| Abstract: | Objective To achieve the optimum conditions of L-iso- leucine fermetation.Method Being based on the theory of metabolic control fermentation,the influence of several major components in fermentation medium on the L-iso- leucine fermentation was studied by means of the rotation composite design of quadratic regression.Using MATLAB software package the optimal fermentation medium proportions were obtained.The conditions of shake-flask fermentation were studied by experiments of one factor.Result Under the optimun conditions, 21.12 g·L -1 L-iso- leucine would be produced.Conclusion The optimun control of the fermentation conditions are very important to L-iso- leucine fermentation. |
