Embodiment 1

[0013] Edible fungus culture medium includes matrix material and nutrient solution. The matrix material is composed of several spherical particles made of polymeric alginate, and the granules contain nutrient solution.

[0014] The preparation method of edible fungus culture medium is as follows: 1) Prepare nutrient solution; 2) Soak the matrix material in 100 times the nutrient solution to allow it to fully absorb; 3) Drain the excess nutrient solution that has not been absorbed, and then drain the matrix The material is put into a container (bottle or test tube), and the mouth of the bottle (tube) is routinely closed, sterilized in a pot, and cooled.

Embodiment 2

[0016] Edible fungus culture medium includes matrix material and nutrient solution. The matrix material is composed of several block particles made of cross-linked polyacrylic acid salt, and the granule contains nutrient solution.

[0017] The preparation method of edible fungus culture medium is as follows: 1) Prepare nutrient solution; 2) Soak the matrix material in 200 times the nutrient solution to allow it to fully absorb; 3) Drain the excess nutrient solution that has not been absorbed, and then drain the matrix The material is put into a container (bottle or test tube), and the mouth of the bottle (tube) is routinely closed, sterilized in a pot, and cooled.

Embodiment 3

[0019] Edible fungus culture medium, including matrix material and nutrient solution, the matrix material is composed of block particles made of several cross-linked polyacrylates, the granules contain nutrient solution, and fine wood chips or grass clippings are added 10 %.

[0020] The preparation method of edible fungus culture medium is as follows: 1) Prepare nutrient solution; 2) Soak the matrix material in 200 times the nutrient solution to allow it to fully absorb; 3) Drain the excess nutrient solution that has not been absorbed, and then drain the matrix Put the material into a container (bottle or test tube), add 10% fine wood chips and grass clippings at the same time, mix them together, then close the mouth of the bottle (tube) routinely, put it in a pot for sterilization, and cool it down.

Abstract

The invention discloses a novel strain culture medium for edible fungi. The novel strain culture medium comprises a host material and a nutrient solution. The novel strain culture medium is characterized in that the host material is composed of a plurality of grains made of high water absorbent materials; the grains absorb the nutrient solution. Furthermore, a preparation method of the strain culture medium for the edible fungi comprises the following steps: (1) preparing the nutrient solution; (2) soaking the host material into the 50-200-time nutrient solution to sufficiently absorb the nutrient solution; and (3) after leaching the surplus nutrient solution which is not absorbed, filling the host material into a container (a bottle or a test tube), regularly sealing a bottle (tube) opening, and filling the container into a pot to be sterilized and cooled. According to the novel strain culture medium for the edible fungi, the characteristics of high water-absorbing quality and grain sizing of the high water absorbent materials are utilized and a strain production procedure can be simplified; the quality of the strain is improved and raw materials including grains, wheat bran and the like are saved; the novel strain culture medium can be used for preparing various strains including edible fungus mother strains, raw strains, culture strains, special mother strains for liquid fermentation and the like.

Description

technical field [0001] The invention relates to edible fungus strain culture technology, in particular to an edible fungus strain culture medium and a preparation method thereof. Background technique [0002] At present, for the preparation of edible fungus culture medium, the mother species (first-level strain) generally adopts agar slant medium, and the procedures such as boiling agar, test tube filling, and slant placement are complicated; the original species (second-level strain), cultivation Seed (tertiary strain) culture medium generally uses sawdust, straw, wheat bran to prepare culture medium, or grains such as grains, wheat grains, corn grains to prepare medium, and the process of mixing materials, soaking grains, etc. is complicated . Due to the limited water content of the culture medium of ordinary strains, the storage period of the strains is short, and the inoculation after a long storage time will lead to a decrease in germination ability. The invention uti...
