High-effective dendrobium officinale culture medium employing natural bacteria inhibiting substances and preparation method thereof

Abstract

The invention discloses a high-effective dendrobium officinale culture medium employing natural bacteria inhibiting substances, which includes following components, by weight, polyacrylic acid microspheres, porous polysucrose microspheres, modified high-surface-activity mineral powder, soybean bran, peanut straw, bean curd residue, propolis, garlic residue and yeast. In the culture medium, the garlic residue is used for inhibiting growth of contaminating microorganism in early stage of fermentation. The propolis supported on the degradable polyacrylic acid microspheres is added to the culture medium so that with degradation of the polyacrylic acid microspheres, the anti-bacterial effect of the natural propolis is stronger and stronger, thereby providing guarantee of preventing diseases and pollution in last stage of the dendrobium officinale. The culture medium is prepared from the soybean bran with the perlite and the like through fermentation, so that abundant nutrients and loosen and water-permeable excellent environment are provided to the dendrobium officinale. By means of the porous polysucrose microspheres for adsorbing the supported fermentation bacteria, growth of the yeast is promoted and meanwhile fermentation speed of the yeast is reduced, so that the culture medium is more rich and balanced in nutrients, thereby providing fundament to high-effectively cultivation of the dendrobium officinale.

Description

technical field [0001] The invention relates to the field of edible fungus culture medium, in particular to a high-efficiency culture medium of Dendrobium candidum using natural antibacterial substances and a preparation method thereof. Background technique [0002] Dendrobium candidum is a precious medicinal material, which is listed as the first of the nine Chinese immortal grasses. The capsules of Dendrobium officinale are cracked when mature, and the seed particle size is small, so the natural reproduction rate is low. Dendrobium polysaccharide, the main medicinal ingredient, is an immunomodulator. Since ancient times, the resources of Dendrobium candidum have mainly relied on wild resources. With the wide application of Dendrobium candidum in the field of biopharmaceuticals, excessive harvesting has resulted in the depletion of wild resources of Dendrobium candidum. The supply of raw materials is tight and cannot meet market demand. [0003] Natural antibacterial subs...

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
