[0048] Example 1
[0049] (1) Take the front end of the vigorous mycelium on the PDA comprehensive medium and inoculate it in a 100 mL Erlenmeyer flask containing Pleurotus ostreatus liquid medium. The volume of the bottle is 50 mL, and each bottle receives 3 to 4 0.5 cm clumps. Incubate in the dark at 25°C for 5-11 days; pick out the mycelium under aseptic conditions and absorb the water with sterile filter paper to obtain fresh Pleurotus ostreatus mycelium.
[0050] (2) Take fresh Pleurotus eryngii and Pleurotus eryngii mycelium, and carry out enzymolysis at the ratio of 0.1g wet weight and 1ml enzyme solution. Among them, the enzymatic hydrolysis temperature of Pleurotus eryngii mycelium protoplast is 34℃ and the enzymatic hydrolysis time is 3h. The enzymatic hydrolysis temperature of Pleurotus eryngii mycelium protoplasts is 34°C, and the hydrolysis time is 2h. The enzymatic hydrolysis of Pleurotus eryngii mycelium according to the present invention: 2ml 0.6mol / L MgSO 4 ·7H 2 O...
