Improved mycelia and polysaccharide production of Grifola frondosa by controlling morphology with microparticle Talc
Abstract Background Mushroom showed pellet, clump and/or filamentous mycelial morphologies during submerged fermentation. Addition of microparticles including Talc (magnesium silicate), aluminum oxide and titanium oxide could control mycelial morphologies to improve mycelia growth and secondary meta...
