Eichhornia crassipes is macrophyte that originated in Amazon in South America. Eichhornia crassipes is utilized for purification of water or as a feedstock of producing useful materials and feed of animals. Eichhornia crassipes is one of the potential biomass for production of bioethanol, because of it grows fast and it is not edible [1]. For the production of bioethanol, most effective pretreatment method of water hyacinth is alkaline/oxidative pretreatment (A/O pretreatment) using NaOH/H2O2 solution [2]. In this study, to increase the production of bioethanol we optimized A/O pretreatment condition and hydrolysis condition. For hydrolysis of biomass, different commercial enzymes were used. A/O pretreatment was treated in different NaOH/H2O2 concentration and reaction temperature. Enzymatic hydrolysis was performed under different enzyme concentrations and enzyme ratios. After ethanol fermentation using Saccharomyces cerevisiae KCTC 7928, the concentration of glucose and ethanol was analyzed by HPLC with RI.
