CEO Yukiko Moriya

The flagship product of Aureo Co., Ltd. is β-glucan obtained by Aureobasidium (black yeast) fermentation. We aim to contribute to society through health and beauty by leveraging the remarkable characteristics of this product.
It has been over 20 years since our company was founded, but we still continue to find fresh new ways that Aureobasidium (black yeast) β-glucan can be used, including developments in immune research.
Also, Aureobasidium (black yeast) β-glucan has been covered by NHK news in past when research on its effects on influenza came to light. It is gaining more recognition in Japan, and around the world.
Our mission is to realize a healthier and richer society through our business, which is based upon the endless possibilities of Aureobasidium (black yeast) β-glucan.

Origin of company name

The Latin name for black yeast is Aureobasidium pullulans.
We named our company ‘Aureo Co., Ltd’ because we wanted as many people as possible to know about black yeast beta-glucan, which is obtained by culturing the Aureobasidium pullulans microorganism.
