Problems solved by technology

And the general culture method does not take a sample and try to plant, even if increase the link of sampling and try to plant, also can only take a sample on the test tube, the effect is relatively poor
In the general culture method, the Cordyceps militaris strains are on the rice culture medium, and the growth in the early stage is vegetative growth and reproductive growth at the same time. It takes about 10-15 days for the mycelium to grow full of the rice culture medium, and in the same culture container, the fruiting body The growth of the fruit grows early and late, coupled with the competition of growth space and nutrition, it will inevitably lead to some too old and some too tender when harvesting, so it is difficult to grasp the harvesting time. The entity is relatively slender and weak

Embodiment Construction

[0007] The method for improving the production stability of Cordyceps militaris of the present invention, selects excellent bacterial classification (in test tube), introduces secondary pre-cultivation, improves the stability of Cordyceps militaris growth, and its concrete steps are:

[0008] a. Scrape the mycelium on the surface of the inclined surface, inoculate it into the liquid medium, and culture it in suspension for 2-3 days, then introduce it into the first pre-cultivation. One test tube strain can inoculate 5-8 bottles of the suspension.

[0009] b. Take samples for trial planting, and store the rest in a refrigerator at 3-5°C. The samples must be put into the refrigerator immediately after sampling, and the storage time in the refrigerator should not exceed 60 days.

[0010] c. After confirming the production performance of the strain, take out the normal suspension for sampling and inoculate it, and eliminate other suspensions. When inoculating, take 1.5-2ml of the...

Abstract

A method for increasing the production stability of cordyceps includes preculturing in the culture liquid, inoculating from a test tube to 5-8 bottles of suspension, further inoculating from one bottle to 100 bottles, and secondary preculturing. Its advantages are short period and high quality stability.

Description

technical field [0001] The invention relates to a method for improving the production stability of Cordyceps militaris. Background technique [0002] Cordyceps sinensis is an extremely precious medicinal edible fungus. In recent years, with the continuous improvement of people's living standards, the development of medical care science and the continuous expansion of the field of understanding of Cordyceps, medicines and health care products that use Cordyceps as the main raw material The development of food, beverages and cosmetics is emerging in an endless stream. Not only the demand for grass insects in the domestic market is expanding day by day, but also in international markets such as Southeast Asia, Japan, and the United States. Due to the scarcity of wild Cordyceps resources, it is not easy to excavate, and the supply is often in short supply. The price continues to rise and climb, which has doubled the price of Cordyceps. Excessive excavation has not only led to th...
