Abstract

Addition of Ca2+, Mg2+, Zn2+ in fermenting liquid could increase liquor yield and reduce obviously resi-dual total sugar in the solution. The experiments indicated that the optimum fermentation conditions for early nonglutinous rice to produce ethanol were as follows: temperature at 32 ℃, pH value as 4, and 120 h fermentation time. Under such conditions, alcohol content reached 9.3 %v/v, the percentage of total residual sugar achieved 1.08 %,and liquor yield of starch increased to 53.64 %. (Tran. by YUE Yang)
