Abstract

The invention relates to a method for culturing germanium-enriched cordyceps mycelium and belongs to the technical field of pharmacognosy. The method comprises performing strain culture on a test tube slant, namely strain activation, liquid seed culture in a triangular flask, liquid culture in a seeding tank, fermentation culture in a fermentation tank, plate and frame filtration, hot air circulation and drying and smashing to obtain powdery germanium-enriched cordyceps militaris. The method has the advantages of simple operation, short culture period, high mycelium yield, no pollution or waste and high organic germanium content and has the function of germanium supplement.

Description

technical field [0001] The invention relates to a method for cultivating germanium-rich Cordyceps militaris mycelium, belonging to the technical field of pharmacognosy. Background technique [0002] Cordyceps militaris (L.) Link, also known as Cordyceps militaris, and Cordyceps militaris, belongs to Fungi, Ascomycota, Pezizomycotina, and Faecalimycetes (Sordarimycetes), Hypocreales, Clavicipiaceae, and Cordyceps (Fr.) Link] are the type species of fungi of the genus Cordyceps. Cordyceps militaris is distributed all over the world. It is an entomogenous fungus and one of the medicinal fungi. Forms fungal structures with composite morphology of worm (zombie sclerotium) and grass (mycosoma). Modern research shows that: Cordyceps militaris contains many biologically active substances such as cordycepin, cordycepic acid, polysaccharides, nucleosides, sterols, etc.; it has a variety of significant physiological functions on the human body, such as enhancing immunity, regulating ...
