Alginate oligosaccharides enhanced Triticum aestivum L. tolerance to drought stress
Plant Physiology and Biochemistry, 2013Alginate 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 ...

Design, synthesis and biological evaluation of alginate oligosaccharide derivatives
Bioorganic & Medicinal Chemistry LettersTo discover new potential drug for acute kidney injury (AKI), a series of novel alginate oligosaccharide derivatives were synthesized and characterized by the spectroscopic analysis. By using the controlled experimental method, the target compounds were evaluated preliminarily for therapeutic activity in AKI. The results demonstrated that compounds 2a,

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 ...

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 ...

Alginate lyase which was purified from the fermentation solution of marine bacteria Pseudomonas sp. HJZ216 was applied to hydrolyze algae alginate. Six oligosaccharides, including di- and trisaccharides, were isolated and purified through anion exchange chromatography. The oligosaccharide structures were elucidated based on electrospray ionization-mass

To achieve the cost-effective alginate oligosaccharides production, we have developed a novel rational design strategy that optimized capture behavior, orientation movement and hydrogen bond interaction of substrate in alginate lyase ALYI1. This approach led to S56D and G258Q advantageous variants balancing the trade-off challenge, particularly S56D ...

Alginate is mainly a linear polysaccharide composed of randomly arranged β-D-mannuronic acid and α-L-guluronic acid linked by α, β-(1,4)-glycosidic bonds. Alginate lyases degrade alginate mainly adopting a β-elimination mechanism, breaking the glycosidic bonds between the monomers and forming a double bond between the C4 and C5 sugar rings to produce ...
