Since the feedstock cost is one of the major obstacles in commercialization of bioethanol production, various feedstocks have been investigated. In this study, P. densiflora and Solidago altissima L. were tested as new alternative feedstocks for the bioethanol production. They are fast growing plants.
P. densiflora and Solidago altissima L. were pretreated with sodium hydroxide. The pretreated sample was enzymatically hydolyzed using 15 FPU/g-glucan enzyme loading. Compositional analysis such as sugars and ethanol was carried out by YSI-7100. The pretreatment conditions were optimized in terms of reaction temperature, reaction time, and sodium hydroxide concentration.
