RU38528U1 - CAPACITY FOR GROWING THE MYCELIUM OF HIGHER MUSHROOMS AND THEIR FRUIT BODIES - Google Patents

Abstract

The utility model relates to devices used in biotechnology, namely when growing mushrooms and their seed mycelium. The capacity is manufactured in stages as follows:

- make a hole in the container, for example a plastic or polypropylene bag.

- A finely porous filter made of materials capable of preventing the penetration of microbes antagonists of the cultivated fungus, but providing free gas exchange with the internal cavity of the container, is placed on top or under the hole formed. The size of the filter used must exceed the size of the previously made hole.

- The filter is glued to the material of the flexible container using a thermostable self-adhesive tape with a single-sided adhesive coating, in which the previously made hole is aligned coaxially with the hole in the flexible container. The technical result of the proposed device is to reduce the time of manufacture of the container, as well as to prevent the penetration of microbes-antagonists through microcracks in the filter structure that occur during its welding to a flexible container. The effect of using a container for growing mycelium of higher fungi and their fruiting bodies is expressed in the possibility of providing aseptic conditions for a long time for the formed internal cavity of a flexible container after closing its open side in the presence of free gas exchange with the environment only through a fine-porous filter in its design.

Description

The utility model relates to devices used in biotechnology, namely when growing mushrooms and their seed mycelium.

It is known that for the cultivation of fruiting bodies of fungi and their mycelium, sufficient aeration of the substrate is required, since its acidification is possible, especially in cases of waterlogging and long-term storage. Sometimes this leads to a complete stop of the growth of the mycelium of the cultivated fungus and its fruiting bodies. Usually, in order to prevent this, various types of perforations (punctures, incisions, incisions, etc.) are performed on containers for obtaining fruiting bodies of mushrooms, which provide free gas exchange of the growing mycelium with the environment. However, mechanical damage to the container leads to a violation of the aseptic state of the internal cavity of the container and the subsequent active growth of competing microorganisms.

A known method of preparing grain mycelium of higher mushrooms according to patent RU No. 2192119 (Kuznetsov O.Yu., Method of growing mycelium of higher mushrooms, 2002), where the grain is placed in a heat-resistant flexible open container with a geometrically unchanged system, which acts as a filter that prevents extraneous contamination of a sterile grains of competing microorganisms for the cultivated fungus. The sealing component of a geometrically unchanging system,

separating the internal volume of the container from the environment and allowing to maintain the sterility of the grain located in the container, as well as providing free gas exchange between the internal volume and the environment, is usually made of cotton-gauze materials. The fastening of this material is carried out by a ring of heat-resistant material, which is part of a geometrically unchanged system.

The prototype of the proposed device is the manufacture of thermostable containers (bags, bags) with a welded fine-porous filter, which inhibits the penetration of antagonist microorganisms, but provides sufficient gas exchange between the external environment and the internal volume of the container (Stamets P. Growing gourmet medical mushrooms. // Hong Kong: ten Speed Press, 1993. p. 131, p. 138).

The disadvantages of the preparation of flexible containers for subsequent use in the cultivation of cereal mycelium of edible mushrooms and forcing fruit bodies of mushrooms in this case are the following limitations:

1. the filter material must be thermostable and able to weld to the container material;

2. the need to comply with the exact welding mode (pressure, temperature) of the fine-porous filter in order to avoid damage to the filter material and the container at the moment, which can lead to a violation of the tank tightness and the development of competing microorganisms.

The figure shows the proposed capacity for growing mycelium of higher fungi and their fruiting bodies, where 1 is a flexible capacity; 2 - hole in the adhesive tape; 3 - finely porous filter; 4 - hole in a flexible container; 5 - adhesive tape with a single-sided adhesive coating.

The proposed device is manufactured as follows: make a hole in the container, such as a plastic or polypropylene bag. A fine-porous filter made of materials capable of preventing the penetration of microbes antagonists of the cultivated fungus, but providing free gas exchange with the internal cavity of the container, is placed on top or under the hole formed. The size of the filter used must exceed the size of the previously made hole. The filter is glued to the material of the flexible container using a thermostable self-adhesive tape with a single-sided adhesive coating, in which the previously made hole is aligned coaxially with the hole in the flexible container (see photo 1-3).

The technical result of the proposed device is to reduce the time of manufacture of the container, as well as to prevent the penetration of microbes-antagonists through microcracks in the filter structure that occur during its welding to a flexible container.

The effect of using a container for growing mycelium of higher fungi and their fruiting bodies is expressed in the possibility of providing aseptic conditions for a long time for the formed internal cavity of a flexible container after closing its open side in the presence of free gas exchange with the environment only through a fine-porous filter in its design.

Claims (1)

A container for growing the mycelium of higher fungi and their fruiting bodies, flexible and open on one side, having a fine-porous filter, characterized in that at least one hole is made in the container, on top of which or under it a small-porous larger diameter filter is fixed with a self-adhesive adhesive tape with a one-sided adhesive coating, in which the hole made is aligned coaxially with the hole in the flexible container.
