Development of renewable energy from lignocellulosic biomass is very important things because of finite fossil fuel. Lignocellulose is the most abundant energy source on Earth, and provides the benefit of reducing greenhouse gas emissions by up to 86% compared with fossil fuels. Miscanthus is one of lignocellulosic biomass that can be used as feedstock for bioenergy production and has many benefits as follow: i) high yield, ii) environmentally friendly, iii) easy to grow, iv) low maintenance, v) an annual growing cycle, vi) requires no pesticides or fertilizers, vii) increases wildlife biodiversity, viii) eligible for cross compliance, and ix) long lifespan. The most important thing is to avoid the ethical concerns associated with using potential food resources. And, the simultaneous saccharification and fermentation (SSF) has been suggested as the favorable strategy to reduce the production cost of lignocellulosic bioethanol. In the present study, the potential of SSF process as a tool in the optimization of second generation bioethanol production from Miscanthus was examined. The thermostable yeast was used to overcome the difference in appropriate temperature for saccharification and fermentation. The first batch was 41℃ for the enzymatic hydrolysis and the second batch was 35℃ for the yeast fermentation. In addition, we conducted to investigate nutrient for recovering the activity of yeast.
