Abstract
The technical conditions of fuel ethanol production by sweet sorghum stalk and the comprehensive use of the production residue were studied.Besides,the optimum technical conditions of fuel ethanol production by sweet sorghum stalk juice fermentation were determined as follows: the brix of sorghum stalk juice as 20°Bx(sugar content was 17.8 %),10 % inoculation quantity,pH value was 4.5,and alcohol concentration could reach up to above 10.2 % after 48 h fermentation with residual sugar content less than 1 %.
