichlorophenol (2,4-DCP). A combined use of three-dimension 
      excitation emission matrix fluorescence spectroscopy (3D-EEM), Parallel factor 
      analysis (PARAFAC), synchronous fluorescence and two-dimensional correlation 
      spectroscopy (2D-COS) were explored to respect the SMP formation in the exposure 
      of different doses of 2,4-DCP. Data implied that the presence of 2,4-DCP had an 
      obvious inhibition on biological nitrogen removal. According to EEM-PARAFAC, two 
      fluorescent components were derived and represented to the presence of 
      fulvic-like substances and humic-like substances in Component 1 and protein-like 
      substances in Component 2. It was found from synchronous fluorescence that 
      protein-like peak presented slightly higher intensity than that of fulvic-like 
      peak. 2D-COS further revealed that fluorescence change took place sequentially in 
      the following order: protein-like fraction > fulvic-like fraction. The obtained 
      results could provide a potential application of fluorescence spectra in the 
      released SMP assessment in the exposure of toxic compound during wastewater 
      treatment.
