Abstract

The invention provides a method for producing liquid edible fungus strains by using wastes from a cordyceps militaris culture medium. The method comprises the steps that the culture medium wastes generated during cordyceps militaris planting are smashed and stirred to be uniform by adding water, after gelatinization with boiling water, cooling is conducted, and the pH value is adjusted; the smashed wastes are mixed with alpha-diastasum diastace and glucoamylase and then stirred, and after a double-enzyme digestion reaction, an enzymatic reaction is stopped; cooling is conducted, water is replenished, the pH value is adjusted, papain is added, and an enzymatic reaction is carried out; after the enzymatic reaction, solid-liquid separation is conducted to remove residues, and a culture mediumwaste hydrolysis fluid is obtained; the hydrolysis fluid is diluted with water, after sterilization and fermentation, the diluted culture medium waste hydrolysis fluid is directly used for productionof edible fungi. The method has the advantages that being decomposed by cordyceps taishanensis exoenzyme, the wastes are suitable for culture raw materials of other macro fungi, and the wastes are converted into culture mediums in the fermentation industry and successfully used for production of the liquid strains of aurcularia auricula or lentinula edodes or hericium erinaceus or pleurotus citrinopileatus. The method has the advantages that the raw materials are low in cost and easy to obtain, the preparation process is simple, the wastes are changed into valuable things, and the method conforms to environmental protection concepts.

Description

technical field [0001] The invention belongs to the field of recycling and reuse of agricultural production waste resources, and relates to a method for producing edible fungus liquid strains by using waste culture medium of Cordyceps militaris, in particular to a method for producing fungus, shiitake mushrooms and Hericium erinaceus by using waste culture medium of Cordyceps militaris The method of edible fungus liquid strains such as fungus or yellow elm mushroom can realize the reutilization of the culture medium waste of Cordyceps militaris through biotransformation. Background technique [0002] Cordyceps militaris is a traditional medicinal and edible fungus, rich in nutrients. It is a fast-growing industry with a large scale. Shenyang City, Liaoning Province is the place where Cordyceps militaris was discovered and the birthplace of artificial cultivation of Cordyceps militaris. After more than 30 years of planting and development, Shenyang has an annual production c...
