title: Microbial kinetics of Clostridium termitidis on cellobiose and glucose for biohydrogen production.
abstract: OBJECTIVE
  To determine Monod kinetics parameters (µmax, Ks, kd and YX/S) of the mesophilic H2 producer Clostridium termitidis grown on glucose and cellobiose by modeling in MATLAB.
  
  
  RESULTS
  Maximum specific growth rates (µmax) were 0.22 and 0.24 h(-1) for glucose and cellobiose respectively; saturation constants (Ks) were 0.17 and 0.38 g l(-1) respectively and the biomass yields (YX/S) were 0.26 and 0.257 g dry wt g(-1) substrate. H2 yields of 1.99 and 1.11 mol H2 mol(-1) hexose equivalent were also determined for glucose and cellobiose respectively.
  
  
  CONCLUSIONS
  The microbial kinetics of this model microorganism will enhance engineering biofuel production applications.
