A kind of method for cultivating Cordyceps militaris stroma in liquid

Abstract

The invention relates to culture of edible-medicinal fungi, and in particular relates to a liquid culture method for cordyceps militaris stroma. The liquid culture method for cordyceps militaris stroma is that cordyceps militaris strains are inoculated into a culture medium to be cultured. The liquid culture method for cordyceps militaris stroma comprises the steps of culturing mycelium, culturing sporocarp, etc. With the adoption of the liquid culture method for cordyceps militaris stroma, the technical problems of long production cycle, high energy consumption, high potential risk and the like in the prior art can be solved; the liquid culture method for cordyceps militaris stroma has the advantages that the production cycle is reduced, the contents of effective ingredients of cordyceps militaris stroma are increased, the growth conditions are easily controlled, and the industrial production can be carried out conveniently.

Description

technical field [0001] The invention belongs to the cultivation of edible and medicinal fungi, in particular to a method for cultivating Cordyceps militaris in liquid. Background technique [0002] Cordyceps militaris is a model species of Ascomycetes subphylum, Ergotaceae, Ergotaceae, Cordyceps, also known as Cordyceps militaris, Cordyceps militaris, Cordyceps and so on. Worldwide distribution of natural resources is very small. It is a complex composed of two parts, the sub-seat (that is, the grass part) and the sclerotia (that is, the dead body part of the insect). Traditional Chinese medicine believes that Cordyceps enters the two meridians of the lung and kidney, which can not only nourish the lung yin, but also nourish the kidney yang. The only traditional Chinese medicine that can balance and regulate Yin and Yang at the same time. Modern medicine believes that its unique pharmacological effects are derived from containing cordycepin and cordyceps polysaccharide. ...

Problems solved by technology

[0006] 2. Due to the wide range of raw materials such as rice, the quality is difficult to control, and there are often many food safety hazards (such as pesticide residues, heavy metals, excessive microorganisms, etc.) in the production of Cordyceps sporozoites from environmentally polluted raw materials; Only spring and autumn when silkworm chrysalis are produced), high contamination rate of inoculation, low yield of finished products, etc.

[0007] 3. Although the addition of various formulations of nutrient solutions to the solid medium can promote the growth of Cordyceps militaris, at the same time, the random addition of multiple chemical components in the nutrient solution also increases the probability of exogenous drug contamination, which will directly affect the effective substances of Cordyceps militaris Quality of ingredients (eg, cordycepin, etc.)

It is worth mentioning that Chen Guoqing et al., in the invention patent "Method for Artificially Cultivating Fruiting Body of Cordyceps militaris" with the application number 93105056.1, mentioned the method of inoculating the liquid medium of Cordyceps militaris to obtain the fruiting body. However, in The claims and examples did not further provide specific technical processes, control parameters and production effects. It can be understood that the inventor only gave the concept of liquid culture of Cordyceps militaris fruiting bodies, and did not have specific production techniques and methods.
