Researchers from Northeast Forestry University Report Details of New Studies and Findings in the Area of Industrial Crops and Products (Semi-solid-state Fermentation of Polygonum Cuspidatum Roots By a Novel Endophytic Fungus Penicillium Rubens...).

Researchers from Northeast Forestry University in Harbin, China have published a study on the semi-solid-state fermentation of Polygonum cuspidatum roots using a novel endophytic fungus called Penicillium rubens. The study found that this fermentation method improved the yield of resveratrol, a high-value natural compound with various pharmacological activities. Under optimal conditions, the yield of resveratrol in the fermented roots was 19.18 times higher than in the unfermented control. The study also showed that the fermented roots exhibited higher antioxidant and antibacterial activities. The researchers concluded that this cost-effective fermentation method has potential applications in the pharmaceutical, nutraceutical, and cosmetic industries. [Extracted from the article]
