The Bioethanol for use as a liquid fuel by fermentation of renewable biomass as an alternative to petroleum is important from the viewpoint of global environmental protection. After fermentation, also Dried Distiller Grain with Soluble(DDGS) which is very useful as feed is obtained as a byproduct. The objective of this work is to evaluate ethanol productivity of Gangdaok(domestic corn) and DDGS using low-temperature pretreatment cost efficient process compared to a pressure pretreatment process. First, conditions are optimized for low-temperature pretreatment process. It was found that at 98℃ the reaction time was 1.5h. According to the fermentation results, it shows almost same ethanol productivity as the low-temperature pretreatment process and the pressure pretreatment process. Also, as a result of DDGS, Gangdaok has more essential amino acid (21.1mg/g) than that of Ambtosia (USA corn), which is a widely used materials as feedstock. To conclude, it means the one excels in economy and value of feedstock than the others.
