It is also important signal molecules in plants, which can promote the growth of plants and increase the resistance of plants to diseases and insect pests.  As a professional alginate oligosaccharides manufacturer and global supplier, Shandong Jiejing Group Corporation has been specialized in manufacturing and exporting alginate oligosaccharides for 56 years. Please be rest assured to buy alginate oligosaccharides from Shandong Jiejing. Any questions or inquiry feel free to contact us by email, you will get response in one working day.

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.

Structure and Properties

Alginate oligosaccharide AOS is a small molecule obtained by enzymatic hydrolysis of sodium alginate. Its degree of polymerization is below 20. The small molecular oligosaccharide is composed of β-D mannuronic acid and α-L guluronic acid through β-1-4 glycosidic bonds. Linked carbohydrates.

The biological activity of alginate oligosaccharides is closely related to its structure. It can enhance the expression of indole synthesis genes, improve resistance to abiotic stress and bacterial diseases.

  • As a type of plant endogenous oligosaccharides, alginate oligosaccharides play the role of signal molecules in plant stress resistance and can promote plant growth. The germination rate of seeds soaked in alginate oligosaccharides increases, a well as seedling height and root length are improved. The amount of chlorophyll increases, the chlorophyll content in the leaves of the seedlings increases, the root activity is enhanced, and the effect of increasing production is obvious, and it is a stimulating factor for plant growth and development.

  • Enhance plant stress resistance, drought resistance and other stress resistance, and induce crop resistance through signal factors. After use, crops show obvious tolerance when facing harsh external environments, and the stress resistance effect is obvious.

  • Inhibit plant pathogenic bacteria, induce plant defense response, and then produce systemic resistance to make plants have disease resistance.

  • It can be used as a stabilizer for pesticides, as a molluscicide, as a fertilizer forming agent, regulator, etc., or directly as a pollution-free antibacterial agent or to produce oligosaccharide pollution-free antibacterial pesticides.

Alginate oligosaccharides (AOS) uses in agriculture

Study on Fresh-keeping Effect of AOS Postharvest Treatment on Strawberry:

After 6 days of postharvest treatment, the bad fruit rates of strawberries treated with 50ppm and 100ppm AOS were 26.67% and 31.11% lower than those of the control group respectively.

Application of Alginate oligosaccharides in plant disease resistance:

Jayaraj et al. reported that alginate oligosaccharides have a significant preventive effect on carrot leaf fungal diseases. AOS can increase the activity of peroxidase, polyphenol oxidase, and PAL enzymes, and increase the gene expression of disease process-related proteins at the transcriptional level.
