Construction of Wanmai-Qu solid-state fermentation system with aroma-producing yeast and its growth kinetic
A double-layer tray bioreactor was designed.Using Wanmai(peeled wheat)as the fermentation substrate and different aroma-producing yeasts as strains,the solid-state fermentation system for Wanmai-Qu was established.Meanwhile,the growth kinetics model of yeast was established based on the Logistic model.The results showed that the viable counts of Meyerozyma guilliennondii,Wickerhamyces anomalus,Kluyveromyces marxianus and Hanseniaspora uvarum in Wanmai-Qu were all above 4×109 CFU/g after solid-state fermentation for 26 h.The growth kinetics models of 4 aroma-producing strains of yeast were successfully established(R2＞0.96,P＜0.001),and the relative error between the fitted values and experimental values of the four models was less than 3％,which could well reflect the growth characteristics of the 4 aroma-producing yeasts on Wanmai.
