Alginate oligosaccharides (AOS) is functional oligosaccharides obtained from alginate (alginic acid) through a certain cleavage reaction. The degree of polymerization is generally 2-10.
The alginate oligosaccharide (AOS) provided by WELLYOU uses the alginate lyase enzyme activity produced by synthetic biology technology to prepare the functional substance alginate oligosaccharide. Enzymatic hydrolysis of alginic acid (seaweed polysaccharide) is the key technology for the preparation of alginate oligosaccharides, and the fermentation of Bacillus subtilis is used to produce alginate lyase.
Functions of alginate oligosaccharides (AOS):
- Activate the immune system with salicylic acid and jasmonic acid, which can resist bacteria and viruses.
- The control effect of rice blast disease is over 77%. The control effect of rice smut is over 69%. And the control effect of sheath blight is over 55%.
- Induce plants to synthesize ABA (abscisic acid content increased by 5 times) and JA (jasmonic acid), enhance stress resistance, mature earlier, and go on the market earlier.
- Induce plants to synthesize IAA (increase the auxin content by 8 times), take root and germinate quickly, and grow quickly.
- Increase fertilizer efficiency and reduce fertilizer damage; increase drug effect and reduce drug damage.
Compound ability of (AOS)：
- pH: Can accept strong acid-base compound pH 3-10
- Stability: acceptable high temperature above 150 degrees Celsius
- It can compound with calcium and magnesium, without flocculation and precipitation.
