Abstract:
The capacities of the Ganoderma lucidum strains for production of Ganoder Lucidum Polysaccharide (GLP) by submerged fermentation were examined and Ganoderma lucidum G22 was shown to be the best one. The fermentation conditions for GLP production by Ganoderma lucidum G22 were also studied and the optimal fermenting temperature, shaking rate, the initial pH value of the medium and fermenting time were 28 ℃, 180 r/min, 6.0 and 144 h, respectively, under which the yield of GLP was improved to 2.315 g/L.
