| Abstract: | Objective] The aim was to study the mediun optimization of sweet sorghum juice fermentation alcohol. Method]The fermentation media of Co-158 yeas were optimized for better alcohol production by sweet sorghu. The effects of different nitrogen source and inorganic salt on alcohol fermentation were studied by single factor test and orthogonal test. Result] The optimal fermentation medium was：（NH4）2SO4 6 g/L,MgSO4 6 g/L,CaCl2 10 g/L,KH2PO4 0.3 g/L.Under the optimal conditions the alcohol volume percentage could reach 9.0%. Conclusion] The study provided reference for alcohol production with sweet sorghum as material. |
