High-effective pleurotus nebrodensis culture medium with algas and preparation method thereof

Abstract

The invention discloses a high-effective pleurotus nebrodensis culture medium with algas, which includes the following components, by weight, sugarcane residue, brewer's grain, alginic acid-polyacrylamide composite porous micro-spherical loofah sponge fibers, chlorella powder, sargassum, hydrilla verticillata powder, kelp powder, cyanobacteria powder, algae residue, grateloupia filicina, cellullase, algal polysaccharides, yeast and lactic acid bacteria. The pleurotus nebrodensis culture medium is prepared from the algas, which are rich in nutrients and bio-active substances, as a main material, so that cultivation period of the culture medium is reduced effectively. During the preparation process of the culture medium, the yeast and the lactic acid bacteria are employed to carry out mix-fermentation, thereby enriching fermentation products. The porous substance is used for supporting the fermentation bacteria so that transmission of heat and nutrients are improved and activity time of the fermentation bacteria is increased. The culture medium is increased in decomposition degree of substrates, is improved in abundance and balance of the nutrients and provides fundament to short-period high-effective cultivation of the pleurotus nebrodensis.

Description

technical field [0001] The invention relates to the field of edible fungus culture medium, in particular to a high-efficiency medium for algae Bailing mushroom and a preparation method thereof. Background technique [0002] Bailing mushroom is rich in nutrition, tender in texture, rich in fragrance, delicious in taste, and has high edible value. At present, there are few cultivars for growth, single main species and long production cycle, which have become important factors restricting the development of Bailing mushroom industry. As a marine by-product, algae are rich in nutrients and biologically active substances, which are of great benefit to the cultivation of edible fungi. [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...

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
