Abstract

The invention belongs to the field of edible fungi cultivation, and particularly relates to a culture method for improving contents of cordyceps militaris hypha and cordycepin in silkworm chrysalis cordyceps. The method includes cultivation of cordyceps militaris hypha and cultivation of silkworm chrysalis cordyceps. The cultivation of cordyceps militaris hypha is prepared by performing culture activation in a solid culture base and cultivating liquid culture in a liquid culture base, wherein the solid culture base and the liquid culture base include 0.083-0.81% of trace element composition by weight; the trace element composition is selected from one or more of ferric sulfate tetrahydrate, zinc sulfate octahydrate, blue copperas, manganese sulfate monohydrate, sodium cobalt dehydrate; the technical scheme disclosed in the invention is simple in method, and high in efficiency.

Description

technical field [0001] The invention relates to the field of Cordyceps militaris cultivation, in particular to a cultivation method for increasing the content of cordycepin in Cordyceps militaris mycelium and silkworm Cordyceps militaris. Background technique [0002] Cordyceps militaris is the type species of Ascomycota, Hypocreaes, Cordycepsaceae and Cordyceps. The English scientific name is Cordyceps militaris, also known as Cordyceps militaris, Cordyceps militaris, etc., and it is also called Cordyceps militaris in some areas. It is distributed worldwide, and the number of natural resources is very small. In 1950, German scientist Cunningham observed that the insect tissue parasitized by Cordyceps militaris was not perishable, and then isolated an antibacterial substance, 3'-deoxyadenosine, and named it Cordycepin. It is a complex composed of two parts, the sclerotium (that is, the grass part, also known as the fruiting body) and the sclerotia (that is, the corpse of th...
