Agar Cultivation
- Prepare the agar medium by mixing agar powder with water according to the manufacturer's instructions.
- Autoclave the agar medium to sterilize it and let it cool to around 50°C.
- Pour the agar medium into sterile petri dishes, filling them about halfway full.
- Allow the agar to solidify in the petri dishes in a sterile environment, such as a laminar flow hood.
- Inoculate the agar plates with a small piece of chestnut mushroom tissue or spores using sterile techniques.
- Seal the petri dishes with parafilm or tape and incubate them at the appropriate temperature for chestnut mushroom growth, typically around 25°C.
- Check the agar plates regularly for signs of contamination or growth of the chestnut mushroom mycelium.
- Once the chestnut mushroom mycelium has fully colonized the agar plates, you can use them to inoculate your substrate for fruiting.
Liquid Culture Cultivation
- Prepare the liquid culture medium by combining water, malt extract, and agar in a sterilized container.
- Mix the ingredients thoroughly and sterilize the medium using a pressure cooker or autoclave.
- Allow the medium to cool to room temperature before inoculating it with a small piece of chestnut mushroom mycelium.
- Seal the container with a breathable lid or cover to allow for gas exchange.
- Incubate the liquid culture at the optimal temperature for chestnut mushrooms to promote mycelium growth.
- Monitor the culture for signs of contamination and discard if any mold or bacteria growth is observed.
- Once the mycelium has fully colonized the liquid culture medium, it is ready to be used for inoculating substrate for mushroom cultivation.
