Aureo’s beta-glucan is a unique beta-glucan produced by a black yeast fungus called Aureobasidium. When black yeast fungi are cultivated under special conditions, they produce a gel-like substance around themselves. The liquid contains β-glucan with the bonding form
β -1,3-1,6 as the main component. This β-1,3-1,6 glucan is the substance that has been the focus of much attention.

Aureo’s black yeast (Aureobasidium) culture is produced by a unique strain of black yeast that Aureo possesses.
Aureo has obtained patents around the world for the proprietary fungus itself, its production method, compositions using the fungus, and even its uses.
