Enzymatic Hydrolysis of Alginate to Produce Oligosaccharides by a New Purified Endo-Type Alginate Lyase [PDF]

Marine Drugs, 2016
Enzymatic hydrolysis of sodium alginate to produce alginate oligosaccharides has drawn increasing attention due to its advantages of containing a wild reaction condition, excellent gel properties and specific products easy for purification. However, the efficient commercial enzyme tools are rarely available.

Antihypertensive Effects of Sodium Alginate Oligosaccharides.

Journal of the agricultural chemical society of Japan, 2001
Two types of alginate oligosaccharides (Na-AO and K-AO) were prepared by cleavage of alginate polysaccharide with alginate lyase. In this study, the effects of these oligosaccharides on blood pressure of spontaneously hypertensive rats (SHRs) were investigated. In the Na-AO experiment, Na-AO and NaCl groups were fed a normal diet (CE-2, Clea Japan Inc.)

Modulating the Gut Microbiota with Alginate Oligosaccharides In Vitro

Nutraceuticals, 2022
Alginate oligosaccharides (AOS) are non-digestible carbohydrates from brown kelp. As such, they are dietary fibers and may have prebiotic potential. Therefore, we investigated the capacity of gut bacteria to utilize AOS with single-strain cultures and as a complex bacterial community.

Alginate Lyase and Its Applications in Alginate Oligosaccharides Production

Food Reviews International
In recent years, marine resources become strategic resources and attract widespread attention due to their unique physiological and physiochemical properties. Alginate, a prominent marine polysaccharide, is derived from the cell walls of brown algae and certain bacteria.

Alginate Oligosaccharide and Gut Microbiota: Exploring the Key to Health

Nutrients
Alginate oligosaccharide (AOS), a degradation product of alginate derived from marine brown algae, has attracted significant attention due to its potent ability to modulate gut microbiota and enhance human health. This review aims to systematically introduce current evidence on the interactions between AOS and gut microbial communities, focusing on how

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 ...

Macroalga-Derived Alginate Oligosaccharide Alters Intestinal Bacteria of Atlantic Salmon [PDF]

Frontiers in Microbiology, 2019
Prebiotics are substrates intended to sculpt gut microbial communities as they are selectively utilized by the microorganisms to exert beneficial health effects on hosts. Macroalga-derived oligosaccharides are candidate prebiotics, and herein, we determined the effects of Laminaria sp.-derived alginate oligosaccharide (AlgOS) on the distal intestinal ...

Review on Preparation, Separation and Characterization of Alginate Oligosaccharide

Shipin gongye ke-ji, 2022
Alginate oligosaccharide (AOS) is a kind of low molecular polymer, which is composed of 2~25 monosaccharides (mannuronic acidandguluronic acid) by glycoside bond. Compared with alginate, AOS, which has the characteristics of low viscosity, good water solubility, easy absorption and strong stability, meanwhile which has many biological activities, such ...

Production of Alginate Oligosaccharides (AOS) as Prebiotic Ingredients through by Alginate lyase enzyme

Jurnal Pengolahan Hasil Perikanan Indonesia, 2017
Prebiotics is indigestible foods that can not be digested but can stimulate the growth and activity of bacteria in the digestive tract effecting human health. Alginate oligosaccharides (AOS) can be used as a source of prebiotic. That compounds can be produced enzymatically by cutting long chain alginates using alginate lyase.
