[0016] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed account of the Hericium erinaceus strain, spores, fruiting bodies, cultivation method, and applications proposed in this invention. The advantages and features of this invention will become clearer from the following description. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise proportions, used only to facilitate and clarify the illustration of the embodiments of this invention. Unless otherwise specified, the experimental methods used in the following embodiments are conventional methods. Unless otherwise specified, the materials and reagents used in the following embodiments are commercially available.

[0017] This invention provides a strain of Hericium erinaceus, Finc-H-1, named Finc-H-1, belonging to Hericium erinaceus, deposited at the China General Microbiological Culture Collection Center, address: No. 3, Courtyard 1, Beichen West Road, Chaoyang District, Beijing, with accession number CGMCC No. 42091 and deposit date of August 29, 2025.

[0018] The novel Hericium erinaceus strain Finc-H-1 of this invention was obtained through multispore self-pollination of the parent strain Hu Hou 28. Multiple strains were obtained by mixing and culturing a large number of basidiospores (haploids with diverse genetic backgrounds) produced by the fruiting bodies cultivated from the parent strain Hu Hou 28. These strains were then cultured, and a new strain with strong resistance to contaminating bacteria, high fruiting body yield stability, and delicious taste was selected and named Finc-H-1.

[0019] The characteristics of the newly bred Hericium erinaceus strain Finc-H-1 are as follows:

[0020] Strain morphological characteristics: The mycelial morphology of the new Hericium erinaceus strain Finc-H-1 after cultivation on PDA medium is as follows: Figure 1 and Figure 2 As shown, the mycelia of strain Finc-H-1 are white and fluffy, with irregular colony edges and pigment production. Aerial hyphae are well-developed and exhibit strong climbing ability. Under suitable conditions, the mycelia grow rapidly, typically covering a 9cm diameter petri dish in 10-12 days.

[0021] Fruiting body cultivation conditions: Through the inventors' research, the fruiting bodies of the new strain Finc-H-1 can grow well within a temperature range of 16-18℃. The strain Finc-H-1 has a wide humidity tolerance range; a cultivation medium moisture content of 60%-70% and a relative humidity of 85%-95% promote normal growth and development of the fruiting bodies. Regarding pH, the Finc-H-1 strain grows best in an environment with a pH of 5.5-7.0, with optimal growth at a pH of 6.0-6.5. Compared with other common Hericium erinaceus strains, the Finc-H-1 strain exhibits outstanding resistance to contaminating microorganisms. During cultivation, it effectively inhibits the growth of common contaminating microorganisms such as *Trichoderma* and *Vibrio vulgaris*, significantly reducing the contamination rate and improving the cultivation success rate.

[0022] Fruiting body morphology characteristics: The fruiting body morphology of the new Hericium erinaceus strain Finc-H-1 is as follows Figures 3 to 5 As shown, the fruiting body is round or obovate, plump in shape, and usually 8-15cm in diameter. The spines are of moderate length, about 1-3cm, evenly distributed and firm in texture. The color is pure white like jade, turning slightly yellow when mature, and the overall appearance is very beautiful.

[0023] Fruiting body yield: Multiple comparative experiments showed that, under the same cultivation conditions, there was no significant difference in fruiting body yield among different batches of the new Hericium erinaceus strain Finc-H-1, and the yield was very stable. Taking an 850mL cultivation bottle as an example, each bottle (180g dry material weight) can produce 127g of fresh Hericium erinaceus, with a bioconversion rate as high as 70.6%.

[0024] Fruiting body quality: The fruiting bodies of Hericium erinaceus produced by the Finc-H-1 strain are firm, crisp, tender, delicious, and rich in flavor. Furthermore, the fruiting bodies of Hericium erinaceus produced by this strain can be stored for 3-5 days at room temperature and 7-10 days under refrigeration (4℃), demonstrating excellent preservation properties.

[0025] Based on the above description, the present invention also protects a Hericium erinaceus spore, which is the spore obtained after culturing the Hericium erinaceus strain Finc-H-1.

[0026] This invention also protects a Hericium erinaceus protoplast, which is the protoplast obtained after culturing the Hericium erinaceus strain Finc-H-1.

[0027] This invention also protects a type of Hericium erinaceus mycelium, which is the mycelium obtained by culturing the Hericium erinaceus strain Finc-H-1.

[0028] This invention also protects a fruiting body of Hericium erinaceus, obtained for cultivating the above-mentioned Hericium erinaceus strain Finc-H-1.

[0029] To further highlight the advantages of the Hericium erinaceus strain provided by this invention, the following experiments provide a more detailed comparative explanation of the strain and its applications.

