The investigation of fermentation conditions for the repeated batch bioethanol production from domestic corn (Gangdaok) and the value estimation as Distiller’s Dried Grains with Solubles (DDGS) of fermentation by-product
In this study, the fermentation conditions of the repeated batch process were investigated for the commercialization of bioethanol production from corn (Gangdaok) as domestic material. Also, the value as feedstuff of Gangdaok fermentation by-product was evaluated in comparison with USA corn (Ambrosia), which is a widely used feedstock. In order to carry out the repeated batch process of Gandaok, various fermentation conditions were examined. With the purified glucoamylase using and 1 g/L urea supplement, a series of the repeated batch operations was successfully carried out. The final ethanol concentration, the ethanol yield, and the volumetric productivity were attained to 85 g/L, 90%, and 1.77 g/L‧h, respectively. Furthermore, the DDGS of Gangdaok contained more essential amino acids (21.1 mg/g) than Ambrosia. The results showed that Gangdaok has potential economic advantages if applied to the bioethanol and feed industries.
