Abstract

The invention discloses a phellinus igniarius mycelium liquid fermentation method by utilizing a fungal elicitor for improving the yield of flavone of phellinus igniarius, which comprises the steps of: inoculating a fungal elicitor strain for activated culture, and then inoculating and culturing a fungal block to obtain a fungal elicitor mycelium through filtration; then drying, grinding and crushing the fungal elicitor mycelium, adding the crushed fungal elicitor mycelium into ethanol for soaking, filtering the obtained solution, collecting filter residue, orderly adding a mixed solution of chloroform and normal butanol, acetone and water into the filter residue for washing, adding trifluoroacetic acid into a dry substance after the air-drying, performing boiling water bath for 0.5 to 2 hours, then filtering the obtained solution, taking a filtrate for neutralization, standing the filtrate, using a microporous filtering film with the pore diameter between 0.4 and 5mu m to filter the filtrate for sterilization to obtain the fungal elicitor, and cryopreserving the fungal elicitor at the temperature of between 10 and 20 DEG C below zero; inoculating a phellinus igniarius strain for activated culture, and then inoculating a fungal block for fermentation culture; and adding the fungal elicitor into the phellinus igniarius to continue culturing to obtain a phellinus igniarius mycelium within 1 to 5 days of liquid fermentation culture of the phellinus igniarius. The method has simple process, low cost and remarkable effect, can greatly improve the content of the flavone of phellinus igniarius cells, and is a production method with industrialization prospect.

Description

Technical areas: [0001] The invention belongs to the technical field of bioengineering, and specifically relates to a liquid fermentation method that utilizes fungal elicitors to increase the yield of linteus flavonoids. Background technique: [0002] Phellinus igniarius is a fungus belonging to the subdivision Basidiomycotina, the class Hymenomycetes, the order Polyporales, the family Hymenochaetacae, and the genus Phellinus. A rare large medicinal fungus. Traditional Chinese medicine believes that Phellinus linteus is sweet in nature and bitter in taste, and is used to treat bleeding, anal prolapse, vaginal discharge, amenorrhea, spleen deficiency and diarrhea. Modern pharmacological research shows that Phellinus linteus has anti-tumor, immune-enhancing, and anti-hepatic fibrosis effects. The main active ingredients of Phellinus linteus are polysaccharides, triterpenoids and flavonoids. Among them, flavonoids have antioxidant, blood vessel dilation, blood lipid lowering...
