The Science

Understanding Aureobasidium Beta Glucan

A unique polysaccharide produced by black yeast — distinct in structure, production, and immune interaction.

The Organism

Aureobasidium pullulans is a naturally occurring black yeast found in soil and plant surfaces worldwide. It produces beta glucan through controlled fermentation — no chemical extraction required.

Common Questions

Direct, evidence-based answers to the most frequently asked questions about Aureobasidium pullulans beta glucan.

See All FAQs
Q What is Aureobasidium pullulans beta glucan?
Aureobasidium beta glucan is a polysaccharide produced by black yeast (Aureobasidium pullulans) through controlled fermentation. It features β-1,3/1,6 glycosidic linkages that interact with immune receptors including Dectin-1 and complement receptor CR3. Unlike oat or barley beta glucan (β-1,3/1,4), it is not chemically extracted and retains its natural biological structure.
Q How is it different from oat or mushroom beta glucan?
The key difference lies in the molecular linkage. Oat beta glucan has β-1,3/1,4 linkages optimized for cholesterol reduction. Mushroom beta glucan shares the β-1,3/1,6 structure but requires hot water or alcohol extraction. Aureobasidium beta glucan is unique because it is produced directly by black yeast fermentation — no chemical extraction — preserving its native structure and immune receptor-binding properties.
Q Is Aureobasidium beta glucan safe for consumption?
Multiple peer-reviewed studies have evaluated safety parameters in animal and human trials. Studies show no significant adverse effects at tested doses. However, as with any bioactive compound, individuals with autoimmune conditions or those on immunosuppressive therapy should consult a physician. This site presents research findings only — not medical advice.
