AB  - This work presents a simplified mathematical model able to predict the 
      performance of a microbial fuel cell (MFC) for the cathodic dechlorination of 
      2,4-dichlorophenol (2,4-DCP) operating at different cathode pH values (7.0 and 
      5.0). Experimental data from previous work were utilized for the fitting of the 
      model. The MFC modelled consisted of two chambers (bioanode and abiotic cathode), 
      wherein the catholyte contained 300 mg L(-1) of 2,4-DCP and the anolyte 
      1000 mg L(-1) of sodium acetate. The model considered two mixed microbial 
      populations in the anode compartment using sodium acetate as the carbon source 
      for growth and maintenance: electrogenic and non-electrogenic biomass. 2,4-DCP, 
      its intermediates of the reductive process (2-chlorophenol, 2-CP and 
      4-chlorophenol, 4-CP) and protons were considered in the model as electron 
      acceptors in the electrogenic mechanism. The global process rate was assumed to 
      be controlled by the biological mechanisms and modelled using multiplicative 
      Monod-type equations. The formulation of a set of differential equations allowed 
      to describe the simultaneous evolution of every component: concentration of 
      sodium acetate in the anodic compartment; and concentration of 2,4-DCP, 2-CP, 
      4-CP, phenol and chloride in the cathode chamber. Current production and 
      coulombic efficiencies were also estimated from the fitting. It was observed that 
      most of the organic substrate was used by non-electrogenic mechanism. The 
      influence of the Monod parameters was more important than the influence of the 
      biomass yield coefficients. Finally, the model was employed to simulate different 
      scenarios under distinct experimental conditions.
