Effects of Different Carbon-nitrogen Ratios on Submerged Culture of Ganoderma capense

The effects of different carbon nitrogen ratios on submerged culture of Ganderma capense were studied, using the method of submerged culture fermentation. The results showed that the dry weight of mycelium pllets ascended with the increase of carbon content, when the content of nitrogen fixed The trend of the pH changes was “ascending→descending→stable. When the content of carbon is fixed, the trend of the pH change presented a “double peak shape The effects of different carbon nitrogen ratios on the submerged culture of Ganderma Capense were obvious The quantity of mycelium and the pH of the ferment solution were studied, and the culture properties of the ferment solution and mycelium pellets were observed. The results showed that the proper ratio of carbon nitrogen was between 20∶1～40∶1 And the most suitable ratio was 30∶1 In this treatment, the final pH was 3 4, the number of mycelium pellets/10mL was 113, and the dry weight of mycelium/dL was 683 4 mg The ferment solution was clear The mycelium pellets were almost in the same diameter.
