The distillers' grains fermentation was studied, which was from ethanol fermentation of sweet sorghum stalk. The factors such as temperature, concentration, inocula, pH etc. were analysis. The results showed the optimal temperature was 55°C, the optimal weight concentration of distillers' grains was 3.3%, the amount of inocula was 1.5%, and the pH should be adjusted before fermentation. Under this condition, the maximum biogas production was 3710mL/d and appeared in the 9th day. The overall length of the fermentation period was 32d, and the biogas production rate was up to 509mL/gTS. The results could provide a theoretical basis for the fermentation of biogas production from distillers' grains.
