Problems solved by technology

[0010] It can be seen that in the existing disclosed Cordyceps militaris cultivation technology, the carbon-to-nitrogen ratio, especially the dynamic carbon-to-nitrogen ratio, has not been paid enough attention to. The compatibility of nutrients and other aspects, while ignoring the internal factors and external conditions necessary for the growth of Cordyceps militaris, thus affecting the output of Cordyceps militaris, and at the same time, affecting the quality of Cordyceps militaris to a large extent

Embodiment 1

[0020] Embodiment 1: In the preparation of culture medium, the weight share of its various fractions is: select rice 41%, dry product silkworm chrysalis 2.5%, peptone 0.25%, inorganic salt 0.25%, glucose 0.6%, surplus is water. After calculation, the carbon content is 0.74%, and the nitrogen content is 0.034%. Inject the liquid Cordyceps militaris into the container containing the above-mentioned medium under aseptic conditions. During the vegetative growth period, the ambient temperature of the strain is kept at about 16°C, and it is protected from light within the first five days, and then given scattered light irradiation for the next five days. ; In the late growth stage, the ambient temperature should be kept at about 20°C, and the relative humidity should be 85%. At the same time, 0.5% glucose solution is sprayed on the surface of the medium to supplement the carbon source.

Abstract

The invention relates to a kind of culture medium for cultivating insect grass and the preparation method. The culture medium mainly contains slabby admixture which is composed by aging corn and chrysalis. The weight ratio in the admixture follows this. Carbon is 0.4%-1.0%, while nitrogen is 0.02%-0.05%. The surroundings will change when bacterium grown up in alimentation period of growth and anaphase by this method, so the technique for preventing and diffusing light is needed. Thus, the content of sterine, nucleoside and organic acid in the insect grass is the same to or more than content in the wild. At the same time, the output of sporocarp can increase by 10%-15%.

Description

Technical field: [0001] The invention relates to a medium for cultivating Cordyceps militaris and a method for cultivating Cordyceps militaris using the medium. Background technique: [0002] Cordyceps militaris, also known as Cordyceps militaris, is the model species of the genus Cordyceps. Cordyceps militaris and Cordyceps sinensis are very similar, both are the combination of animals and plants, so they have the same or similar drug components. Because Cordyceps contains more than 10 kinds of sterols and more than 10 kinds of nucleoside compounds, 6 kinds of dipeptide compounds, polysaccharides of Cordyceps, multivitamins and inorganic salts, etc., and contains more than 20 kinds of amino acids and nucleic acids, these rich and balanced nutrition The ingredients are especially suitable for those with low immune function, hyperlipidemia and patients with physical weakness after illness. Its unique antibacterial, antiviral, anticancer, and improving the body's ability to r...
