Abstract: In order to research the effects of pH and inorganic salt on liquid fermentation of Antrodia camphorate, different fermental initial pH values including KH2PO4 and without KH2PO4, and different inorganic salts were arranged. The results indicated that Antrodia camphorate grows well under the condition of neutrality partial to acidity, while it grows slowly under the conditions of neutrality and alkalinity. And Antrodia camphorate grows well if KH2PO4 has been added in the culture medium. In addition, the requirements for different inorganic salts of Antrodia camphorate growth are different; the demand for K salt is large, while Na salt, Fe salt, Mg salt and Cu salt are little. Therefore, pH values and inorganic salts have effects on liquid fermentation of Antrodia camphorata.

Key words: Antrodia camphorata, liquid fermentation, inorganic salt, pH
