Embodiment 1

[0031] (1) Selection of Cordyceps militaris strain host

[0032] Cordyceps militaris is cultivated with cooked silkworms (the 5th instar silkworm larvae develop to the end and stop eating mulberry leaves, which are called cooked silkworms) as hosts. The mature silkworms are required to have transparent bodies and light red feces.

[0033] (2) Preparation of Cordyceps militaris strain

[0034] Add a fruiting body of Cordyceps militaris (frozen preservation or fresh fruiting body) in a good growth state to the sterile PDA slant medium, cultivate it in a dark environment at 19°C, and carry out light culture after the aerial hyphae cover the entire slope , after the aerial mycelium turns yellow completely, gently scrape out the mycelium in a sterile environment, add sterile water and grind to make a suspension of Cordyceps militaris, the concentration of the suspension of Cordyceps militaris is 0.1mg / μL (based on the mass of fresh mycelium).

[0046] (1) Selection of Cordyceps militaris strain host

[0047] Cordyceps militaris is cultivated with cooked silkworms (the 5th instar silkworm larvae develop to the end and stop eating mulberry leaves, which are called cooked silkworms) as hosts. The mature silkworms are required to have transparent bodies and light red feces.

[0048] (2) Preparation of Cordyceps militaris strain

[0049] Add a fruiting body of Cordyceps militaris (frozen preservation or fresh fruiting body) in a good growth state to the sterile PDA slant medium, cultivate it in a dark environment at 20°C, and carry out light culture after the aerial hyphae cover the entire slope , after the aerial mycelium turns yellow completely, gently scrape out the mycelium in a sterile environment, add sterile water and grind to make a suspension of Cordyceps militaris, the concentration of the suspension of Cordyceps militaris is 0.1mg / μL (Based on the mass of fresh mycelium).

[0061] (1) Selection of Cordyceps militaris strain host

[0062] Cordyceps militaris is cultivated with cooked silkworms (the 5th instar silkworm larvae develop to the end and stop eating mulberry leaves, which are called cooked silkworms) as hosts. The mature silkworms are required to have transparent bodies and light red feces.

[0063] (2) Preparation of Cordyceps militaris strain

Abstract

The invention relates to a novel method for breeding cordyceps militaris by utilizing silkworm larvae. The method comprises the steps of taking live matured silkworm as the host, vaccinating cordyceps militaris strains through an injection method, and promoting silkworm to sleep, and the vaccination attainment rate is improved; after the method is adopted, the inactivation rate of the silkworm larvae reaches 90% to 100%, and the outgrowth rate of fruiting body reaches 85% to 100%; moreover, the water-solubility protein, polysaccharide, cordycepic acid, cordycepin and adenosine of the cordyceps militaris bred by the method are higher than those of cordyceps militaris bred by silkworm chrysalis in content. The novel method for breeding cordyceps militaris by utilizing silkworm larvae has the advantages of convenience in operation, low breeding cost, good experiment repeatability and wide application prospect, and is suitable for large-scale cultivation.

Description

Technical field: [0001] The invention belongs to the field of edible fungus cultivation, and relates to a method for artificially cultivating Cordyceps militaris, in particular to a method for cultivating Cordyceps militaris with live silkworm larvae as hosts. Background technique: [0002] Cordyceps militaris, also known as Cordyceps militaris or Cordyceps militaris, is a kind of edible and medicinal fungus recognized both at home and abroad. Studies have shown that the types and contents of effective chemical components of Cordyceps militaris are the same or similar to those of Cordyceps sinensis, and have the same or similar functions on the human body. They all contain biologically active substances such as cordycepic acid, cordycepin, polysaccharides, SOD enzymes and ergosterol, It has the effects of improving immunity, anti-tumor, anti-oxidation, anti-fatigue, anti-radiation, lowering blood sugar, lowering blood fat and delaying aging (Wei Huiping, 2004). [0003] Com...