[0030] Example 1: Factory cultivation experiment of a new strain of Hericium erinaceus, Finc-H-1

[0031] This invention employs a factory-scale, year-round bottle cultivation model, using 850mL dedicated cultivation bottles to conduct factory-scale cultivation experiments on the new strain Finc-H-1. Those skilled in the art will understand that cultivation bottles of different sizes can also be used for fruiting body culture of the strain; for example, 500mL or 1000mL cultivation bottles can be used, only requiring adjustment of the filling amount and perforation depth. Alternatively, plastic cultivation bags can be used instead of cultivation bottles for fruiting body culture of the strain; for example, 17cm × 35cm polypropylene bags can be used, each bag containing 500g of dry material.

[0032] The specific cultivation process is as follows:

[0033] (1) Cultivation preparation work:

[0034] Factory-style plant construction: A closed plant with excellent airtightness, insulation, and moisture resistance is constructed. The plant is divided into functional areas such as an inoculation area, cultivation area, fruiting area, and contamination area. The inoculation area maintains good dust protection, with smooth, corner-free interior walls and roof for easy cleaning. It is regularly disinfected and sterilized using purification devices such as ultraviolet lamps, ozone generators, high-efficiency air filtration systems, air showers, and laminar flow hoods, achieving an air cleanliness level of 10,000. The inoculation area reaches a class 100 cleanliness level. The cultivation area maintains constant temperature and humidity, is light-protected, has good air exchange capabilities, and is equipped with insect and rodent control measures. The fruiting area is equipped with comprehensive temperature control, humidification, ventilation, and lighting facilities, and the walls are moisture-proof. The contamination area is equipped with dust-proof spray facilities during production operations and maintains a safe distance from the sterile area.

[0035] Cultivation container selection: 850 mL polypropylene plastic bottles with a 6 cm diameter were selected as cultivation containers. These cultivation bottles have good stability and breathability, providing suitable space for the growth of Hericium erinaceus and facilitating mechanized operations.

[0036] Production equipment includes: professional mixing machines, automatic bottling machines, autoclaves, ultraviolet sterilization equipment, ozone generators, air filtration and purification equipment, temperature control equipment, humidification spray equipment, lighting equipment, and ventilation equipment. The autoclave must meet national mandatory requirements to ensure sterilization effectiveness.

[0037] (2) Cultivation substrate formula:

[0038] Raw material selection: Agricultural and forestry waste such as hardwood sawdust, oak sawdust, cottonseed hulls, corn cobs, soybean hulls, soybean residue, and rice bran are selected as cultivation materials, along with auxiliary materials such as corn flour, wheat bran, and gypsum. All raw materials must be fresh, free from insects, mold, and pesticide contamination.

[0039] Cultivation Substrate Formula: Through extensive experimentation and optimization, the inventors discovered that the following formulation of the cultivation substrate can achieve superior yield and quality for Hericium erinaceus. The cultivation substrate formula, by weight percentage, includes: 10%-15% hardwood sawdust (e.g., birch sawdust, poplar sawdust, etc.), 20%-25% oak sawdust, 10%-15% cottonseed hulls, 20%-25% corn cobs, 9%-12% rice bran, 9%-12% wheat bran, 5%-8% soybean hulls, 5%-10% soybean residue, 3%-5% corn flour, and 1%-2% gypsum. Corn cobs can be replaced with sugarcane bagasse, cotton stalk powder, etc., and rice bran can be replaced with wheat bran, rice bran residue, etc., achieving similarly good cultivation results.

[0040] (3) Cultivation experiment

[0041] Mixing: According to the cultivation substrate formula provided above, put all the raw materials into the mixing machine and mix them thoroughly. During the mixing process, slowly add an appropriate amount of water while mixing, until the moisture content of the substrate reaches 60%-65%. During the mixing process, a moisture meter or other equipment can be used to accurately detect the moisture content to ensure that the moisture content meets the requirements.

[0042] Bottling: Use an automatic bottling machine to fill the prepared culture medium into 850mL culture bottles. During bottling, ensure the medium is evenly distributed and appropriately packed, generally filling to the shoulder of the bottle. After bottling, use the accompanying perforation device to vertically punch holes in the center of the culture medium, with a hole diameter of approximately 1-1.5 cm and a depth reaching the bottom of the bottle. This increases the aeration of the culture medium, meeting the oxygen requirements for mycelial growth. Immediately after punching, cap the bottle with a dedicated cultivation bottle cap. This cap has ventilation holes and an internal cavity. The ventilation holes are located on both the outer and inner perimeter of the cap and are connected to the cavity. The cavity buffers, filters, and settles the air entering the bottle, preventing the entry of contaminants and allowing for a more gradual gas exchange between the inside and outside of the bottle, thus maintaining a stable microenvironment.

