Establishment and Analysis of the Fermentation Medium Model of Phellinus igniarius

Abstract:

In order to optimize the Phellinus Linteus fermentation medium, the wheat flour content, the rice bran content, the KH2PO4 content and the MgSO4 content have been regarded as the independent variables and the fermentation yield has been considered as the dependent variable. The quadratic regression orthogonal rotating combination design method has been adopted to build the model for Phellinus Linteus fermentation medium formula. And this model has been also analyzed in this paper. The results have shown that the most important factors which affect the fermentation yield include the content of rice bran, the flour content, the KH2PO4 content and the MgSO4 content. There exists the significant interaction between the content of rice bran and the MgSO4 content, promote each other’s using. The optimal fermentation medium formula of Phellinus Linteus are: the wheat flour content of 5.16%, the rice bran content of 1.38%, the KH2PO4 content of 0.094%, the MgSO4 content of 0.054% The experimental results have shown that the model fits well with the actual situation and the credibility is higher.
