Abstract: The xanthan fermentation data in the stationary phase was analyzed using the black box and
the metabolic network models. The data consistency ls checked through the elemental balance
in the black box model. In the metabolic network model, the metabolic flux distribution in
the cell is calculated using the metabolic flux analysis method, then the maintenance
coefficients is calculated.

Key words: xanthan fermentation, black box model, metabolic flux analysis, maintenance coefficients
