Alginate derived functional oligosaccharides: Recent developments, barriers, and future outlooks

Carbohydrate Polymers, 2021
Alginate is a biopolymer used extensively in the food, pharmaceutical, and chemical industries. Alginate oligosaccharides (AOS) derived from alginate exhibit superior biological activities and therapeutic potential. Alginate lyases with characteristic substrate specificity can facilitate the production of a broad array of AOS with precise structure and

Alginate Oligosaccharides: Production, Biological Activities, and Potential Applications

Comprehensive Reviews in Food Science and Food Safety, 2019
Abstract Alginate, a group of polyuronic saccharides, has been widely used in both pharmaceutical and food industries due to its unique physicochemical properties as well as beneficial health effects. However, the potential applications of alginate are restricted because of its low water solubility and high ...

Alginate oligosaccharides: Enzymatic preparation and antioxidant property evaluation

Food Chemistry, 2014
Alginate oligosaccharides (AOs) prepared from alginate, by alginate lyase-mediated depolymerization, were structurally characterized by mass spectrometry, infrared spectrometry and thin layer chromatography. Studies of their antioxidant activities revealed that AOs were able to completely (100%) inhibit lipid oxidation in emulsions, superiorly to ...

Alginate oligosaccharides enhanced Triticum aestivum L. tolerance to drought stress

Plant Physiology and Biochemistry, 2013
Alginate oligosaccharides (AOS) prepared from degradation of alginate is a potent plant elicitor. Hydroponic experiments were carried out to investigate the mechanism of AOS on improving Triticum aestivum L. resistant ability to drought stress. Drought model was simulated by exposing the roots of wheat to polyethylene glycol-6000 (PEG-6000) solution ...

In vivo prebiotic properties of alginate oligosaccharides prepared through enzymatic hydrolysis of alginate

Nutrition Research, 2006
Abstract To investigate the prebiotic potential of alginate oligosaccharides (AOS), prepared through enzymatic hydrolysis of alginate polymer, the effects of AOS on bacterial growth were studied. In vitro studies showed that the numbers of bifidobacteria or lactobacilli were greater than those in control medium when they were cultured in the medium ...

Elucidation of degradation pattern and immobilization of a novel alginate lyase for preparation of alginate oligosaccharides

International Journal of Biological Macromolecules, 2020
Alginate lyases are important enzymes to prepare alginate oligosaccharides for industrial applications and elucidating the degradation pattern of alginate lyases is essential for expanding their applications. Herein, we cloned and expressed AlyPL6, a novel member of polysaccharide lyase family-6 (PL6) with high activity from Pedobacter hainanensis NJ ...
