[Objective]To screen the optimum medium of Ganoderma lucidum liquid fermentation. [Method]Effect of different carbon sources on mycelial growth of G. lucidum submerged fermentation,biomass and polysaccharide content were studied. [Result] The biomass of fermented G. lucidum mycelium from corn flour hydrolyzate was the largest,followed by corn flour,glucose-corn flour,sugar-corn flour,maltose-corn flour, glucose-maltose and sucrose. Ganoderma lucidum polysaccharide content followed the trend of maltose-corn flour > glucose-corn flour > corn flour > corn flour hydrolyzate > glucose. [Conclusion]Taking all factors into consideration,the liquid fermentation of corn powder was chosen as the most excellent culture medium for Ganoderma lucidum liquid fermentation.
