We investigated to improved glucose conversion yields from brown algae Sargassum sagamianum by high pressure steam process . It was found that sargassum sagamianum should consisting of polysaccharides, alginate, laminaran and cellulose, when used for bioethanol production. The marine Sargassum sagamianum was hydrolyzed in a compressed cell at 100~180℃ and 1~10 bar for 8min by using only water. The optimal pretreatment condition was determined as 180℃ and 10 bar for 8min, having 7.3(% w/w) and 2.1(% w/w) of glucose and xylose conversion yields, respectively. The sargassum sagamianum was hydrolyzed in a 180℃ temperature by 1% sulfuric acid pretreatment obtained glucose yield as 4.8(% w/w), xylose yield as 1.8(% w/w). High pressure steam process could be obtained for higher yields than 1% sulfuric acid process, it thought that the impact of the expansion of the interior cell of brown algae. These results implys that high pressure process by using only water could be used to efficiently hydrolyze Sargassum sagamianum, which results would help to increase the hydrolysis yield for marine algae.
