Description

Technical Field

[0001] The invention relates to the technical field of culturing and growing Sanguinea spp., and in particular to a method for cultivating Sanguinea spp. strains and bottling the strains. Background Art

[0002] In recent years, due to the value of edible fungi, people have gradually increased the collection of wild edible fungi, resulting in a significant reduction in edible fungi germplasm resources. In order to protect my country's edible fungi germplasm resources and species diversity, it is very necessary to carry out research on the isolation and identification of wild edible fungi.

[0003] Tremella sanguinea, also known as blood tremella, red ear, and blood wood ear, is a rare edible fungus in the genus Tremella. It possesses extremely high nutritional and medicinal value. However, due to its limited distribution and environmental conditions, wild resources of Tremella sanguinea are extremely scarce, and research on the subject is limited. Tremella sanguinea exhibits the parabiotic characteristics common to Tremella genus fungi, requiring the presence of these parabiotic fungi for growth. Current isolation techniques for Tremella sanguinea are immature, and only the yeast-like basidiospores and hyphae of the parabiotic fungi can be isolated. Consequently, using these as inoculum yields are inconsistent. Patent No. CN 105154335 B discloses a method for cultivating a mixed strain of blood ear fungus, specifically: separating the ear fungus and blood ear basidiospore species from wild blood ear fungus, purifying and preliminarily culturing them separately to obtain two strains; respectively, expanding the two strains in a liquid culture medium, mixing the two strains after the expansion culture is completed to obtain a mixed liquid strain; mixing the mixed liquid strain and inoculating it into a solid sawdust bran culture medium, cultivating to obtain a blood ear solid mixed strain for blood ear cultivation, and cultivating the mixed strain to maturity for log cultivation to obtain a blood ear finished product. The method has the disadvantages that the blood ear basidiospores do not germinate into mycelium, resulting in no ears or few ears, and there is also the disadvantage that blood ear can only be cultivated on logs, and substitute material cultivation has not yet been achieved. The present invention studies the separation of wild blood ear fungus species and substitute material cultivation in order to protect the blood ear germplasm resources and lay a certain foundation for subsequent development and application.

The flask was covered with a breathable sealing film and cultured at 25 ° C. The fruiting bodies were taken out after one day. The spores began to germinate in about two days and appeared as white yeast. Single basidiospores were picked and purified in PDA modified + peanut solid culture medium (200 g / L potato, 20 g / L glucose, 5 g / L peptone, 3 g / L KH2PO4, 1.5 g / L MgSO4, 10 g / L peanut, 20 g / L agar, 1 L distilled water). The blood ear basidiospores ( Figure 1 Collect wood from the base of the blood ear, disinfect the surface with 75% alcohol, cut the wood into small pieces the size of rice grains in a clean bench, soak them in 75% alcohol for 30 seconds, then wash them three times with sterile water, and then dry the surface moisture with sterilized gauze or filter paper, and culture them on PDA modified + peanut solid medium (potato 200 g / L, glucose 20 g / L, peptone 5 g / L, KH2PO4 3 g / L, MgSO4 1.5 g / L, peanut 10 g / L, agar 20 g / L, distilled water 1L) at 25℃. Mycelia germinated after 3 days, and the terminal mycelia were picked and cultured on PDA modified + peanut solid medium (potato 200 g / L, glucose 20 g / L, peptone 5 g / L, KH2PO4 3 g / L, MgSO4 1.5 g / L, peanut 10 g / L, agar 20 g / L, distilled water 1L). g / L, distilled water 1L) for purification and culture, and the mycelium of the associated fungus was obtained ( Figure 2 ).

[0033] (2) Spore pairing: Pair the collected single Sanguinea basidiospores in pairs. Pick different Sanguinea basidiospores and use the spore pairing method to place different single yeast-like basidiospores in pairs on PDA modified + peanut solid culture medium (potato 200 g / L, glucose 20 g / L, peptone 5 g / L, KH2PO4 3 g / L, MgSO4 1.5 g / L, peanut 10 g / L, agar 20 g / L, distilled water 1L), about 0.5 cm apart, and culture at 25℃. When the two basidiospores grow to contact, hyphae will germinate at the edge of their contact ( Figure 3 ), observe the germination of mycelium, record the pairing combination of germinated mycelium, and then pick the germinated mycelium for pure culture to obtain pure mycelium of Haemophilus influenzae ( Figure 4 ), be careful not to touch the yeast-like spores when picking.

