Researchers successfully revived a beneficial fungus called Acremonium sp. MEP2000 that had lost its effectiveness through repeated cultivation by adding birch bark powder and medicinal mushroom powder to its growth medium. When used to treat the medicinal fungus Inonotus obliquus (chaga), this revitalized fungal culture dramatically improved the growth and production of healthy bioactive compounds like polysaccharides and triterpenoids. This breakthrough offers a practical solution for large-scale production of medicinal fungi with enhanced therapeutic potential for treating cancer, diabetes, and inflammatory conditions.