[0043] Sterilization: Arrange the culture bottles containing the culture medium and with the caps on neatly in an autoclave for sterilization. Sterilization conditions are: temperature 121℃, sterilization pressure 0.12-0.13 MPa, and sterilization time 90-120 minutes. During sterilization, temperature and pressure must be strictly controlled to ensure thorough sterilization and kill all microorganisms and their vegetative forms in the culture medium.

[0044] Inoculation: After sterilization, transfer the culture bottles to a sterile room and allow them to cool naturally to 18-22°C. Under sterile conditions, open the caps of the culture bottles and use an automatic inoculation machine to inoculate the surface of the culture medium with the new Hericium erinaceus strain Finc-H-1. The inoculation amount per bottle should be controlled at 5-8 g. After inoculation, quickly close the caps of the culture bottles to reduce contamination by other microorganisms.

[0045] Mycelial Culture: After inoculation, the culture bottles are transferred to the culture area for mycelial culture. The temperature in the culture area is controlled at 22-25℃, and the relative humidity is maintained at 60%-70%. Multi-layer shelves can be installed in the culture room to neatly place the culture bottles for three-dimensional cultivation, making full use of space. During the cultivation process, the environment should be kept dark, and regular ventilation should be maintained to ensure fresh air, while controlling the carbon dioxide concentration to not exceed 500 ppm. Generally, after 14-18 days, the mycelium will have completely covered the entire culture bottle. During this period, the culture bottles should be checked regularly, and contaminated bottles should be removed promptly to prevent the spread of contaminating microorganisms.

[0046] Fruiting induction: Once the mycelium has fully colonized the bottle and reached physiological maturity, transfer the cultivation bottle to the fruiting area for fruiting induction management. First, remove the top cap of the cultivation bottle. A fruiting hole with a diameter of 3-4 cm is made in the center of the bottom cap for the growth and emergence of the lion's mane mushroom fruiting bodies. The temperature in the fruiting area is controlled at 16-18℃, and the air humidity is maintained at 75%-85%. Cultivation is carried out in a completely dark cultivation room while maintaining good ventilation to ensure that the carbon dioxide concentration does not exceed 900 ppm.

[0047] Fruiting Management: After mushroom buds form, adjust the air humidity to 85%-90% and provide 1.5-2 hours of light daily to promote bud growth. As the fruiting bodies grow, gradually increase ventilation to ensure fresh air, but avoid strong winds blowing directly on the mushrooms, and keep the carbon dioxide concentration below 900 ppm. Regularly check the growth of the fruiting bodies and adjust environmental parameters as needed. Harvesting can begin when the fruiting bodies reach a diameter of 8-10 cm and the spines are 1-3 cm long. The entire fruiting cycle of the new Hericium erinaceus strain Finc-H-1 provided by this invention is generally 10-15 days.

[0048] Harvesting and Subsequent Management: When the fruiting bodies of the lion's mane mushrooms reach the harvesting standard, remove the bottom cap of the bottle and take out the fruiting bodies, taking care to keep the fruiting bodies as intact as possible and avoid damaging the mycelium on the surface of the culture medium. After harvesting, the lion's mane mushrooms should be graded and packaged in a timely manner, and can be sold fresh or processed into dried products, canned goods, etc., according to market demand.

[0049] Example 2: Spring Factory Bottle Planting Experiment

[0050] Following the industrialized cultivation method provided in Example 1, a new strain of Hericium erinaceus, Finc-H-1, was experimentally cultivated in spring. This strain served as the experimental group, and five batches were tested. Simultaneously, strain Hu Hou 28 was used as the control group, and industrialized cultivation experiments were conducted under the same conditions. Five batches of this strain were also tested.

[0051] The dry substrate formula is as follows: 12% hardwood sawdust, 22% oak sawdust, 10% cottonseed hulls, 21% corn cobs, 10% rice bran, 10% wheat bran, 6% soybean hulls, 5% soybean residue, 3% corn flour, and 1% gypsum. The moisture content of the substrate is controlled at around 62%, and the pH value of the prepared substrate is approximately 6.2.

[0052] Bottling and punching: Use an automatic bottling machine to fill the culture medium to the shoulder of the bottle, then punch a hole in the center of the culture medium. The hole should be 1.2 cm in diameter and reach the bottom of the bottle. After punching, put on a special cap with ventilation holes.

[0053] Sterilization: 121℃ high-pressure sterilization, sterilization pressure 0.125MPa, sterilization time 105 minutes.

