AB  - Maximizing methane production while maintaining an appreciable level of process 
      stability is a crucial challenge in the anaerobic digestion industry. In this 
      study, the role of six parameters: the type of immobilizing supports, loading 
      rate, inoculum levels, C:N ratio, trace nutrients concentrations and mixing rate, 
      on methane production were investigated under thermophilic conditions (55 +/- 1 degrees C) 
      with synthetic substrate medium. The immobilizing supports were Silica gel, Sand, 
      Molecular Sieve and Dowex Marathon beads. A Taguchi Design of Experiment (DOE) 
      methodology was employed to determine the effects of different parameters using 
      an L(16) orthogonal array. Overall, immobilizing supports influenced methane 
      production substantially (contributing 61.3% of the observed variation in methane 
      yield) followed by loading rate and inoculum which had comparable influence 
      (17.9% and 17.7% respectively). Optimization improved methane production by 153% 
      (from 183 to 463 ml CH(4)l(-1)d(-1)).
