doi:10.7525/j.issn.1673-5102.2016.01.023

Abstract

Abstract: We studied the effects of various factors on the yield of ethanol from enzymatic hydrolysate of Tara fiber residues by the single factor experiment, and then optimized ethanol production technology by orthogonal experiments. The optimum conditions were the ratio of sodium alginate-yeast of 1∶2 g·g^-1, substrate sugar concentration of 30%, the amount of yeast of 1.5 g, and fermentation time of 120 h, with the yield of ethanol of 83.68%.

Key words: fiber residues, fermentation, ethanol, immobilized yeast
