Patent ID: 8722056

Claim:
A method for producing Cordyceps sinensis fermentation product comprising: (a) inoculating a plate culture comprising solid nutrient medium with at least one strain of Cordyceps sinensis and incubating the inoculated plate culture at about 18° C. to about 28° C. for about 4 to 8 days; (b) inoculating a first seed culture comprising liquid nutrient medium with at least a portion of the inoculated plate culture from step (a) and incubating the first seed culture at about 18° C. to about 28° C. for about 2 to 4 days; (c) inoculating a second seed culture comprising liquid nutrient medium with at least a portion of the inoculated plate culture from step (b) and incubating the second seed culture at about 18° C. to about 28° C. for about 2 to 3 days; (d) inoculating a fermentation culture comprising liquid nutrient medium with a least a portion of the incubated seed culture from step (c) and incubating the fermentation culture at about 18° C. to about 28° C. for about 1 to 3 days; and (e) recovering the Cordyceps sinensis fermentation product from the incubated fermentation culture of step (d), wherein the nutrient media in steps (a) through (d) each comprise: about 0.001% to about 0.01% (w/w) copper and about 0.0003% to about 0.003% (w/w) selenium.
