Culture medium achieving high-effective cultivation of flammulina velutipes through bio-magnetic effect and preparation method thereof

Abstract

The invention discloses a culture medium achieving high-effective cultivation of flammulina velutipes through a bio-magnetic effect. The culture medium includes following components, by weight, bamboo vinegar, gelatin / hyaluronic acid composite micro-spheres being controllable in appearance, xylitol, porous silicon dioxide micro-spheres with nano Fe3O4 supported thereon, silkworm chrysalis powder, Muyu stone powder, porcine plasma protein powder, bran, corncob, peanut shell, cotton seed hull, orange residue, yeast, protease and a proper amount of magnetized water. The culture medium for flammulina velutipes is prepared from the silkworm chrysalis powder and the like materials, thereby achieving proportion of nitrogen source and carbon source in different types and further increasing the activity of lignin-degrading enzyme of flammulina velutipes. Meanwhile, by means of the porous silicon dioxide micro-spheres with the nano Fe3O4 supported thereon, the magnetized water and the composite yeast supported by the gelatin / hyaluronic acid composite micro-spheres, the influence on activity of the lignin-degrading enzyme of the flammulina velutipes is effectively improved. During the fermentation process, magnetic stirring is carried out so that the raw materials are completely decomposed and the culture medium is balanced in nutrition.

Description

technical field [0001] The invention relates to the field of edible fungus culture medium, in particular to a medium for realizing the high-efficiency cultivation of Flammulina velutipes through biomagnetic effects and a preparation method thereof. Background technique [0002] As a high-quality edible fungus, Flammulina velutipes is widely loved by consumers; the quality of Flammulina velutipes is affected by the combination of different nitrogen and carbon sources on the activity of Flammulina velutipes degrading lignin enzymes, and the biomagnetic effect has a certain impact on enzyme activity. It is worth studying to improve the high-efficiency cultivation of Flammulina velutipes by increasing the enzyme activity.

Problems solved by technology

[0003] 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
