: Pylaiella littoralis was collected in the Chuuk lagoon of the Federated States of Micronesia (FSM). The FSM has a variety of coral reef ecosystems, which provide essential materials, such as minerals, vitamins, essential amino acids, for marine organisms. In this study, the antioxidant activities of ethanol and enzymatic extracts of P. littoralis were evaluated by measuring their scavenging activities on DPPH free radical, Alkyl radical, hydroxyl radical and cell viability. The enzymatic extracts were hydrolyzed to prepare water soluble extracts by using five carbohydrate degrading enzymes (AMG, Celluclast, Termamyl, Ultraflo, and Viscozyme) and five proteases (Alcalase, Flavourzyme, Kojizyme, Neutrase, and Protamex). As a result, the enzymatic extracts prepared by Flavourzyme, Ultraflo, and Kojizyme exhibited the greatest effects in DPPH free radical, alkyl radical scavenging activity and cell viability. Also, these enzymatic extracts had a higher antioxidant effect then commercial antioxidants in DPPH free radical and Alkyl radical scavenging activity. This study suggests that P. littoralis might be a useful source of natural antioxidants for the development of dietary supplements. 통계 이 연구에서 실험값은 SPSS package program의 paired t-test로 검정하여 통계 값을 구했으며, 모든 실험값은 평 균 ± 표준편차(Mean ± standard deviation)로 나타내었다.

“…The purpose is not only for the prevention and treatment of various diseases caused by oxidative damage, but also for improving the shelf life of food products (Yang, Jiang, et al, 2009;Zhao, Kan, Li, & Chen, 2005). Polysaccharides possess a wide range of biological properties, such as immunomodulation , anti-cancer (Jiang, Wang, Liu, Gan, & Zeng, 2011), antiageing (Song, Zhang, Zhang, & Wang, 2010), hyperglycemic , and anti-inflammatory (Kang et al, 2011) activities. Plants, particularly those used as traditional Chinese medicines, contain high amounts of natural polysaccharides that have been identified as free radicals or active oxygen scavengers (Wang & Luo, 2007).…”

A marine bacterial strain that degraded fucoidan from Ecklonia cava was isolated from seawater. The crude fucoidanase of this strain efficiently degraded fucoidan at pH 8 and 50℃. The crude enzyme hydrolyzed 7.1% (w/w) fucoidan within 24 hrs from an 1% (w/v) fucoidan solution and produced oligosaccharides by endo-type hydrolysis as the reaction products. The results of 16S rRNA gene sequence analysis and biochemical tests permitted a tentative identification of strain SB 1493 as a Pseudoalteromonas species.Key words : Fucoidan, fucoidanase, hydrolysis, marine bacterium, Pseudoalteromonas *Corresponding author *Tel：+82-51-999-5629, Fax：+82-51-999-5458 *E-mail : jhsohn@silla.ac.kr This is an Open-Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/3.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.
