The stoichiometric matrix of a simplified metabolic network in Bacillus Subtillis was contructed from the flux balance equations, which were used for reconciliation of the measured rates and determination of the inner metabolic rates. Thus more reliable results of the true and empirical maintenance coefficients were obtained. The true maintenance coefficient is linearly related to the specific growth rate and changes with the P/O ratiol. The neasured biomass yield of adenosine triphosphate (ATP) is also linearly related to the P/O ratio. 相似文献

Analysis of Data on Xanthan Fermentation in Stationary Phase Using Black Box and Metabolic Network Models 下载免费PDF全文
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. 相似文献

With the xanthan synthesis in Xanthomonas campestris as an example, two methods for metabolic flux analysis of overdetermined system, the experimental data error minimization method and the equation error minimization method, are compared from their mathematical basis, rationality of the results and the easiness of computation. The results show that the experimental data error minimization method is appropriate in metabolic flux analysis of overdetermined system. 相似文献
