How To Make Liquid Culture

Making a liquid culture for mushrooms involves creating a nutrient-rich solution to promote the growth of mycelium. Here are the steps to create a basic liquid culture:

  1. Prepare your equipment: You will need a sterilized glass jar or flask, a sterilized lid or stopper with a small hole, and a pressure cooker or autoclave for sterilization.

  2. Prepare the nutrient solution: Mix together distilled or sterilized water with a nutrient source such as malt extract, potato dextrose, or agar. The ratio of nutrient to water will depend on the specific recipe you are following.

  3. Sterilize the solution: Pour the nutrient solution into the sterilized jar or flask and seal it with the sterilized lid or stopper. Place the container in a pressure cooker or autoclave and heat it to 15 psi for 15-20 minutes to sterilize the solution.

  4. Inoculate the solution: Once the solution has cooled, add a small amount of mycelium to the jar or flask. This can be done by transferring a small piece of colonized agar or by injecting spores into the solution using a sterilized syringe.

  5. Incubate the culture: Place the inoculated liquid culture in a warm, dark place and allow it to incubate. Depending on the species of mushroom, the culture may take anywhere from a few days to a few weeks to fully colonize.

  6. Use the liquid culture: Once the liquid culture has fully colonized, it can be used to inoculate other substrates such as grain or sawdust to create mushroom spawn.
