摘 要: 微生物发酵动力学模型绝大多数都是非线性的,参数回归难度大,而SAS(statistical analysis system)软件中有专门的非线性拟合版块,能够非常方便地得出准确可信的结果。结合实例运用SAS软件成功拟合出常见微生物发酵动力学模型中的参数。结果表明:用SAS软件拟合结果准确可信,方法简单,可以广泛应用于发酵动力学建模过程中的非线性拟合。
关 键 词: 发酵工程;SAS软件;非线性回归;发酵动力学;模型

Abstract: Most of dynamic models for microbial fermentation are so non-linear that the regression of model parameters is difficult to obtain. SAS software can easily calculate accurate and credible results with a special non-linear fitting module. In this paper, the SAS program was used to estimate the parameters of kinetics model. The results show that the fitting results are credible and accurate. So this method can be widely used in the fermentation kinetics of modeling.
Key words: fermentation engineering; SAS software; non-linear regression; fermentation kinetics; model
