Abstract:
The model equations of the production phase of rHSA fermentation were derived on the base of both elemental balance and metabolic balance, then the unknown parameters of the model were estimated by multivariable optimization. The possible reasons of discrepancy of production rate between different period of fermentation were discussed. The model could preferably described the relations between different macroscopic reaction rates of the process and keys for the high-efficiency expression of HAS were deduced.