[0034] (3) Mother culture: The above-mentioned mycelia of the associated fungi and the pure mycelia of Sanguinea odorata were inoculated on PDA modified + peanut solid culture medium (potato 200 g / L, glucose 20 g / L, peptone 5 g / L, KH2PO4 3 g / L, MgSO4 1.5 g / L, peanut 10 g / L, agar 20 g / L, distilled water 1 L), and then placed at 25°C for dark culture for 10 days to obtain the cultivated mother culture.

[0035] (4) Preparation of cultivation bottles: Soak sawdust, wheat bran, corn flour, and gypsum in water in advance. After soaking thoroughly, place the materials in a cool place to drain the water for later use. Weigh each material according to the ratio in the formula (80 parts sawdust, 14 parts wheat bran, 5 parts corn flour, 1 part gypsum). After weighing, pile the materials together and stir them evenly. Add water to adjust the moisture content of the cultivation material to 60%. The moisture content is measured by grabbing the cultivation material with your hands and holding it tightly. After opening it, the cultivation material clumps together and falls to the ground and scatters. There are water stains on your hands but no clear water drips. Then the prepared cultivation material is divided into 1000ml glass bottles with a size of 9.2cm×18.9cm, with a bottling volume of 0.3-0.4kg per bottle (about half a bottle). The cultivation material is pressed tightly by hand, and an inoculation hole is made in the center. The lid with a breathable membrane is covered, and the surface stains of the filled bacteria bottle are wiped clean and placed in a high-pressure sterilizer for sterilization at 121°C for 3 hours. After sterilization, the bacteria bottle is taken out and placed in the inoculation room. After the bacteria bottle cools to room temperature, it is placed in a clean workbench and inoculated with bacteria. Each bottle is inoculated with the same proportion of blood ear mycelium and associated bacteria mycelium blocks (the mass ratio of blood ear mycelium cultivation mother strain and associated bacteria mycelium cultivation mother strain is 1:1; wherein, the blood ear mycelium / associated bacteria mycelium cultivation mother strain includes blood ear mycelium / associated bacteria mycelium and the remaining solid culture medium). After inoculation, the bacteria bottle is placed at 25°C and cultured in the dark until the mycelium fills the bottle ( Figure 5 ).

[0036] (5) Ear management: After the mycelium fills the cultivation bag, red water droplets appear on the surface ( Figure 6 ), lower the temperature to 20℃, increase the humidity to 85%-95%, ventilate twice a day, and cultivate for about 30 days until the blood ear fruiting body is formed ( Figure 7 ), harvest.

The preparation method of the blood-stain leather fungus extract is as follows: a sterile inoculation hook is used to pick up a blood-stain leather fungus inoculum block from a test tube and place it in the center of a PDA enriched solid culture medium (200 g peeled potatoes, 20 g glucose, 20 g agar, 5 g yeast powder, 2 g peptone, and 1 L water), activate it at 24°C for 7 days, use a 6mm punch to punch a hole in the PDA enriched solid culture medium where the blood-stain leather fungus has grown, then use a sterile inoculation hook to pick up a block and place it in the center of a sawdust culture medium (80 parts sawdust, 14 parts wheat bran, 5 parts corn flour, 1 part gypsum, and a water content of 60%), culture it at 24°C for 30 days, adjust the water content of the culture medium to 60%, accurately weigh 300 g of the sawdust culture medium containing the blood-stain leather fungus, add 1500 mL of water, and boil it in a boiling water bath for 30 minutes, filter it twice through 4 layers of gauze, and add water to make the volume 1 L.

[0042] (3) Randomly pick the hyphae of the single spore germinated from the blood ear for pairwise hybridization, inoculate them 0.5 cm apart on the same plate, and culture them at 25℃. It was found that the blood ear basidiospores could not germinate single spore hyphae on the culture medium containing the extract of their respective associated bacteria like the golden ear or the white ear. Figure 8 ). Instead, it is necessary to pair the collected single Sanguinea basidiospores in pairs as in Example 1 of the present application. Different Sanguinea basidiospores are picked and, using the spore pairing method, different single yeast-like basidiospores are placed in pairs on a PDA+peanut plate culture medium, about 0.5 cm apart, and cultured at 25°C. When the two basidiospores grow to contact each other, hyphae will germinate at the edge of the contact to obtain pure Sanguinea mycelium.
