Recently, Sargassum horneri, which has been introduced in large quantities to the west and south coasts of Korea, belongs to brown macroalgae and has high potential as a biomass for biofuel production. Therefore, in this study, the effect of salinity on the hydrolysis process was examined for the S. horneri. As a result of analyzing the ash of the unwashed sample, about 73% of the ash was found to be salts. And 96.0% of the total salt was removed by 3 repeated washing. The production of reducing sugars according to the hydrolysis method was 27.95 and 35.25 mg/g-biomass (4.1– 4.4% of hydrolysis efficiency), respectively in unwashed and washed samples by hydrothermal treatment, 37.72 and 61.71 mg/g-biomass (5.9–7.2% of hydrolysis efficiency) by enzyme treatment, and 100.49 and 138.91 mg/g-biomass (15.7– 16.1% of hydrolysis efficiency) by hydrothermal–enzyme sequential treatment, consequently, compared to the unwashed sample, it was possible to obtain 1.26–1.64 times higher reducing sugar in the washed sample. Especially, salinity in the sample has a significant effect on the bio-hydrolysis process.

최근 우리나라 서·남해안에 대량 유입되고 있는 괭생이모자반은 갈조류로서 바이오연료 생산용 바이오매스로서의 잠 재성이 높다. 이에 본 연구에서는 괭생이모자반을 대상으로 가수분해 공정에 미치는 염분의 영향을 검토하였다. 미세척 시료의 회분을 분석한 결과, 회분의 약 7 3%가 염분으로 나타났으며, 3회 반복 세척으로 총 염분의 96.0%가 제거되었다. 가수분해 방법에 따른 환원당의 생산량은, 수열처리에 의해 미세척시료 및 세척시료에서 각각 27.95 및 35.25 mg/gbiomass( 가수분해 효율 4.1–4.4%), 효소처리에 의해 3 7 .72 및 61.71 mg/g-biomass(가수분해 효율 5.9–7.2%), 수열–효소 순차 처리에 의해 100.49 및 138.91 mg/g-biomass(가수분해 효율 15.7–16.1%)로, 미세척시료와 비교하여 세척시료에서 1.26–1.64배 높은 환원당을 얻을 수 있었다. 특히 시료 중 염분은 생물학적 가수분해 공정에 뚜렷한 영향을 미쳤다.
