Problems solved by technology

[0005] (1) After the culture tank is fermented, it is easy to produce harmful gas, and then after the gas is discharged, it will cause environmental pollution, thereby reducing the environmental protection during the cultivation process;
[0006] (2) During inoculation and cultivation, the air inside the cultivation device can easily contain bacteria, which will affect the quality of the strains during the fermentation process

Embodiment 1

[0030] like figure 1 Shown, the invention provides a kind of culture method of high-protein Pleurotus eryngii liquid bacterial classification, comprises the following steps:

[0031] Step 1: The proportioning material of the culture medium of the liquid strain: by weight percentage, white sugar 10-30, soybean meal powder 2-5, potato 15-25, peptone 0.6-1.2, potassium dihydrogen phosphate 0.6-1.2, magnesium sulfate 0.02-0.6, vitamin B0.02-0.6, vegetable oil 0.02-0.08, appropriate amount of water, pH value 7.0-8.0;

[0032] Step 2: Mixed material liquid: Coordination figure 2 , take the juice through potato processing, then mix the potassium dihydrogen phosphate and magnesium sulfate according to the corresponding proportion, then add the potato juice, when fully mixed, add some water with white sugar, soybean meal powder, vitamin B, vegetable oil and peptone , mixed in the stirring device, and then added to the mixed juice for mixing and stirring;

[0033] Step 3: Sterilizat...

Embodiment 2

[0037] On the basis of Example 1, the present invention provides a technical solution: preferably, after the potatoes are boiled and processed, the residues of the potatoes are filtered with a filter, so that there will be no particles in the potato juice, thereby not affecting The quality of mixed juice water; put potassium dihydrogen phosphate, magnesium sulfate and water into the inside of the mixing tank, mix and stir, and then place them in the inside of the mixing tank in the order of white sugar, soybean meal powder, vitamin B, vegetable oil and peptone , to achieve full mixing;

[0038] Step 3 also includes: setting a filter device inside the air inlet of the culture tank, using the filter effect of the filter device to filter the particulate matter in the air, improving the quality of the injected air, and effectively improving the quality of the liquid bacteria; cultivating The exhaust port of the tank is equipped with a purification device, and a spraying device is ...

Embodiment 3

[0041] like Figure 4 As shown, on the basis of Example 1, the present invention provides a technical solution: Preferably, step 4 also includes: when inputting air into the culture tank, cooperate with the purification function of the air purification device to make the air inside the tank , to provide a sterile environment, which is conducive to the production of liquid bacteria. Use the temperature detection device inside the culture tank to detect the internal temperature, so that it is convenient for the device to regulate the internal temperature, thereby providing a better culture environment.

[0042] In this embodiment, the air is sterilized at high temperature through the interior of the air purification device, and filtered with the injection port, so as to improve the sterile air for the air inside the culture tank, which is beneficial to the production of liquid bacteria, and then improves the quality of liquid bacteria. the quality of.

Abstract

The invention discloses a culture method of a high-protein pleurotus eryngii liquid strain. The culture method comprises the following steps of preparing materials, processing potatoes, taking juice, mixing potassium dihydrogen phosphate and magnesium sulfate, adding the potato juice, fully mixing, adding white sugar, soybean meal, vitamin B, vegetable oil and peptone, adding water, and mixing in stirring equipment, sterilization treatment: putting the blended mixed juice into a culture tank to prepare a culture solution, and inoculating culture: placing the mother strain in sterile water, when a culture solution is cooled to 30 DEG C, opening a tank for inoculation, then sealing a cover immediately, introducing sterile air for culture, acquiring a liquid strain, and injecting the liquid strain into a pleurotus eryngii cultivation bag after being inspected to be qualified. According to the culture method of the high-protein pleurotus eryngii liquid strain, the influence of bacteria in the fermentation process can be reduced, and the strain quality is improved; the pollution of harmful gas generated by fermentation to the environment can be reduced, and the environmental protection property of the culture process is improved.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a method for cultivating high-protein Pleurotus eryngii liquid strains. Background technique [0002] Liquid strain production technology is a new production method in the production of edible fungi. It is the application of biological fermentation technology in agricultural production. With the development of edible fungus production technology and the improvement of scale, factory and modernization of production, the production technology of liquid bacteria will have more and more extensive application value. [0003] Chinese invention patent 201810690874.2 discloses a liquid strain culture method and cultivation method of black boletus. After the cultivation of six stages of silk recovery, culture adaptation germination, hyphae growth, hyphae multiple growth period, and adaptation period before inoculation, the fermentation is completed; wherein,...
