Embodiment 1

[0038] 1. Cultivate Cordyceps sinensis strains:

[0039] The applicant purchased wild fresh Cordyceps sinensis in Yushu area of ​​Qinghai in 1987, and obtained the Cordyceps strains by tissue separation method. After inspection, it was determined that this bacterial strain is the Cordyceps sinensis Mortierella bat moth strain, which is a true Cordyceps sinensis strain. In order to preserve and prevent the degradation of the strains throughout the year, the healthy cell propagation method was used to expand the strains and the strains have been preserved to this day. Cultivation of Cordyceps first cultivates the slant mother species and liquid bacteria for infecting the insect body.

[0040] 1. Inclined mother seed medium: agar 20g, glucose 30g, peptone 5g, silkworm chrysalis powder 5g, yeast extract 1g, potassium dihydrogen phosphate 1g, magnesium sulfate 0.5g, auxin 1ml, sterile water or tap water 1000ml, pH value nature.

[0041] Production method: Boil silkworm chrysalis...

Abstract

A technique for culturing cordyceps by insect includes such steps as collecting fresh wild cordyceps, tissue separation to obtain its bacterial strain, reproduction, culturing slant strain and liquidbacteria, choosing host insect or host insect surrogate, spraying bacterial liquid for infecting the host insect, and culturing in the condition stimulating the wild environment. Its advantages are low cost and high effect.

Description

[0001] The technical field [0002] The invention relates to a new technology for cultivating Cordyceps sinensis with insects. The invention belongs to the bioengineering technical field of artificially infecting insects with Cordyceps fungus to cultivate and grow fruit bodies of Cordyceps sinensis. Background technique [0003] At present, some units use biological fermentation engineering to cultivate Cordyceps mycelium and make Cordyceps oral liquid or capsules. There are also some units that use rice medium or semi-synthetic medium such as agar, glucose, peptone, etc. to infect the fruiting body (grass) of Cordyceps fungus growth without insect body. The nutrients contained in the above-mentioned Cordyceps mycelium and fruiting body (grass) without insect body are not as good as the Cordyceps sinensis with complete insect body in medicinal and edible health functions, and the production of Cordyceps mycelium and fruiting body without insect body ( Grass) are expensive. ...
