Various biomass (X), product (P), and substrate (S) rate equations are investigated 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, and a modified Leudeking-Piret equation, respectively. The autonomous logistic equation allows the serial evaluation of parameters for all three equations, rather than a simultaneous determination required by nonautonomous models. 22 references.
