Problems solved by technology

All there is adopting organic selenium as selenium source in above several technical schemes, the problem of relatively high cost, and the realization of technical method is comparatively difficult, and the selenium content of the glossy ganoderma obtained finally is also lower
[0009] In summary, there are still technical obstacles in the large-scale cultivation of selenium-enriched Ganoderma lucidum. In order to improve the efficiency of selenium accumulation, absorption and utilization of Ganoderma lucidum, the selenium content in Ganoderma can be enriched and accumulated to a more reasonable, safe and efficient level. Effective level, it is very urgent to reduce the usage of selenium agent, reduce production cost, simplify production steps, develop and apply new technology

Abstract

The invention relates to a culture method of ganoderma lucidum rich in selenium, in particular to a culture method of ganoderma lucidum spore powder or sporocarp rich in selenium. The method comprises the steps of preparing a selenium source, preparing a base stock rich in selenium and preparing a culture medium rich in selenium, wherein the selenium source is an inorganic selenium source. According to the method, by converting inorganic selenium absorbed by the ganoderma lucidum in the growth process into organic selenium which is safe, efficient and easy to absorb, increase of active ingredients of the ganoderma lucidum is facilitated, and the cultured ganoderma lucidum is stronger in medicine effect. The culture method of the ganoderma lucidum spore powder or sporocarp rich in selenium is low in cost and has a little poisonous effect on mutiple mycelia, a culture process is simple and easy to implement, and the cultured ganoderma lucidum sporocarp or spore powder is high in selenium content.

Description

technical field [0001] The invention belongs to the field of cultivation technology, and in particular relates to a method for cultivating selenium-enriched ganoderma lucidum spore powder or fruiting bodies. Background technique [0002] Selenium is an essential trace element for the human body and has extremely important biological functions for health. Unlike other semimetals, as part of selenocysteine ​​(the 21st amino acid in protein synthesis in humans), selenium can become part of proteins through a co-translational mechanism. Twenty-five selenoproteins have been identified in humans so far, yet only a few of their functions are understood. Most selenoproteins are involved in the regulation of antioxidant responses and redox states, especially the glutathione peroxidase (GPxs) family and the thioredoxin reductase (TrxRs) family. Some selenoproteins also play more specific and essential roles, for example, thyronine deiodinases (DIOs) are involved in the metabolism of...
