Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention is a method of mixing sawdust and rice bran with activated carbon or a similar activator, which is used for the cultivation of mushrooms using aerobic bacteria such as Cymene and Ni/°Kidake. This relates to a mushroom culture medium.

(Prior art) The conventional mushroom culture medium is made by adding fresh rice bran to relatively old sawdust, which has a standard water content of about 65%, consisting of appropriately sized particles, and about 173% of the sawdust.
It is said that a mixture of different amounts is most suitable for growing mushrooms.

(Problems to be Solved by the Invention) Generally, mushroom inoculum is cultured by using a bottle and placing the above-mentioned culture medium in it. In addition to creating voids for mycelium to grow sufficiently, it also provides good air permeability, and improves the physical effects such as adsorption of moisture within the particles, which promotes active mycelial reproduction and mushroom growth. However, the moisture content tends to change and become unbalanced due to the surrounding atmosphere and improper handling, and overhumidity can shorten the gaps, resulting in poor air permeability and mycelial growth. Rice bran is a nutritional source for mycelium, but the mushroom sakae contained in the ingredients is 1!
Sources of fat, vitamin B, and nicotinic acid are easily decomposed when temperature and humidity are high (in particular, fat content is easy to hydrolyze and become free acid due to increased humidity, so as mentioned above, changes in the temperature and humidity of sawdust) There were problems such as a great negative effect on the growth of hyphae.

(Means for Solving the Problems) The present invention provides a mushroom culture medium containing an active agent that solves the conventional problems.
If the particles are fine, they tend to become dense when packed in a bottle, reducing the amount of air in the bottle and causing poor growth of mycelium.) Standard water content: 65% (when the outside temperature is high, the standard water content is 65%). Relatively old sawdust that has been adjusted to about 10% less water (or about 5% more when the outside temperature is low) contains rice bran that is about 1/3 of the sawdust and has properties equivalent to 175 to 2151 of the total amount. The mushroom culture medium is formulated with highly hygroscopic and breathable activated carbon or a similar activator.

(Function) As mentioned above, the temperature, moisture content, and air permeability of the culture medium for the inoculum greatly influence the growth of mushrooms.

Due to poor management during manufacturing or bacterial growth, the culture medium may not only contain uneven moisture content, resulting in overhumidity and regression, but also overhumidity inhibits aeration, even though the mycelia are aerobic. However, the activated carbon and other activators uniformly blended into the culture medium absorb water and even out the overall water content, as well as absorb harmful gases and promote healthy bacterial growth. Voids (bubbles) in each Nishimata activator
This improves air permeability, and the water absorbed by the active agent prevents partial oversaturation of the culture medium, promoting the growth of mycelia and the generation of mushrooms.
