TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Method: The method includes (A) putting culture medium (200 ml) in 500 ml cone-shaped bottle, sterilizing at 121 degrees C for 30 minutes, cooling to 45-55 degrees C, pouring in sterilized plate, cooling to room temperature, inoculating Cordyceps kyushuensis strains on inclined plane of PDA culture medium, coating with sealed membrane, and culturing at 20-30 degrees C for 7-20 days, in which the culture medium has natural pH and comprises (g/L) sucrose (20-40), peptone (5-10), yeast extract (5-10), magnesium sulfate (0.5-1), monopotassium phosphate (0.5-1), agar powder (15-20) and water (balance); sterilizing inducing culture medium at 121 degrees C for 30 minutes, cooling to 45-55 degrees C, pouring in sterilized plate, cooling to room temperature, boring on edge of activated Cordyceps kyushuensis plate colony using sterile hole puncher with diameter of 0.7 cm, inoculating strains at center of the plate of inducing culture medium, and coating with sealed membrane, in which the inducing culture medium has natural pH and comprises (%) glycerin or mannite (0.5-20), peptone (1.5-2.5), monopotassium phosphate (0.05-0.1), magnesium sulfate (0.03-0.05), agar (1.5-2) and water (balance); and putting the plate in constant-temperature tank, culturing with dispersed light (in which sporocarp primordium arises after 11 days), collecting sporocarp, venting, and drying at 40-60 degrees C; or (B) putting liquid seed culture medium (200 ml) in 500 ml cone-shaped bottle, sterilizing at 121 degrees C for 30 minutes, cooling to room temperature, inoculating Cordyceps kyushuensis strains, and culturing on rotary shaker at 150 revolutions/minute (rpm) and 20-30 degrees C for 7-20 days to obtain liquid strain, in which the liquid seed culture medium has natural pH and comprises (g/L) sucrose (20-40), peptone (5-10), yeast extract (5-10) and water (balance); splitting inducing culture medium in 500 ml cone-shaped bottle, sealing the bottle with cotton tampon, coating two layers of paper, sterilizing at 121 degrees C for 30 minutes, taking out culture medium, naturally cooling to room temperature, and inoculating liquid strain (5-10 ml) in each bottle, in which the inducing culture medium has natural pH and comprises (%) rice (30-40), glycerol or mannitol (0.5-10), monopotassium phosphate (0.3-0.4), magnesium sulfate (0.15-0.25) and water (balance), whose pH value is natural value; and putting inoculated seeds in constant-temperature culture tank, culturing at 20-30 degrees C for 8-12 days, culturing hypha under dispersed light at 16-18 degrees C and 85-95% relative humidity for 45-80 days, collecting sporocarp, venting, and drying at 40-60 degrees C.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The culture medium comprises (wt.%) (i) glycerol or mannitol (2-8, preferably 2.5-3.5), peptone (1.5-2.5), monopotassium phosphate (0.05-0.1), magnesium sulfate (0.03-0.05), agar-agar (1.5-2), and water (balance); or (ii) rice (30-40), glycerol or mannitol (1.3-7, preferably 2.7-4), monopotassium phosphate (0.3-0.4), magnesium sulfate (0.15-0.25), and water (balance).
