Embodiment 1

[0036] A kind of fungus culture medium formula, described fungus culture medium formula adopts the raw material of following percentage by weight to make:

[0037] Main material: 55%-65%;

[0038] Accessories: 25%-35%;

[0039] The main material includes sawdust, wheat bran and bean cake; the auxiliary material includes glucose, agar, nutrient solution and water.

[0040] Preparation:

[0041] Select any two or all combinations of sawdust, wheat bran and bean cake in the main material according to the preset total weight and the ratio of main material and auxiliary material in the medium, according to the main material: 55%-65% and auxiliary material: 25%- The weight ratio of 35% is weighed and mixed, and then the glucose, agar, nutrient solution and water in the auxiliary materials are added. Stir the mixture evenly, put it into a petri dish, irradiate and sterilize the petri dish with cobalt 60-γ rays, place the sterilized petri dish in a culture shed, and the culture med...

Embodiment 2

[0043] The main ingredients include sawdust: 15-20%, wheat bran: 28%-30%, bean cake: 5%-22%.

[0044] Preparation:

[0045] Select wood chips, wheat bran, and bean cakes in the main ingredients and use weight percentages: wood chips: 15-20%, wheat bran: 28%-30%, bean cakes: 5%-22% by weight, weigh and mix, and then add Glucose, agar, nutrient solution and water in excipients. Stir the mixture evenly, put it into a petri dish, irradiate and sterilize the petri dish with cobalt 60-γ rays, place the sterilized petri dish in a culture shed, and the culture medium is completed. The main material in the medium provides the necessary raw materials for the growth of the fungus, and the nutrient solution in the auxiliary material provides the trace elements and minerals needed in the growth process of the fungus, and is rich in selenium, which promotes the growth of the fungus, and the grown fungus It is rich in selenium and has high nutritional value. In addition, cobalt 60-γ ray i...

Embodiment 3

[0047]The auxiliary materials include glucose: 4%-7%, agar: 8%-12%, water: 20%-25%, nutrient solution: 1%-3%.

[0048] Preparation:

[0049] Select wood chips, wheat bran, and bean cakes in the main ingredients and use weight percentages: wood chips: 15-20%, wheat bran: 28%-30%, bean cakes: 5%-22% by weight, weigh and mix, and then add Glucose, agar, nutrient solution and water in auxiliary materials, of which glucose: 4%-7%, agar: 8%-12%, water: 20%-25%, nutrient solution: 1%-3%, stir the mixture evenly , put into a petri dish, irradiate and sterilize the petri dish with cobalt 60-γ rays, place the sterilized petri dish in a culture shed, and the production of the culture medium is completed. The nutrient solution is rich in selenium, which promotes the growth of the fungus, and the grown fungus is rich in selenium and has high nutritional value.

Abstract

A black fungus culture medium formula is prepared from, by weight, 55%-65% of a main material and 25%-35% of an auxiliary material. The main material comprises wood dust, bran and soybean cakes, and the auxiliary material comprises glucose, agar, nutrient solution and water. A manufacturing method of the black fungus culture medium formula includes: mixing the wood dust, the bran and the soybean cakes in the main material; adding glucose, agar, nutrient solution and water according to a proportion of the main material to the auxiliary material; uniformly stirring the mixture, and putting intoa petri dish; subjecting the petri dish to cobalt 60-gamma ray irradiation sterilization; putting the sterilized petri dish in a culture room. Due to the nutrient solution added into the culture medium is rich in selenium, black fungi growing in the culture medium are rich in selenium and high in nutritive value. By cobalt 60-gamma ray irradiation sterilization of the culture medium, propagation of other bacteria in the culture medium is inhibited, the utilization rate of nutrients in the culture medium is increased, and mixing of other germs in the black fungi is avoided.

Description

technical field [0001] The invention relates to the technical field of fungus planting, in particular to a fungus culture medium formula and a preparation method. Background technique [0002] Selenium is an essential trace element for the human body. Since selenium is an important component of some antioxidant enzymes (glutathione peroxidase) and selenium-P protein in animals and humans, it plays a role in balancing the redox atmosphere in the body. It has the effect of improving animal immunity. Selenium has been regarded as an essential trace element for the human body. At present, the adult intake recommended by the Chinese Nutrition Society is 50-250 micrograms per day, and the selenium intake in 2 / 3 of China is lower than the minimum recommendation Selenium is honored as "the fire of life" by domestic and foreign medical and nutritional circles, and enjoys the reputation of "longevity element", "king of anti-cancer", "heart patron saint" and "natural antidote". The co...
