Batch Kinetics and Modelling of the Fermentation Process of Ganoderma applanatum Mycelia

摘要

This experiment explored the kinetic process of the fermentation of Ganoderma applanatum, and concluded kinetic models to describe it using the SPSS for windows software. During the fermentation process, the two sorts of polysaccharides: EPS, PPS could be analysed using Luedeking-Piret equation and the regrassion equations could be duduced respectively as follow: P=0.901X + 1.103 and P=0.552X + 0.477; besides, the correlation between the dry weight of mycelia and time could be analysed using Logistic equation then the regrassion equation was: y=(5.121/ 1 + 0.317e-0.998x). The parameters that could significantly affect the yield of polysaccharides were determined, then based on the regression analysis some regrassion equations were concluded: EPS=0.015T -0.350; EPS=0.010T + 1.094PPS + 45.401OP - 4.470; PPS=-0.412Q + 4.608.
