Efficient oudemansiella radicata culture medium with propolis being antibacterial and nutrient substances and preparation method therefor

Abstract

The present invention discloses an efficient oudemansiella radicata culture medium with propolis being antibacterial and nutrient substances. The culture medium comprises the following components in parts by weight: macroporous thermally-degradable water-soluble polyvinyl alcohol microspheres, porous ultra-high-strength activated carbon microspheres, porous chitosan microspheres, rice roots, perilla oil cakes, germinated brown rice, castor oil, Hedysari polysaccharide, ionic liquid emulsified propolis and yeast. According to the culture medium provided by the present invention, porous ultra-high-strength activated carbon microspheres, porous chitosan microspheres and ionic liquid emulsified propolis are used to prepare the modified latex which is used as nutrient and antibacterial substances added into the culture medium, so that nutritive and antimicrobial effects of the culture medium are improved, thereby achieving natural and environmentally-friendly features. Macroporous thermally-degradable water-soluble polyvinyl alcohol microspheres are used to adsorb the loaded yeast for fermentation, so that the fermentation rate is effectively adjusted; decomposition of the fermentable substrate is promoted; nutrients of the culture medium are more abundant, more balanced and more convenient for absorption and utilization by the oudemansiella radicata; and a basis is provided for efficient cultivation of the oudemansiella radicata.

Description

technical field [0001] The invention relates to the field of edible fungus culture medium, in particular to a high-efficiency culture medium for rhizome mushrooms using propolis as a dual substance of antibacterial and nutrition and a preparation method thereof. Background technique [0002] Long root mushroom belongs to Basidiomycota, Agaricaceae, and Agaricaceae. It is the top grade of edible fungi. It has a delicate texture, crisp and delicious handle, rich in protein, amino acid, fat, carbohydrates, vitamins and trace elements, and has high edible value. It is of great significance to realize the high-efficiency cultivation of rhizome mushrooms. [0003] Propolis is known as "purple gold" in Europe. It contains older flavonoids, terpenes, and various organic acids. It has significant antibacterial and antiviral biological active ingredients. Its active ingredients can inhibit the growth of bacteria through tissue cell differentiation and destroy cell membranes. And the ...

Problems solved by technology

[0004] The micropores of the microspheres with a porous structure cover the entire microsphere and go deep into the center from the surface. When used as a carrier, it has the characteristics of many adsorption sites, large specific surface area and strong adsorption capacity, which can change the load. Object solubility, release ability and other characteristics are often used as carriers for slow-release fertilizers; in the preparation process of high-efficiency submerged fermentation medium for edible fungus cultivation, the decomposition and fermentation of medium raw materials directly determine the quality of the medium, and then Determine the effect of using gold in cultivation; the control of related enzymes and fermentation bacteria activity is the key and difficulty in the preparation of high-efficiency submerged fermentation medium. At present, there is no porous structure microsphere as the control of related enzymes and fermentation bacteria activity in the production process of the medium. According to reports, but according to the large specific surface area of ​​porous microspheres, it is conducive to the adhesion of a large number of cells, the transport of nutrients, the discharge of metabolites and the interaction between cells, which should be used in enzymes and fermentation. control of bacterial activity
