Abalone mushroom liquid strain culture medium based on rhizoma polygoni cuspidate dreg and abalone mushroom liquid strain preparation method

Abstract

The invention discloses an abalone mushroom liquid strain culture medium based on rhizoma polygoni cuspidate dreg. The culture medium is prepared from, by weight, rhizoma polygoni cuspidate dreg, abalone protein powder, soybean enzymolysis small molecule peptides, maltose, ribose, cinnamyl acetate, cuttlebone, nanoscale tourmaline powder, bacteria nanometer cellulose and the like. With maltose and ribose as the carbon sources and the soybean enzymolysis small molecule peptides and abalone protein powder as the nitrogen sources, through the combination of processed superfine-expansion rhizoma polygoni cuspidate dreg and rhizoma polygoni cuspidate dreg extracts, the abalone mushroom liquid strain culture medium is prepared; the culture medium is rich in nutrient, the medicinal functions of abalone mushroom can be enhanced, and rich raw materials of the abalone mushroom liquid strain culture medium are provided; in addition, due to the addition of bacteria nanometer cellulose and the high pressure homogenization treatment, the stability and uniformity of the liquid strain culture medium and the existence of micro-spaces in the culture medium are ensured, the effect of improving the quality of mycelium pellets can be achieved, and the quality of abalone mushroom liquid strain fruiting bodies is improved.

Description

technical field [0001] The invention relates to the technical field of liquid strains, in particular to an abalone mushroom liquid strain culture medium based on Polygonum cuspidatum slag and a method for preparing abalone mushroom liquid strains. Background technique [0002] In the production process of abalone mushrooms, liquid strains have incomparable advantages over solid strains. Liquid strains have short production cycle, short and consistent bacterial age, high purity, strong vitality, simple and quick inoculation, and easy industrialization and large-scale production. , standardized production and other advantages. Now, more and more people are researching and using liquid strains, and the promotion and use of liquid strains is also an inevitable trend to realize industrialization, scale and standardization of edible fungi. However, liquid strains also have their own defects and deficiencies: 1. The germination point of liquid strains usually grows quickly, but th...

AI Technical Summary

Problems solved by technology

However, liquid strains also have their own defects and deficiencies: 1. The germination point of liquid strains usually grows quickly, but the penetrating power is not strong. If the compost is too thick, mycelium is not easy to penetrate the compost, and the mycelia will follow the compost. The surface grows rapidly, and the amount of mycelium inside the compost is very small, which seriously affects the yield and quality of the strain; 2. Although the conventional liquid strain solves some problems existing in the solid strain, it can significantly shorten the cultivation cycle and enhance the growth rate of the strain. Species vigor and stress resistance, reducing the contamination rate of strains, and improving the uniformity of strain quality, but there are still some deficiencies such as the density, size, and uniformity of the bacterial balls in the liquid strains obtained by fermentation are not very ideal. If the bacteria balls are crushed by stirring and shearing, the uniformity of the obtained strains will be more ideal. However, the shear force of high-speed stirring, crushing and beating will greatly damage the strains and have a serious impact on the overall quality of the strains.

Publication No. CN105309194A "New Technology for the Production of Edible Mushroom Microparticle Liquid Strain" provides a kind of edible fungus microparticle liquid strain with a mycelium ball particle diameter of 0.5mm, which increases the ventilation rate of the edible fungus liquid strain culture solution, so that the ventilation rate It is suitable at 1:0.6—0.9V / V·min. At the same time, a stirrer is installed in the aerated fermenter to make the eddy current of the culture liquid move and prolong the technical operation method of the air bubble. The method for producing the microparticle liquid strain is from the production process There is no improvement in the aspect of liquid culture medium, and the implementation is technically difficult and demanding; Publication No. CN105130516A "Method for Making Molecular-level Biological Medium" mentions that the nutrients of molecular-level biological medium can be absorbed quickly and comprehensively. Promotes the growth of liquid strains, but does not mention the effect of molecular-grade biological media on the diameter of liquid strain mycelium balls
