Method for producing mycelia of Antrodia camphorata through deep liquid state fermentation

The invention relates to the field of fermentation engineering, in particular to a method for producing mycelia of Antrodia camphorata through deep liquid state fermentation, which comprises the following steps of strain slant culture, seed strain culture and fermentation culture; during the step of seed strain culture, the stains obtained through the slant culture in step one are further cultured to obtain secondary seed strains by liquid shaking culture, enlarging culture after liquid shaking culture, primary seed strain culture and secondary seed strain culture; during the fermentation culture, the secondary seed strains obtained in step two are transferred to a fermentation tank filled with a fermentation culture medium to implement deep liquid fermentation to obtain the mycelia of Antrodia camphorate. The method for producing mycelia of Antrodia camphorata through deep liquid state fermentation is different from common laboratory preparation methods, has the advantages of short period, high yield, high content of biological active substances, simple technique, controllable process and low cost, and is suitable for industrially producing high quality mycelia of Antrodia camphorata in large scale.
