Selenium-rich mushroom collagen culture medium

Abstract

The invention discloses a selenium-rich mushroom collagen culture medium. The selenium-rich mushroom collagen culture medium is prepared from, by weight, 0.3-0.4 part of selenomethionine, 2-3 parts of selenium-enriched yeast, 30-32 parts of cottonseed meal, 24-26 parts of buckwheat hull, 1.3-1.6 parts of hydroxyethyl ethylenediamine triacetic acid, 1-2 parts of nickel sulfate, 3-5 parts of calcium hydrophosphate, 5-6 parts of talcum powder, 44-48 parts of pigskin waste, 2-3 parts of sodium chloride powder, a proper amount of acetum with the pH being 2.5, a proper amount of a sodium hydroxide solution and a proper amount of water. According to the selenium-rich mushroom collagen culture medium, the selenium-enriched yeast, selenomethionine and other organic selenium sources are added and integrated into the culture medium through a high-temperature chelation process, contamination possibly generated by yeast serving as infectious microbe is avoided, the selenium-rich mushroom collagen culture medium can be efficiently absorbed by mushrooms, the high-toxicity risk of added inorganic selenium is avoided, and the selenium-rich mushroom collagen culture medium has a good promoting function on increasing the nutritive value of the mushrooms and the economic benefits of mushroom culture.

Description

Technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a selenium-enriched mushroom collagen cultivation substrate. Background technique [0002] Shiitake mushroom, commonly known as Chinese mushroom, is a famous edible medicinal material used to cultivate fungi. It has a long history of cultivation in my country. It is loved by consumers for its rich nutritional value and medicinal value. It has now become the second in the world. For large artificially cultivated edible fungi, due to the rapid development of the industry, the raw materials of the traditional substrate for the cultivation of mushrooms are becoming exhausted, and it is necessary to actively explore ways to replace the substrate. On the other hand, with the improvement of people's living standards, people hope that the nutritional value and medicinal value of mushrooms can also be improved, so it is necessary to provide a high-quality mushroom cultivation ...

Problems solved by technology

[0006] The invention patent application with the publication number 102617213A discloses a method of using compressed straw to prepare a mushroom cultivation substrate. The cultivation substrate uses 25-35% coarse wood chips, 15-25% fine wood chips, and It is prepared by mixing soaked compressed straw particles, 10-15% bran, and 1.0-1.5% gypsum. The culture substrate of the invention has a high lignin content, which is conducive to the utilization of shiitake mushroom hyphae, and agricultural production waste is used as cultivation Substrate raw materials improve the environment and save costs, but the cultivation substrate disclosed in the invention uses too single raw materials, which easily causes nutrient imbalance and requires the addition of additional nutrients. At the same time, the biocompatibility with shiitake mushrooms is not high. The improvement of the microenvironment and the expansion of mycelium have no promotion effect, and there is no significant increase in added value, which limits the large-scale application of the invented substrate
