Problems solved by technology

At present, the wild resources of Phellinus japonica have been exploited extinctly, and the price is expensive, and the supply exceeds the demand
Due to the influence of many factors such as climate and environment, the success rate of artificial cultivation of Phellinus japonica for a long period is low
[0005] Phellinus mycelium can be produced by liquid fermentation method, but this method requires a huge investment to produce Phellinus mycelium, and it is difficult to realize it in a short time
[0006] The medicinal effects of wild Phellinus fungus vary significantly due to differences in species, hosts, and origins

Embodiment Construction

[0040] (1) Preparation of solid medium

[0041] Table 1 Unit: Gram

[0042]

[0043] Weigh each component according to the formula in Table 1 and mix evenly, adjust the pH to 6-8 with NaOH and HCl or organic acid or alkali, and sterilize for later use.

[0044] (2), Phellinus strain 4.6302 solid-state fermentation culture

[0045] 1. Cultivation of Phellinus 4.6302 strain test tube strain slant parent species

[0046] Medium: PDA comprehensive medium

[0047] Culture conditions: 6-9 days under dark light at 23-29°C, with natural pH.

[0048] 2. Shake flask seed culture

[0049] Use an inoculation loop to pick out 2 to 3 pieces of bacteria that have been activated in step (1) and inoculate them into a 500ml triangular flask liquid seed medium with a size of 1cm × 1cm. Plug it and wrap the outer layer with kraft paper.

[0050] Medium components (weight): 20-30g sucrose, 3-4g yeast extract, 3-4g peptone, MgSO 4 ·7H 2 O 0.5g, KH 2 PO 4 0.1g, water 1000ml.

Abstract

the invention discloses a morin 4.6302 strain fungal polysaccharide, which is cultivated by 60-80% rice bran, 8-12% corn powder, 8-12% soy powder, 0.8-2.2% glucose, 0.8-2.2% beef grease, 0.04-0.06% MnSO4 and 80-120% water at 22-30 deg.c for 10-20 days.

Description

1. Technical field [0001] The invention relates to a microbial active ingredient and a preparation method thereof, in particular to a medicinal fungal active ingredient and a preparation method thereof, specifically a Phellinus 4.6302 strain mycoplasma polysaccharide and a preparation method thereof. 2. Background technology [0002] Phellinus igniarius belongs to Basidiomycota, Phellimycetes, Phellinaceae, Polyporaceae medicinal fungi. It is named because it usually grows on Morus (Morus.L.) plants, and the fruiting body is yellowish brown. Phellinus has extremely high medicinal value, and has significant effects in enhancing human immunity, anti-hepatic fibrosis, anti-lipid peroxidation, anti-inflammation, etc., especially in anti-tumor. The most effective fungus for cancer. [0003] Phellinus polysaccharides can be applied to the biological effects of anti-tumor, anti-mutation, anti-oxidation, anti-hepatic fibrosis, anti-aging and inhibiting the growth of cells such as ...
