Efficient culture medium capable of effectively increasing protein content of pleurotus ostreatus and preparation method therefor

Abstract

The present invention discloses an efficient culture medium capable of effectively increasing a protein content of pleurotus ostreatus. The efficient culture medium comprises the following components in parts by weight: 2-3 parts of an alginate microsphere; lotus-type porous apple pomace ultrafine powder, bean cakes; wood chips; potato starches; hydroxylpropyl chitosan; a bioactive ferment lysate, and a growth promotion modulator. According to the invention, bean cakes and rapeseed cakes are used and fermented to prepare the pleurotus ostreatus culture medium so that such nutritive substances as abundant nitrogen and carbon sources are provided for the pleurotus ostreatus, thereby facilitating formation of the pleurotus ostreatus protein. Meanwhile, a nutrient-fortified growth regulation composite agent is added so as to facilitate absorption and utilization of nutritive substances by the pleurotus ostreatus, and effectively shorten the cultivation period of the pleurotus ostreatus, and increase the protein content of the pleurotus ostreatus . During preparation of the culture medium, porous lotus-shaped apple pomace ultrafine powder is used to adsorb loaded yeast, so that good living space is provided for the yeast, active time of the yeast is prolonged, substrate decomposition is promoted, balanced nutrients are provided for the pleurotus ostreatus, and a foundation for efficient cultivation of the pleurotus ostreatus is provided.

Description

technical field [0001] The invention relates to the field of edible fungus culture medium, in particular to a high-efficiency culture medium capable of effectively increasing the protein content of oyster mushrooms and a preparation method thereof. Background technique [0002] Pleurotus ostreatus is a widely cultivated edible fungus, rich in protein, minerals and amino acids. Among them, Pleurotus ostreatus protein is a kind of polymer substance with obvious biological activity in Pleurotus ostreatus, which can enhance the immune function of the body, and has obvious effects on improving the metabolism of the human body, lowering cholesterol, and preventing and treating hepatitis. The content of protein is an important index to measure the quality of oyster mushrooms, and the medium for cultivating oyster mushrooms is an important factor affecting the content of polysaccharides. Studies have shown that the protein content in Pleurotus ostreatus increases with the increase ...

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