[0054] Inoculation: After the culture medium in the culture bottle has cooled to 20°C, inoculate in a sterile room. Each bottle of the experimental group and the control group is inoculated with 6 g of bacterial culture.

[0055] Mycelial culture conditions: Culture temperature 23-24℃, relative humidity 65%, in the dark, with regular ventilation to maintain CO2 concentration below 500 ppm. The mycelium will fully colonize the bottle in about 16 days.

[0056] Inducing bud formation: Transfer the culture bottles covered with mycelium to the fruiting room, maintain the ambient temperature at 17℃, control the humidity at around 80%, cultivate in complete darkness, and control the CO2 concentration to less than 900 ppm.

[0057] Mushroom management: After the mushroom buds form, adjust the humidity of the mushroom growing room to 88%, provide 2 hours of light per day with a light intensity of 800 lx, maintain good ventilation, and control the CO2 concentration to less than 900 ppm.

[0058] Harvesting: Harvest when the fruiting body of the Hericium erinaceus reaches a diameter of 9 cm or more and the spines are longer than 2 cm.

[0059] The fruiting data for the two strains are shown in Table 1 below.

[0060] Table 1. Comparison of fruiting data from spring factory cultivation trials of Finc-H-1 and Huhou 28

[0061]

[0062] As shown in Table 1, in the five batches of fruiting trials of the new Finc-H-1 strain, the average yield was more stable and higher than that of Hu Hou 28. Under suitable conditions, the average yield of each batch of the new Finc-H-1 strain was over 120 g, with little variation in fruiting bodies between batches and within each batch, indicating strong consistency. In terms of contamination resistance, the new Finc-H-1 strain was also significantly superior to Hu Hou 28, indicating stronger resistance to contaminating microorganisms and higher economic benefits. Regarding shelf life, the fruiting bodies produced by the new Finc-H-1 strain had an average shelf life approximately two days longer than those produced by Hu Hou 28, demonstrating stronger preservation capabilities.

[0063] Example 3: Autumn Factory Bottle Planting Experiment

[0064] In this Example 3, the cultivation method is basically the same as in Example 2. Only minor adjustments were made to the substrate formula and the environmental parameters.

[0065] In the autumn factory-scale bottle cultivation experiment, the dry substrate formula was as follows: 12% hardwood sawdust, 22% oak sawdust, 10% cottonseed hulls, 20% corn cobs, 10% rice bran, 10% wheat bran, 6% soybean hulls, 5% soybean residue, 3% corn flour, and 2% gypsum. The moisture content of the substrate was controlled at around 61%, and the pH value of the prepared substrate was approximately 6.2.

[0066] In terms of cultivation environment parameters, the mycelium cultivation temperature was maintained at 24℃, the fruiting temperature was controlled at 16℃, and the environmental humidity was maintained at around 86%.

[0067] The remaining strains were cultivated using the same industrialized cultivation method as in Example 2. In autumn, the new Hericium erinaceus strain Finc-H-1 was used as the experimental group, and five batches were tested. Simultaneously, strain Hu Hou 28 was used as the control group, and industrialized cultivation experiments were conducted under the same conditions, with five batches also tested.

[0068] The fruiting data for the two strains are shown in Table 2 below.

[0069] Table 2 Comparison of fruiting data from autumn factory cultivation trials of Finc-H-1 and Huhou 28

[0070]

[0071] As shown in Table 2, in the autumn factory cultivation experiment, compared with Table 1, the fruiting of the new Finc-H-1 strain in the five batches in autumn was basically similar to that in spring, indicating that the new Finc-H-1 strain has good stability, is less affected by external environmental factors, and is suitable for large-scale factory cultivation. Specifically, in the autumn factory cultivation, the average yield of each batch of the new Finc-H-1 strain was over 120 g, which is more stable and higher than that of Huhou 28. The fruiting body differences between batches and between batches of the new Finc-H-1 strain are small, showing strong consistency. In terms of pollution resistance, the new Finc-H-1 strain also performs well, with stronger resistance to contaminating microorganisms and higher economic benefits. In terms of shelf life, the fruiting bodies produced by the new Finc-H-1 strain have a shelf life of 8-9 days at 4℃, demonstrating strong preservation ability.

[0072] In summary, the Hericium erinaceus strain Finc-H-1 provided by this invention exhibits excellent overall characteristics and broad market prospects, possessing the following advantages: The fruiting bodies cultivated from this strain have high yield per unit area, high bioconversion rate, and stable yield. Furthermore, this strain demonstrates strong resistance to contaminating microorganisms and higher environmental adaptability during cultivation, while also possessing the significant advantage of being easily cultivated in industrial settings.
