Embodiment 1

[0049] (1) Medium

[0050] Recipe: 840 parts of millet, 42 parts of glucose, 0.10 part of sodium selenite. Add 100ml of water to sodium selenite to make an aqueous solution.

[0051] Add 2000ml of water and glucose to the casserole, heat to boil, add millet and sodium selenite aqueous solution, stir well, cover the pot, stir with a shovel after 3 minutes, continue heating and boiling for 20 minutes, and keep stirring until the millet becomes solid Turn off the fire when it is in the posture, and let it stand at room temperature. Divide the culture medium into small pieces with a shovel, divide them into bottles, seal them with kraft paper blocks, and wrap them tightly with cotton rope. Put the culture medium in the pressure cooker, a total of 2 layers; place the inoculation needle in a large test tube and seal it, put kraft paper in an envelope and seal it, and wrap them with cotton rope; keep the mouth of the test tube upward, and place it in the gap of the culture medium; ...

Embodiment 2

[0059] (1) Medium

[0060] Recipe: 800 parts of millet, 35 parts of glucose, 0.07 part of sodium selenite. Add 100ml of water to sodium selenite to make an aqueous solution.

[0061] Dissolve glucose in 2000ml water and heat to boiling, then add millet and sodium selenite, continue heating and boiling until the millet becomes solid, stop heating, let it cool to room temperature, and sterilize for later use.

[0062] (2) Inoculation

[0063] The mycelium of I. catalis was cultured in a ventilated environment with a relative humidity of 45% at 22°C as a strain, and was taken out for use after the culture was complete.

[0064] (3) Dried

[0065] Put the cultured mycelium and culture medium together in a drying container, and dry them twice to form mycelium blocks. On the first day, bake at 110°C for 5 hours; on the second day, bake at 80°C for 6 hours.

Embodiment 3

[0067] (1) Medium

[0068] Recipe: 900 parts of millet, 50 parts of glucose, 0.14 parts of sodium selenite. Add 100ml of water to sodium selenite to make an aqueous solution.

[0069] Dissolve glucose in 2000ml water and heat to boiling, then add millet and sodium selenite, continue heating and boiling until the millet becomes solid, stop heating, let it cool to room temperature, and sterilize for later use.

[0070] (2) Inoculation

[0071] The mycelium of I. catalis was cultured in a ventilated environment with a relative humidity of 50% at 18°C ​​as a strain, and was taken out for use after the culture was complete.

[0072] (3) Dried

[0073] Put the fully cultivated mycelium and medium together in a drying container, and dry them twice to form mycelium blocks. On the first day, bake at 95°C for 5 hours; on the second day, bake at 90°C for 6 hours.

Abstract

The invention relates to a selenium-rich isaria feline culture substance and a culture method thereof. The selenium-rich isaria feline culture substance solves the problem of organic selenium addition in isaria feline. 800 to 900 parts of millet, 35 to 50 parts of glucose and 0.06 to 0.14 part of sodium selenite are prepared into a culture medium; then, isaria feline strains are inoculated onto the culture medium; after the culture is completed, hypha and the culture medium are jointly put into a baking container to be baked into hypha blocks in two steps. In the fungus cultivation process, the inorganic selenium is added into the culture medium; through microbial fermentation, the inorganic selenium is changed into organic selenium capable of being easily absorbed by the body; the physiological activity and the absorption rate of the selenium can be improved; the toxicity can also be reduced. When people take artificial cordyceps sinensis, the selenium element supplementation si increased, so that the selenium supplementation function of the artificially cultured cordyceps sinensis is added.

Description

technical field [0001] The invention relates to a culture of I. catalis and a cultivation method thereof, in particular to a culture of I. felis which is added with trace element selenium and a cultivation method thereof. Background technique [0002] Cordyceps sinensis is a nourishing precious Chinese herbal medicine, sweet in nature and warm in taste. The function nourishes the lung and kidney, resolves phlegm and relieves cough. It can be used for "deficiency" symptoms such as chronic cough, dyspnea due to deficiency, postpartum weakness, impotence and coldness. Cordyceps sinensis mainly contains components such as cordyceps sinensis, cordycepic acid, adenosine and polysaccharides; Cordyceps sinensis can inhibit the growth of streptococcus, Bacillus anthracis and other bacteria, and is an anti-cancer active substance, which has effects on the endocrine system and nervous system of the human body. Good regulating effect; Cordyceps acid can change the microcirculation of ...
