Problems solved by technology

[0007] The environmental conditions of the culture medium disclosed in the above two patent documents are still unsuitable, and it is not obvious to Coprinus comatus against miscellaneous bacteria pollution, and there is still a large amount of miscellaneous bacteria pollution in the process of growing bacteria
[0008] In summary, the Coprinus comatus culture medium still exists in the prior art, and the rate of contamination by miscellaneous bacteria remains high in the process of growing bacteria, which leads to the deterioration of the production environment, the gradual reduction of production benefits, and the normalization of the industrialization of edible fungi. development and many other issues

Abstract

The invention relates to a bacterial contamination-resistant coprinus comatus cultivation matrix and a preparation method thereof. The matrix comprises the following components: bean dregs, corncobs, lime powder, lime paste, gypsum powder, light calcium carbonate and compound fertilizer. The preparation method comprises the steps of performing pile fermentation on the bean dregs by adjusting the pH value to be not more than 3 by adopting a diluted hydrochloric acid solution, performing pile fermentation on the corncobs and the lime powder, adding the lime paste, the gypsum powder, the light calcium carbonate and the compound fertilizer, adjusting the pH value of the matrix to be not less than 11, fermenting, and adjusting the pH value to obtain the matrix. According to a formula of the matrix, the bean dregs are subjected to the pile fermentation by adjusting the pH value to be the low limit of the pH value tolerated by coprinus comatus by adding the diluted hydrochloric acid solution, the corncobs and the lime powder are subjected to the pile fermentation by adjusting the pH value to be the high limit of the pH value tolerated by the coprinus comatus, and the bacterial contamination can be effectively inhibited in a fermentation process; the purpose of resisting bacterial diseases is achieved while a novel raw material resource is opened up for coprinus comatus production.

Description

technical field [0001] The invention relates to a Coprinus comatus cultivation base material resistant to contamination by miscellaneous bacteria and a preparation method thereof, in particular to a method for respectively adjusting the extreme pH value of Coprinus comatus base material by using dilute hydrochloric acid solution and lime paste to make it resistant to contamination by miscellaneous bacteria, belonging to The technical field of edible mushroom cultivation. Background technique [0002] Coprinus comatus, scientific name (Cprinuscomalus), also known as Coprinus comatus, Prickly Mushroom, Coprinus pubescens, Coprinus grandis, etc., belongs to Fungal Phylum, Basidiomycotina, Phylomycetes, Agaricaceae, Coprinus family in taxonomy , Coprinus genus, Coprinus comatus began to be artificially cultivated in Western countries in the 1970s, and China was successfully cultivated in the 1980s. Because Coprinus comatus bags have a short growth cycle, high biotransformation ...
