Lucid ganoderma bag cultivation culture medium capable of increasing content of ganoderan and selenium

Abstract

The invention discloses a lucid ganoderma bag cultivation culture medium capable of increasing the content of ganoderan and selenium. The lucid ganoderma bag cultivation culture medium comprises, by weight, 75 parts of wood flour, 20 parts of wheat bran, 2 parts of corn flour, 1 part of lime, 1 part of gypsum and 1 part of sugar. A selenium-enriched nutrient solution is used for adjusting the ratio of the materials to water to be 1: (1.3-1.5). The selenium-enriched nutrient solution is obtained according to a preparation method including: (1), preparing 100 parts of purified water, 1.0 part of L-selenium methionine and 5 parts of corn flour; (2), mixing the raw materials in the step (1), putting the mixture into a high-pressure tank, increasing the pressure to 4kg/cm2 to even the pressure, keeping the pressure for 2-3 minutes, recovering the normal pressure within 1-3 seconds to obtain size, inoculating the size with mature liquid bacillus subtilis cultures by volume percent of 10% at the temperature of 25 DEG C, putting the size into a fermentation tank, injecting sterile air into the fermentation tank, stirring the fermentation tank at the speed of 250r/min, performing fermentation at the temperature of 35-37 DEG C for 4 hours, increasing the temperature to 70 DEG C quickly after fermentation, and keeping 1.0 hour of inactivation to obtain the lucid ganoderma bag cultivation culture medium.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a ganoderma lucidum bag culture medium capable of increasing the content of ganoderma lucidum polysaccharide and selenium. Background technique [0002] Ganoderma lucidum (scientific name: Ganoderma Lucidum Karst), also known as Ganoderma lucidum grass, fairy grass, also known as red lucidum, red lucidum, wood ganoderma, fungus ganoderma, perennial mushroom, ganoderma grass, is the whole plant of polyporaceae red lucidum or purple lucidum. The fruiting body of the fungus Ganoderma lucidum. The shape is umbrella-shaped, and the cap is kidney-shaped, semicircular or nearly circular. Ganoderma lucidum is a precious traditional Chinese medicinal material with a history of thousands of years of medicinal use. It has the effects of invigorating qi and calming the nerves, relieving cough and relieving asthma. Ganoderma lucidum has high medicinal value. After decades ...

AI Technical Summary

Problems solved by technology

[0005] However, the number of naturally grown Ganoderma lucidum is small, and contains a large amount of crude fiber and other impurities, and the polysaccharide content of Ganoderma lucidum is not high (usually 2-5%), so it is not convenient to be directly used as health food or
