Abstract

PURPOSE: To produce a Cortinellus shiitake chip spawn considered in long period storage. CONSTITUTION: A Cortinellus shiitake culture medium 30 comprising the mixture of rice bran 31 with saw dust 32 is press-filled into an air-permeable flanged container 40 permitting the passage of Cortinellus shiitake fungus, and the container is covered and sealed with a synthetic film 43 to produce the storage type raw chip capsule 10 having the Cortinellus shiitake culture medium 30 sealed therein. When needed, the raw chip capsule 10 is discharged from the container, immersed in water, drained, thermally sterilized, cooled, and subsequently subjected to the adhesion of the original fungus 25 of the Cortinellus shiitake to the outer wall of the raw chip capsule 10 in an aseptic chamber 24. The Cortinellus shiitake fungus infiltrated into the Cortinellus shiitake culture medium 30 is cultured and bred to produce a Cortinellus shiitake chip spawn 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing shiitake mushroom seed pieces in consideration of long-term storage.

[0002]

2. Description of the Related Art When producing a wood piece, a wood piece is first sterilized by steam sterilizing a wood piece made by cutting a raw wood into a diameter of 8 to 12 mm and a length of 15 to 20 mm, and then producing a mushroom fungus in a sterile room. This is a method to make seed fungus wood pieces, but this method is troublesome. Also, there is a mixture of sawdust and rice bran mixed with Shiitake progenitor bacteria, but since it is processed in a sterile room with many restrictions, it takes a long time to culture and there is no loss of preservation.

[0003]

[Problems to be Solved by the Invention] The method for producing the inoculum wood pieces is troublesome, and the mixture of sawdust and rice bran with Shiitake progenitors is prone to the proliferation of miscellaneous bacteria and a large loss.

[0004]

A means for solving the problems will be described with reference to the drawings. The method for producing shiitake seed pieces according to the present invention is a mixture of shiitake growing medium 30 which is a mixture of 8 to 12 parts by weight, preferably 10 parts by weight of sawdust to 1 part by weight of rice bran, with a diameter of 8 to 11 mm and a depth of 15 to 15. A synthetic resin film 43 is filled with pressure in a breathable container 40 that allows passage of 20 mm of Shiitake bacterium.
After manufacturing the preservation type original piece capsule 10 in which the lid mushroom is sealed and the shiitake growing medium 30 is enclosed, if necessary, the original piece capsule 10 taken out after long-term storage is soaked for 2 hours and then drained for about 20 minutes. After heating and sterilizing at 120 ° C. for 40 minutes and then cooling, the Shiitake mushroom 25 is attached to the outer wall of the original piece capsule 10 in a sterile room, and the Shiitake mushroom is infiltrated into the Shiitake growing medium 30 through the ventilation hole 41 to culture and propagate. It is a method of manufacturing shiitake mushroom pieces.

[0005]

Example: Rice bran 31: 1 by weight to sawdust 32: 8-
12 parts by weight, preferably 10 parts by weight, of the mixed mixture is pressurized and filled into a container 40 with a collar 42 having a diameter of 8 to 11 mm and a depth of 15 to 20 mm and a breathable through hole 41 through which shiitake fungi can pass. At the same time, a synthetic resin film 43 of polyester, polypropylene or the like, which can withstand heating at 120 ° C. for 40 minutes, is heat-sealed and sealed to the collar 42 to manufacture the preservation type original piece capsule 10 in which the shiitake growing medium 30 is enclosed. If necessary, the original piece capsule 10 taken out after long-term storage is soaked in the water tank 21 for about 2 hours and then drained 22 for about 20 minutes.
Put in a bag or container 23 and heat sterilization chamber 2 at 120 ° C for 40 minutes
After heat sterilization in 8 and cooling, Shiitake bacterium 25 is attached to the outer wall of the original piece capsule 10 in the sterile room 24, and the vent hole 4
The shiitake fungus growing medium 30 is infiltrated through 1 and cultured and propagated for about 1 month to produce the shiitake seed piece 11.

[0006]

[Function] As before, drilling a raw wood with a diameter of 8 to 13 mm,
Drill a hole with a depth of 10 to 30 mm. Next, the shiitake mushroom seed pieces 11 are packed in the holes of the raw wood and planted.

[0007]

EFFECT OF THE INVENTION The conventional means for cutting wood to make wood pieces and inserting Shiitake fungi requires a great deal of time to make wood pieces,
There are drawbacks such as large amount of raw wood loss, wood pieces containing almost no nutrients, and many hours required for shiitake cultivation.

A mixture of sawdust and rice bran mixed with Shiitake progenitor is a wax or styrofoam plate as a lid material, which is laid in a humid place with a lid and grows into Shiitake mushrooms. Wait for However, filling the holes in the log,
The wax or styrofoam has the drawbacks that it is difficult to cover the lid and that there is a high risk that bacteria will mix in and proliferate and interfere with the growth of Shiitake fungi.

With the seed piece according to the present invention, all that is required is to take it out of the bag or container and insert it into the hole opened in the raw wood, and it is possible to easily inoculate the bacteria and shorten the time.
