Objective:The metabolic flux balance model of L-histidine synthesis by Corynebacterium glutamicum TL1105 was established and the stoichiometric analysis of L-histidine biosynthesis was conducted.Methods:Based on this model, the practical metabolic flux distribution in the middle and late period with sodium citrate and without sodium citrate were determined with the linear program planted in MATLAB softwere.Results:The results show that the metabolic flux channeled to hexose monophosphate pathway(HMP) and L-...
