Summary
This research compared different production methods for obtaining medicinal compounds from the mushroom Poria cocos, showing that growing the fungus in liquid culture (fermentation) produces higher amounts of beneficial compounds than traditional cultivation methods. This finding could lead to more efficient and sustainable production of this important medicinal mushroom.
Impacts on everyday life:
• More affordable access to medicinal mushroom products through improved production methods
• Reduced environmental impact by eliminating need for pine tree resources in cultivation
• Faster production times meaning better supply to meet growing market demand
• Potential for new mushroom-based fragrances and essential oils
• More standardized and reliable production of medicinal compounds
Background
Poria cocos is an important medicinal and edible fungus well known in East Asia. Its main active components are water-soluble polysaccharides (WPS) and triterpenoids. Due to growing market demand, long cultivation periods, and pine trunk consumption during cultivation, alternative production methods need investigation.
Objective
To compare the content and composition of polysaccharides, triterpenoids, and essential oils between fermented mycelia and cultivated sclerotium of P. cocos to evaluate fermentation as an alternative production method.
Results
The WPS and triterpenoids in mycelia were several times higher than in sclerotium. WPS content in mycelia was 4.02-fold higher than sclerotium. Total triterpenoid content in mycelia was 8.36%, which was 9.98 times higher than sclerotium (0.84%). 62 compounds were identified in the essential oils, with linalool and methyl phenylacetate being the main fragrances in common between fermentation media and sclerotium external layer.
Conclusion
Fermentation is an effective alternative method for producing P. cocos mycelia and useful secondary metabolites including polysaccharides, triterpenoids, and essential oils. The higher yields of active compounds in fermented mycelia make this an attractive production approach compared to traditional cultivation.
