Problems solved by technology

[0004] Although the advantages of liquid submerged fermentation culture are great, the current liquid medium is not good for the cultivation of Pleurotus osmanthus mycelium in liquid submerged fermentation, and the cost of liquid medium is relatively high, so it is not suitable for large-scale industrial production
At the same time, the technology of submerged liquid fermentation to cultivate Pleurotus erodes

Example Embodiment

[0061] Example 1

[0062] The present embodiment provides a method for cultivating Pleurotus erodes mycelium by liquid submerged fermentation, which comprises:

[0063] Weigh 1.5kg of peeled potatoes, add appropriate amount of water to boil for 18min, filter with 4 layers of gauze to obtain the filtrate, add 0.15kg of agar powder and 0.15kg of sucrose to the filtrate, add water to a total volume of 10L, mix, melt, and pack , sterilized at 120°C for 18 minutes to obtain the initial slant medium; put the initial slant medium into a constant temperature incubator and cultivate it for 2 days, observe whether there are any miscellaneous bacteria such as mold, if not, it is the slant medium that can be inoculated.

[0064] Inoculate the mother species of Chrysanthemum pleurotus on the slant medium, and the quality of the mother species of Pleurotus osmanthus is 3% of the mass of the slant medium. Place the inoculated slant medium in a constant temperature incubator at 26-30° C. for...

Example Embodiment

[0069] Example 2

[0070] The present embodiment provides a method for cultivating Pleurotus erodes mycelium by liquid submerged fermentation, which comprises:

[0071] Weigh 2.5kg of peeled potatoes, add appropriate amount of water to boil for 22min, filter with 5 layers of gauze to obtain the filtrate, add 0.25kg of agar powder and 0.25kg of sucrose to the filtrate, add water to a total volume of 10L, mix, melt, and pack , sterilized at 122°C for 22 minutes to obtain the initial slant medium; put the initial slant medium into a constant temperature incubator and cultivate it for 3 days, observe whether there are molds and other miscellaneous bacteria, if not, it is the slant medium that can be inoculated.

[0072] Inoculate the mother species of Chrysanthemum pleurotus on the slant medium, and the quality of the mother species of Pleurotus osmanthus is 5% of the mass of the slant medium. Place the inoculated slant medium in a constant temperature incubator at 30°C for 5 day...

Example Embodiment

[0077] Example 3

[0078] The present embodiment provides a method for cultivating Pleurotus erodes mycelium by liquid submerged fermentation, which includes:

[0079] Weigh 3kg of peeled potatoes, add an appropriate amount of water to boil for 20min, filter with 4 layers of gauze to obtain the filtrate, add 0.2kg of agar powder, 0.2kg of sucrose to the filtrate, add water to a total volume of 10L, mix, melt, and pack. Sterilize at 121°C for 20 minutes to obtain the initial slant medium; put the initial slant medium into a constant temperature incubator and incubate for 3 days, observe whether there are any miscellaneous bacteria such as mold, if not, it is the slant medium that can be inoculated.

[0080] Inoculate the mother species of Pleurotus chinensis on the slant culture medium, and the quality of the mother species of Pleurotus chinensis is 4% of the mass of the slant medium. Place the inoculated slant medium in a constant temperature incubator at 28°C for 4 days, and...

Abstract

The invention provides a liquid culture medium used for cultivating pleurotus geesteranus mycelia and relates to the field of strain culture. The liquid culture medium comprises the following components by weight percent: 3-5% of a carbon source, 3.5-6.5% of a nitrogen source, 0.08-0.12% of inorganic salt, 0.0035-0.0065% of vitamin and water; the liquid culture medium adopts an appropriate carbon source, a nitrogen source, inorganic salt and vitamin and ratio, all the raw materials of the liquid culture medium are synergistic, the culture effect on the pleurotus geesteranus mycelia is good, and the cost is low, so that the liquid culture method is applicable to large-scale submerged liquid fermentation culture of the pleurotus geesteranus mycelia. The invention also provides a method for cultivating the pleurotus geesteranus mycelia through submerged liquid fermentation. The method utilizes the liquid culture medium for carrying out activation amplification fermentation culture on pleurotus geesteranus original strains for multiple times and is applicable to the large-scale submerged liquid fermentation culture of the pleurotus geesteranus mycelia.

Description

technical field [0001] The invention relates to the field of strain culture, and in particular to a liquid culture medium and a liquid submerged fermentation culture method for cultivating pear mushrooms. Background technique [0002] As an important biological resource, edible fungi are not only delicious, low in fat and low in energy, but also rich in nutrients such as dietary fiber, vitamins and protein, and are developing into the third type of food after animal food and plant food. , that is, fungal food. In addition, edible fungi can also improve the immune function of the human body, prevent and treat various chronic diseases, and have significant effects in anti-aging and other aspects. Among many edible fungi, xiuzhen mushroom is widely eaten because of its delicious taste, high nutritional value, and simple planting conditions. Xiuzhen mushroom belongs to the fungus door, Agaricaceae, Basidiomycetes, Pleurotaceae, Pleurotus genus, also known as small oyster mushr...
