Pleurotus tuber-regium culture medium rich in selenium and germanium and preparing method thereof

Abstract

The invention discloses a pleurotus tuber-regium culture medium rich in selenium and germanium. The pleurotus tuber-regium culture medium rich in the selenium and the germanium is characterized by comprising, by weight, 20-30 parts of malt, 0.2-0.5 part of sodium selenite, 1-2 parts of yeast, 0.3-0.6 part of germanite powder, 1-2 parts of tourmaline, 10-20 parts of sawdust, 20-30 parts of bran, 6-8 parts of ginseng leaf powder, 10-20 parts of soybean powder, 1-2 parts of chitin xylose, 2-4 parts of chitosan fibers, 1-2 part of negative ion powder, 0.2-0.5 part of malic acid and an adequate amount of water. According to the pleurotus tuber-regium culture medium rich in the selenium and the germanium, inorganic selenium and inorganic germanium are changed into organic selenium and organic germanium respectively by adopting the chitosan fibers for pleurotus tuber-regium to absorb, and humans are benefited; after the yeast is processed through the chitin xylose and bryozoatum, the yeast is cooperated with the pleurotus tuber-regium to paly a part in the growth process of pleurotus tuber-regium hyphae and sporocarp, and the growth of the pleurotus tuber-regium is facilitated. The negative ion powder and the chitosan fibers with positive charges are adopted in the culture medium, surface enrichment of nutrition supplies is facilitated, and absorption and utilization of the pleurotus tuber-regium are convenient.

Description

technical field [0001] The invention belongs to the field of edible fungus cultivation, and in particular relates to a selenium-germanium-rich tiger milk mushroom culture medium and a preparation method. Background technique [0002] Selenium is honored as "the fire of life" by the medical and nutritional circles at home and abroad, and enjoys the reputation of "longevity element", "king of anti-cancer", "patron saint of the heart" and "natural antidote". The content of selenium in human tissue is 1 / 10000000, but it determines the existence of life, and its great effect on human health is irreplaceable by other substances. Selenium deficiency will directly lead to the decline of human immunity. Whether it is animal experiments or clinical practice, it has been shown that sufficient selenium should be obtained from the diet. If it cannot be supplemented in time, the ability to cure diseases will be reduced. Organic germanium has the functions of anti-tumor and immune revival...
