Antioxidant activity of Alginate Oligosaccharides (AOS) from Sargassum sp. for Improving the Cutaneous Wound Enclosure in Zebrafish (Danio rerio) [PDF]
Jurnal Kelautan Tropis, 2021 Sargassum sp. classified as brown seaweed which is known as an alginophyte (alginate producer). Alginate has undergone a depolymerization process called alginate oligosaccharides (AOS) and has been shown to have antioxidant activities to increase wound ...

Preparation and structure elucidation of alginate oligosaccharides degraded by alginate lyase from Vibro sp. 510 [PDF]
Carbohydrate Research, 2004 Alginate that was purified from the fermentation solution of marine bacteria Vibro sp. 510 under specific reaction conditions was hydrolyzed by alginate lyase. Seven oligosaccharides, including di-, tri- and tetrasaccharides, were isolated through low-pressure, gel-permeation chromatography (LP-GPC) and semipreparative strong-anion exchange (SAX) fast ...

Detection of Alginate Oligosaccharides from Mollusks [PDF]
Bioscience, Biotechnology, and Biochemistry, 2006 We attempted in this study to detect alginate oligosaccharides (AO) from mollusks. The samples used were digestive organs taken from turban shells and abalones which commonly ate brown algae. High-performance liquid chromatography (HPLC) and negative-ion electrospray ionization (ESI) quadrupole time-of-flight (Q-TOF) mass spectrometry (MS) analyses ...
