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 ...
