Problems solved by technology

But now the wild resources of Cordyceps are limited. According to reports, every year in a certain county of Qinghai Province, during the growing season of Cordyceps sinensis, driven by huge profits, hundreds of thousands of people flock to the grasslands to excavate Cordyceps, seriously damage vegetation, plunder Cordyceps resources, and destroy the local ecological balance , resulting in soil erosion and serious land desertification; in addition, the natural Cordyceps sinensis has a long growth cycle and low yield, which is far from meeting the growing consumption demand. Because of its outstanding curative effect and high price, it leads to indiscriminate digging, resources are on the verge of exhaustion, and there is an urgent need to develop alternative products

[0023] Technical content not mentioned below can be used for reference or adopt existing technical methods:

[0024] 1. Acquisition of strains

[0025] The Taishan Cordyceps standard samples parasitic on the Lepidoptera (Lepidoptera) Pyralidae or Arctiidae (Arctiidae) in the pollution-free ecological environment in the Taishan area were extensively collected to obtain wild Cordyceps militaris fruiting bodies with good agronomic properties. Preliminary classification and identification, specimen preservation.

[0026] Using the conventional spore separation method, tissue separation method, and substrate separation method, the wild-type strains were isolated and purified, and the strains were identified and stored for future use. During the investigation process, the fresh Cordyceps militaris with thick and strong spores was taken out from the soil, put into the prepared sulfuric acid paper triangular bag, brought back to the laboratory, and put in the refrigerator (4°C) to be...

Abstract

The invention relates to a new microbiological species, the phorozoon is Paecilomyces suffultus (Petch) Samson. The method consists of inoculating the said germ to parasite body or subculture medium, cultivating them in a proper condition to obtain a yellow-while fruiting body of Cordyceps. The said germ has advantages that it is suitable for artificial culture in a large number, the effective composition content is high, the adaptive capacity for environment is strong, the production velocity of bacterium is rapid, the stress is strong, the yield rate is high, the cultivated cycle is short and the germ can not degenerate.

Description

technical field [0001] The invention relates to a new microorganism, in particular to a Taishan Cordyceps fungus and a cultivation method thereof. Background technique [0002] Cordyceps militaris, also known as Cordyceps militaris, is an entomogenic fungus that parasitizes on the pupae (worms) of various insects. It is a treasure with both food and medicine. In recent years, with the in-depth research at home and abroad, the importance of the dual functions of Cordyceps militaris for nourishing and medical treatment has been further recognized. It has been determined that Cordyceps militaris contains cordycepin, polysaccharides and superoxide dismutation substances. Cordycepin has obvious antagonistic or inhibitory effects on Bacillus subtilis, Mycobacterium avium, human nasopharyngeal carcinoma KB cells, and human epidermoid nevus. Cordycepin is also used as an inhibitor of RNA synthesis in cell research. In addition, the mycelium and spore products of Cordyceps militari...
