Alginate oligosaccharides (AOS)

Alginate oligosaccharides are carbohydrates composed of 2-10 monosaccharides connected by glycosidic bonds. Oligosaccharides play an important role in the basic life process of organisms and the occurrence and development of organisms. The development of functional oligosaccharides has become an important direction in the field of international biotechnology. Alginate oligosaccharides have low molecular weight and have strong water solubility, high stability, high safety and non-toxic physical and chemical properties. It also have many biological activities and have broad development prospects in agriculture and other fields.

Effects of alginate oligosaccharides:

Low-molecular weight alginate oligosaccharides have many biological activities, such as anti-tumor, anti-oxidation, antibacterial, growth-promoting etc., and have broad development prospects in the fields of drug development, functional food development, and agriculture.

Anti-inflammation:

Alginate oligosaccharides are rich in sources, theoretically they are good anti-inflammation substitutes for sLex, sLea and heparin oligosaccharides, and have good potential medicinal value.

Antibacterial:


	

	
Alginate oligosaccharides had strong antibacterial activity against three common aquatic pathogens Aeromonas hydrophila and Candida albicans, and showed strong antibacterial activity against Vibrio anguillarum in the late exponential phase. It provides a certain basis for marine oligosaccharides to replace antibiotics and become a new generation of safe, efficient, and non-toxic and side-effect-free feed additives for aquaculture, and has a broad prospect for development and application in aquatic feed.
	
	

	
Alginate oligosaccharides have antibacterial activity because some bacterial polysaccharide degradation products can act as toxic factors and inhibit cell growth. Alginate oligosaccharides at 10-0.3125 g/L can significantly shorten the adaptation period of bifidobacteria, and make bifidobacteria proliferate in large quantities. Therefore, alginate oligosaccharides have good application prospects in the proliferation of bifidobacteria and the development of functional health food.
	


In agriculture:


	

	
 Promoting plant growth - promoting seed germination, promoting germination.
	
	

	
Alleviating plant abiotic stress  - cold tolerance, drought tolerance, salt tolerance, heavy metal tolerance.
	
	

	
having the active effect of elicitors - stimulating the production of phytoalexin and accumulating specific defense substances.
