Embodiment 1

[0019] The bacteria were inoculated on the slant, and the medium formula was 1.5% glucose, 1.0% corn flour, 0.5% dextrin, 1.5% bran, 0.5% yeast powder, 1.5% silkworm chrysalis powder, 1.0% peptone; 0.01% magnesium sulfate, phosphoric acid Potassium dihydrogen 0.02%; agar powder 0.8%, the rest is water, cultured at 12°C for 25 days; 1.0% bean cake powder, 0.5% yeast extract; 0.01% magnesium sulfate, 0.02% potassium dihydrogen phosphate, and the rest is water, placed on a shaker, cultured at 14°C for 8 days; then inoculated in a primary fermentation tank, cultured at 14°C 8 days, and then expand with 10 times the amount of medium, and ferment step by step until the 30-ton tank. Solid-liquid separation is carried out after leaving the tank, and the solid is dried and crushed.

Embodiment 2

[0020] Embodiment 2: the formula of fermentation medium is: glucose 1.5%, corn steep liquor 1.0%, molasses 1.5%; Silkworm chrysalis powder 1.0%, 2.0%, yeast extract 1.0%; Manganese sulfate 0.0125%, potassium chloride 0.01%, all the other are Water, the ventilation rate is 5:1. The slant culture medium and all the other steps and conditions are the same as in Example 1.

Embodiment 3

[0021] Example 3: inoculate the strains on the slope, the medium formula is: 1.0% glucose, 2.0% corn flour, 1.0% potato juice, 1.0% dextrin; 1.5% bran, 0.1% yeast powder, 3.0% silkworm chrysalis powder; Magnesium sulfate 0.01%, potassium chloride 0.01%; agar powder 0.8%, the rest is water, the fermentation medium and other steps and conditions are the same as in Example 1.

Abstract

The invention discloses a culture medium to ferment and manufacture Cordyceps sinensis mycelium, which consists of bevel culture medium and fermentation culture medium, wherein different culture mediums are adopted in different stages to ensure plain growth of the Cordyceps sinensis and equal quality of fermented and natural Cordyceps sinensis, which modifies the product quality and improves the production with certain effect. The invention supports the character of nourishment with natural Cordyceps sinensis, which is fit for industrial manufacturing need.

Description

technical field [0001] The present invention relates to a kind of Chinese Cordyceps sinensis anamorph (Latin scientific name is Cordyceps sinensis) - the Chinese cordyceps sinensis (Latin scientific name is Hirsutella sinensis) adopts industrialized fermentation to produce the production method of fermented Cordyceps sinensis fungus powder, specifically relates to its Formulation of media in industrial processes. Background technique [0002] Cordyceps sinensis is a naturally occurring rare Chinese herbal medicine, which contains mannitol, ergosterol, adenosine, cordycepic acid, cordyceps sinensis, vitamin B 12 and other active ingredients. Its nourishing and healing functions are based on ginseng and deer antler. However, natural Cordyceps sinensis has a long growth period and is distributed in alpine meadows at high altitudes. Resources are scarce, collection is difficult, and the price is very expensive. [0003] Hangzhou Zhongmei Huadong Pharmaceutical Co., Ltd. obtai...
