Improved mycelia and polysaccharide production of Grifola frondosa by controlling morphology with microparticle Talc.

Our findings revealed that the presence of Talc significantly changed the polysaccharide production and sugar compositions/percentages in mycelial and exo-polysaccharides by affecting mycelial morphology and polysaccharide-biosynthesis related enzymes activities of G. frondosa.
