Problems solved by technology

The unique environmental conditions of Tibet endow plateau black fungus with the characteristics of high nutritional value and high price; but also because of the special geographical environment of Tibet, such as high ultraviolet light and different forest matrix environment, the yield of local fungus on the plateau is generally low, which also makes the inland excellent Fungus varieties are "acclimatized" in Tibet, and their quality and taste have declined significantly

specific Embodiment approach 1

[0014] Specific Embodiment 1: In this embodiment, black fungus HDXZ-1 (Auricularia auricular HDXZ-1) was preserved in the China Center for Type Culture Collection, with the preservation date being January 21, 2013, and the preservation number is CCTCC NO: M2013032.

[0015] Black fungus HDXZ-1 (Auricularia auricular HDXZ-1) was collected from Nanyigou Scenic Area, Milin County, Tibet, at an altitude of 2800m.

[0016] Black fungus HDXZ-1 (Auricularia auricular HDXZ-1) was initially identified as black fungus by morphology.

[0017] The collected black fungus HDXZ-1 (Auricularia auricular HDXZ-1) specimens were removed from the dirt, fumigated with potassium permanganate-formaldehyde solution for 30 minutes, and then the fruiting bodies were placed on the ultra-clean bench for aseptic separation ( Pick up the gelatinous part of the fruiting body with an inoculation shovel), inoculate the isolated gelatinous part (soybean grain size) into the center of the PDA medium, cultivate ...

specific Embodiment approach 2

[0046] Specific implementation mode 2: In this implementation mode, a comparative test is carried out on black fungus HDXZ-1 (Auricularia auricular HDXZ-1), excellent inland varieties of fungus, and excellent inland varieties of fungus transplanted to Tibet:

[0047] Sample No. 1 is black fungus in Dongning, Heilongjiang, which is black fungus Yuanbao No. 2 isolated from Bidekin Edible Fungi Research Institute in Dongning County;

[0048] Sample No. 2 is black fungus in Dongning, Heilongjiang, which is black fungus A4 isolated from Bidekin Edible Fungi Research Institute in Dongning County;

[0049] Sample No. 3 is Yuanbao black fungus No. 2 transplanted to Tibet;

[0050] Sample No. 4 is black fungus A4 transplanted to Tibet;

[0051] Sample No. 5 is black fungus HDXZ-1 (Auricularia auricular HDXZ-1).

[0052] 1. The hardness comparison test results are as follows: figure 2 As shown, it shows that the hardness of the inland fungus transplanted to Tibet is significantly in...

Abstract

The invention discloses a black fungus strain on a plateau and relates to a black fungus strain. The black fungus strain on the plateau is black fungus HDXZ-1 (Auricularia auricular HDXZ-1) and preserved in a typical culture preservation center of China, and the serial number for preservation is CCTCC NO: M2013032. The black fungus strain on the plateau is applied to the field of black fungus cultivation.

Description

technical field [0001] The invention relates to a black fungus strain. Background technique [0002] Black fungus is a saprotrophic edible fungus. In the two stages of growth and development, mycelium penetrates into the substrate, and the organic matter in the degraded substrate absorbs the released nutrients to provide its own nutrition and reproductive needs. Black fungus is a traditional edible fungus in my country. It is known as "vegetable meat and meat among vegetarians". It is known as a human body scavenger and is a healthy food in people's lives. [0003] Tibetan black fungus is the best among mountain delicacies on the Qinghai-Tibet Plateau. It is a saprophytic fungus that grows on rotten wood and consists of mycelium and fruiting bodies. The unique environmental conditions of Tibet endow plateau black fungus with the characteristics of high nutritional value and high price; but also because of the special geographical environment of Tibet, such as high ultraviol...
