Article Synopsis
  • Researchers isolated a new mutant of Grifola frondosa, M270, using cosmic radiation to enhance exopolysaccharide (EPS) production.
  • M270 produced a thicker EPS layer and higher yields in fermentation, achieving 10.3 g/L of EPS and 17.9 g/L of dry mycelia biomass over 204 hours.
  • The water-soluble EPS fraction, EP1, was identified as a heteroglycan-protein complex, exhibiting tumor growth inhibition in mice, suggesting potential therapeutic applications.

Inonotus sanghuang, an authentic "Sanghuang" mushroom used in traditional Chinese medicine, is known to possess important pharmacological activities. In this study, we aimed to optimize the liquid fermentation medium for I. sanghuang mycelial production and to determine the effects of two-stage cultivation (shake and static) on the yield of total flavonoids, total phenolics, and polysaccharides, as well as the antioxidant activities of I.

The immunomodulatory effect of polysaccharides extracted from mycelia of the medicinal mushroom Antrodia camphorata in submerged culture was studied in 100 specific pathogen-free (SPF) chickens. The chickens were randomly divided into 2 groups (50 per group). For the treated group, each kilogram of SPF chickens was fed 5 mg of A.

Seven natural products, including one new sesquiterpenoid (eudesm-1β, 6α, 11-triol, compound 1), one ergosta -4, 6, 8(14), 22-tetraen-3-one (compound 2), four polyphenols (compounds 3, 4, 5, 6), and one pyrone (3-hydroxy-2-methyl-4-pyrone, compound 7) were isolated from cultures of Phellinus ignarius by column chromatography. The detailed structure of compound 1 was determined using a combination of one- and two-dimensional nuclear magnetic resonance, mass spectrometry and infrared spectroscopy. The antiviral activity of these compounds against H5N1 influenza A virus was investigated using an MTT colorimetric assay system in Madin-Darby canine kidney cells.
