Study on the Production of Polysaccharide from Ganoderma lucidum Mycelia in Deep-liquid Fermentation

Through biological engineering fermentation technology,making full use of the high productivity of deep-liquid fermentation,to produce G.lucidum 730 mycelia and polysaccharide in 500 L automatic stainless steel fermenter.The results were as follows,after a fermention time of 70 hours,there was no obvious vgerminate and lock like connection on the mycelia wall.There was a little mycelia dissolved with no other bacteria.The consistence of G.lucidum clump is about 30%,Extracellular Ganoderma Polysaccharide and Intracellular Ganoderma Polysaccharide is 3.5 g/L and 4.8% respectively.
