Problems solved by technology

Sodium citrate and sodium acetate are added to the medium during use, and the yield of Agaricus bisporus is increased by spraying sodium phosphate and potassium phosphate. The labor intensity of the operator is high, and most of the reagents are wasted during the spraying process, which may easily cause changes in water quality.

Embodiment 1

[0039] Embodiment 1: a kind of Amanita liposa strain ( Pholiota adiposa ) YX1

[0040] The strain is collected from the wild forest of Mount Tai. The original strain is obtained through isolation, purification, and cultivation. After domestication, hybridization, breeding, and identification in the laboratory, a strain with powerful medicinal functions and good taste is obtained. sex and scarcity.

[0041] 1. Isolation and screening of strains:

[0042] Select fresh wild Amanita spp. with neat flower shape, large fruiting body, and use the conventional tissue separation method (rinse the fruiting body with running water, dry the water with filter paper, rinse 3 times with sterile water, tear apart mushroom umbrella, take out the white mushroom meat and cut out small pieces, rinse with sterile water 3 times) to obtain sterile tissue blocks. The tissue block was inoculated on the mother seed medium after high-temperature and high-pressure sterilization at 121°C for 30 minutes...

Embodiment 2

[0055] Embodiment 2: the culture method of Amanita liposa strain YX1

[0056] Step 1, mother species cultivation:

[0057] Inoculate the sterile tissue block on the sterilized mother seed medium and culture it in a biochemical incubator at a temperature of 20-25°C to obtain the bacterial block.

[0058] Mother seed medium formula: 150~250g potato, 15~25g glucose, 10~20g yeast extract, 1~3g magnesium sulfate, 1~3g potassium dihydrogen phosphate, 0.3~0.5mg vitamin C, 15~20g agar, water 1000ml. Adjust the pH to 5.5~6.5 and sterilize.

[0059] This formula can make mycelia grow more slender, and the number of cells per unit volume of mycelium is relatively large, which provides conditions for liquid culture in the future.

[0060] Step 2, original seed cultivation:

[0061] Inoculate the bacterial block obtained in step 1 into the original seed medium, place it in an incubator at a temperature of 20-25°C and cultivate it for 4-5 days, and shake the bacteria at a speed of 140-1...

Embodiment 3

[0073] Embodiment 3: Agaricum multiliposa YX1 fruiting body transformation product

[0074] 3.1 Drying products:

[0075] Collect fresh fruit bodies and place them in a dryer at a temperature of 30-35°C for 2-4 hours, then gradually raise the temperature to 40-60°C for 10-14 hours, and bake at 60-65°C 1~2 hours. Dried products are convenient for storage, transportation and sales. Soak the dried fruiting bodies in warm water at 35-40°C for 3-4 hours before eating. The fat-scaled umbrella fruiting bodies maintain the smooth and tender flesh, strong fragrance, and bright color of fresh mushrooms. It can be described as a school of its own among edible mushroom varieties.

[0076] 3.2 Powdered health care products: After drying, the fruiting bodies are ground into powdered products of 100~300 mesh by a 25,000~30,000r / min grinder. Rich in polysaccharides, amino acids, and sterols, it can be ground into powder to extract polysaccharides and other products. The detection results...

Abstract

The invention discloses pholiota adiposa YX1 as well as a culture method and application thereof and belongs to the technical field of edible mushrooms. The pholiota adiposa YX1 has been preserved in the China General Microbiological Culture Collection Center of China Committee for Culture Collection of Microorganisms on December 1, 2020, and the preservation number of the YX1 is CGMCC NO. 21077. According to the pholiota adiposa YX1 as well as the culture method and application thereof, paecilomyces variotii fermentation broth obtained by separating endophytic fungi is used as one of raw materials of a liquid culture medium, so that not only is the mycelium biomass of the pholiota adiposa YX1 increased, but also the cost of the raw materials is reduced, and a technical support is provided for large-scale production. Meanwhile, fermentation liquor of the endophytic fungi is fully utilized, the growth promoting effect on other plants can be achieved, other reagents are not introduced, and ecological environment protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of edible fungi, in particular to a mushroom strain YX1, a culture method and an application thereof. Background technique [0002] Edible fungi refer to a class of higher fungi with large fruiting bodies that can be eaten by humans. They are called mushrooms, mushrooms, and mushrooms by humans, such as Ganoderma lucidum, Hericium erinaceus, Cordyceps sinensis, shiitake mushrooms, and fungus that people are familiar with. Scientists have found that edible mushrooms are rich in nutrients, containing high protein, low fat, various amino acids, vitamins, trace elements, nucleotides, polysaccharides and other ingredients. The nutrients contained are very complete, and they are widely used in food and health care. [0003] In recent years, with the continuous improvement of people's living standards and self-care awareness, the cognition of the nutritional value of edible fungi has also been continuously improved...
