Embodiment Construction

[0005] Take 90Kg of water and 9Kg of potatoes and boil them until crispy, add 1.08Kg of brown sugar, 1.08Kg of glucose, 3.6Kg of wheat bran, 0.18Kg of peptone, 0.18Kg of potassium dihydrogen phosphate, 0.09Kg of magnesium sulfate, 0.9g of vitamin VB1, and 27 ml of Foaming agent, filtered to become Ganoderma lucidum mycelium culture solution, after disinfection, after adding 6 grams of sodium selenite, pour the special species of Ganoderma lucidum liquid into the culture solution, carry out aerobic cultivation, and control the temperature to 25 degrees Celsius, which lasted 72 hours , filter the culture solution to obtain selenium-rich Ganoderma lucidum mycelium.

Abstract

The invention relates to a method for producing ganoderma lucidum mycelia rich in selenium, which comprises the following steps of: inoculating a test tube ganoderma lucidum strain or a special strain for ganoderma lucidum liquid, which is subjected to inoculation and expanding propagation, in culture solution with reasonable carbon nitrogen ratio in a fermentation tank to carry out aerobic fermentation; dissolving a right amount of sodium selenite or sodium selenate in the culture solution in the fermentation tank; controlling a temperature in the range of 22 to 32 DEG C; after 48 to 120 hours, filtering the culture solution in the fermentation tank to obtain the ganoderma lucidum mycelia rich in selenium; and drying and grinding the ganoderma lucidum mycelia rich in selenium to obtain ganoderma lucidum mycelia dry powder.

Description

technical field [0001] The invention relates to a method for producing edible fungus mycelium. In particular, it relates to a method for producing selenium-rich Ganoderma lucidum mycelium, which belongs to the field of microorganisms. Background technique [0002] Selenium is an essential trace element for the human body. Selenium deficiency can cause a variety of diseases in the human body. In most areas of our country, selenium is deficient. Quantitative selenium supplementation is urgent. Because the daily safe intake of inorganic selenium by the human body is narrow, and the human body has a greater tolerance to organic selenium, converting inorganic selenium into organic selenium before being absorbed by the human body is the best way to safely supplement selenium for the human body. Ganoderma lucidum has a strong ability to convert inorganic selenium into organic selenium during the growth process, especially in the growth stage of mycelium, the mycelium has a strong ...
