1️⃣ Introduction to Alginate Oligosaccharide

Alginate Oligosaccharide (AOS) is a low-molecular-weight bioactive compound derived from brown seaweed (Laminaria Japonica). It possesses antimicrobial, antioxidant, immune-boosting, and plant growth-promoting properties, making it highly valuable in food, agriculture, pharmaceuticals, and biotechnology​.

Alginate oligosaccharide is produced from natural sources kelp with relatively low molecular weight, is composed of β-D-mannuronic acid (M) and α-L-guluronic acid(G) .It’s the natural algae oligosaccharides.

Alginate oligosaccharide (AOS), produced from alginate by alginate lyase-mediated depolymerisation, is a potential substitute for antibiotics and possesses growth-enhancing effects.

The oligosaccharide OligoG, an alginate derived from seaweed, has been shown to have anti-bacterial and anti-biofilm properties and potentiates the activity of selected antibiotics against multi-drug resistant bacteria.

The ability of OligoG to perturb fungal growth and potentiate conventional antifungal agents was evaluated using a range of pathogenic fungal strains.

Alginate is a linear long-chain molecule which is irregularly linked by 1,4-mannuronic acid (M) and 1,4-guluronic acid (G), and its functional oligosaccharide obtained by a certain cleavage reaction.

For brown algae oligosaccharides. Alginate oligosaccharide is a light yellowish brown powder that is soluble in water and has strong stability.

At Chibio Biotech, we offer Food-Grade and Agriculture-Grade Alginate Oligosaccharide to meet various industry needs.
