Abstract

The invention relates to a method for processing fungal contamination in a cordyceps militaris culture process. According to the method, the culture medium surface generating fungal contamination in the culture process is covered by river sand absorbed with fungicide. The processing method provided by the invention has the advantages that the operation is simple and convenient, raw material resources are wide, the cost is low, and the fungal contamination in the cordyceps militaris culture process can be conveniently and fast processed. The cordyceps militaris fruit bodies obtained after the processing have high yield and high quality, so the processing method provided by the invention has wide application prospects.

Description

technical field [0001] The invention relates to the field of cultivation of Cordyceps militaris, in particular to a treatment method for fungal pollution in the cultivation process of Cordyceps militaris. Background technique [0002] Cordyceps militaris (L.Fr) Link, also known as Cordyceps militaris, Cordyceps militaris, belongs to Ascomycota, Pyrenomycetes, Sphaeriales, Clavicipitaceae, Cordyceps (Fr.) Link) fungi. Cordyceps militaris is the type species of the fungus of the genus Cordyceps, and it is mostly parasitic on the larvae and pupae of various lepidopteran insects in nature. [0003] In recent years, many studies have shown that the chemical composition and pharmacological effects of artificially cultivated Cordyceps militaris are similar to those of Cordyceps sinensis, but the price is far lower than that of Cordyceps sinensis. Therefore, the development and application of Cordyceps militaris has a great potential market. [0004] The current large-scale produc...
