Method for culturing cordyceps militaris sporocarp with high-content bioactive substances

Abstract

The invention provides a method for culturing cordyceps militaris sporocarp with high-content bioactive substances, comprising the following steps: inoculating good cordyceps militaris strains after multiple repeated filtering on a culture medium with the best optimized proportion of carbon to nitrogen sources; and optimizing and culturing at different temperatures, humidity and illumination intensities at different growth periods. Through the cordyceps militaris sporocarp planted and obtained by the method provided by the invention, the contents of bioactive substances are greatly improved, and the bioactive substances mainly comprise the chemical index components of adenosine, cordycepin, cordyceps polysaccharide, cordycepic acid, SOD (Super Oxide Dlsmutase) and the like; for the cordyceps militaris sporocarp planted and obtained by the method provided by the invention, the pharmacology and drug effect are extremely similar to natural Chinese caterpillar fungus, and the contents of bioactive substances of adenosine, cordycepin, cordyceps polysaccharide and cordycepic acid are over that of the natural Chinese caterpillar fungus.

Description

Technical field:

[0001] The invention belongs to the technical field of new resource food. In particular, it relates to a method for industrialized cultivation of fruit bodies of Cordyceps militaris with high content of biologically active substances. It particularly relates to an industrialized cultivation method for increasing the content of biologically active substances in fruiting bodies of Cordyceps militaris. Background technique:

[0002] Natural wild Cordyceps sinensis is formed in a special ecological and extreme environment. It has special genes and expression products and traits, has strict polytrophy, and requires a special ecological and geographical environment in alpine regions. Therefore, the yield is very small. In 2005, the country banned the digging of wild Cordyceps, so the contradiction between supply and demand is very prominent now. In order to alleviate the contradiction between supply and demand, my country has listed the artificial cultivation of...
