The third generation energy from seaweed as biomass can solve environmental and energy issues. In this study, the effective pretreatment and saccharification methods for common seaweeds such as Undaria pinnatifida, Laminaria japonica, Hizikia fusiforme, Sargassum fulvellum using physical, chemical and biological methods were evaluated for bioethanol production. The seaweeds were obtained from Gijang fisheries market in Busan and dried in sunlight or hot-air. The dried seaweeds after milling were pretreated and saccharified by the acid hydrolysis. The optimal acid hydrolysis method for the highest yields was determined as follows: 10% seaweed powder, 0.2% hydrochloric acid (HCl), heat treatment at 121℃ for 15min, agitation at 200 rpm for 30 min and neutralization by sodium hydroxide (NaOH). The physical properties of the saccharified products such as salinity, reducing sugar content and viscosity were evaluated. From these results, the optimal physical properties of seaweed saccharification were determined for bioethanol production.
