Various biomass ( X ), product ( P ), and substrate ( S ) rate equations are considered in order to synthesize a general xanthan fermentation model from literature data. Analytical forms that provide reasonable descriptions for the X , P , and S behaviors reported by Moraine and Rogovin are shown to be the logistic equation, the Luedeking–Piret equation a modified Luedeking‐Piret equation, respectively. The autonomous logistic equation allows the serial evaluation of parameters for all thee equations, rather than a simultaneous determination required by nonautonomous models.
