Embodiment 1

[0024] Embodiment 1: the cultivation method of a kind of selenium-enriched Cordyceps militaris of the present invention, comprises the following steps:

[0025] S1. Activation and cultivation of strains: inoculate the strains of Cordyceps militaris in the activation medium for strains, and cultivate at a constant temperature of 21°C, humidity of 60-85%, and shading for 7 days; the activation medium for strains includes the following qualities Percentage of components: wheat 10%, wheat bran 4%, soybean 8%, sucrose 1%, peptone 1.5%, potassium dihydrogen phosphate 0.8%, triamine citrate 1.2%, selenium-enriched yeast powder 3%, the balance for water.

[0026] S2, liquid bacterial culture: select the product with better activity in step S1, inoculate it in the liquid bacterial culture medium, and shake it at a constant speed under the shaking speed of 120-150 times / min to carry out shaker culture 5-7 The liquid culture medium includes the following components by mass percentage: 1...

Embodiment 2

[0031] Example 2: The difference from Example 1 is:

Abstract

The invention discloses a cultivation method of selenium-enriched cordyceps militaris, and belongs to the technical field of cordyceps militaris cultivation methods. Comprising the following steps: strain activation culture: a strain activation culture medium comprises the following components: wheat, wheat bran, soybeans, cane sugar, peptone, monopotassium phosphate, triamine citrate, selenium-enriched yeast powder and water; culturing a liquid strain, wherein a liquid strain culture medium comprises the following components: soybean meal, cane sugar, peptone, monopotassium phosphate, vitamin B12, selenium-enriched yeast powder, an oak leaf extract and water; selenium-enriched culture of sporocarp, wherein a selenium-enriched culture medium of sporocarp comprises the following components in percentage by mass: wheat, wheat bran, cane sugar, molasses, peptone, monopotassium phosphate, triamine citrate, selenium-enriched yeast powder, calcium amino acid chelate and water. Through the synergistic effect of organic selenium in the culture medium formula, absorption and accumulation of selenium elements are induced, and the selenium content of the cordyceps sinensis can be increased while residue harm caused by addition of inorganic selenium is avoided.

Description

technical field [0001] The invention belongs to the technical field of Cordyceps militaris cultivation methods, and in particular relates to a cultivation method of selenium-enriched Cordyceps militaris. Background technique [0002] Cordyceps militaris (Cordyceps militsris) is an insect-borne fungus belonging to the subphylum Ascomycota and Ergotaceae, also known as Cordyceps militaris. Under the circumstance that Cordyceps sinensis cannot be commercialized artificially, the market is extremely scarce, and the price remains high, Cordyceps militaris has become the focus of development in various industries such as fungi, medicine, health food, and biology at home and abroad for many years. [0003] Selenium is an indispensable trace element in the human body, which has the physiological functions of anti-oxidation and anti-aging. At the same time, selenium deficiency will lead to decreased immunity, Keshan disease, Kashin-Beck disease, cardiovascular and cerebrovascular di...
