How to Make Liquid Culture for Mushroom Growing
Mushroom liquid culture is a crucial element in growing mushrooms because it helps you create a consistent supply of mushrooms with better yields. It means it’s an easy, efficient, and cost-effective way to produce high-quality mushrooms. Let’s deep dive into the step-by-step instructions on how to make mushroom-growing liquid culture.
Master the Art of Making Liquid Culture for Mushroom Growth
Prepare Your Work Area
Ensure that your work area is clean and sterile before you begin the process of making liquid culture for mushroom growth. Sterilize your tools and surfaces with rubbing alcohol or a 10% bleach solution.
Gather the Necessary Materials:
A pressure cooker to sterilize the containers and nutrient solution.
Syringes and containers to hold the liquid culture and transfer it from syringe or to other containers or substrates.
A nutrient-rich solution for the healthy growth of mycelium in the liquid culture.
Sterile needles to inject the mushroom spores or mycelium into the nutrient solution.

Choosing the Right Strain
The first step in making liquid culture for mushrooms is choosing the right strain of mushrooms. You can select the strain from a variety of options available, including shiitake, oyster, lion’s mane, and many others. Ensure to choose a strain that is compatible with liquid culture.
Preparing the Culture Medium
The next step is to prepare the culture medium. There are different types of media that can be commonly used to prepare mushroom liquid culture, but the most common is a mixture of malt extract and yeast extract. To prepare the medium, mix one-part malt extract, one part yeast extract, and ten parts of water in a sterilized jar. Ensure the jar has a self-healing injection port and a polypropylene lid.
The culture medium needs to be sterilized to eliminate any contaminants and microorganisms that can hinder the growth of the mushroom mycelium. Use a pressure cooker or autoclave to sterilize the jars containing the medium. The medium must reach a temperature of 15 PSI and maintain it for at least 45 minutes.
After sterilization, allow the jars to cool down to room temperature before inoculating them with spores or mycelium. To inoculate, create a small hole in the lid using a sterilized needle, then inject the spores or mycelium into the jar.
Once the jars are inoculated, keep them in a warm and dark place to allow the mycelium to grow. The ideal temperature for incubation is between 20 and 25°C. Check the jars daily for any signs of contamination, and if you discover any are present, discard the affected jars.
After a few days, the mycelium will start to grow in the culture medium. To quickly increase the amount of mycelium, you can transfer the culture medium into multiple jars, allowing it to grow further.
Liquid Culture Transfer
Once the mycelium has grown in the culture medium, it is time to transfer it into the liquid culture. To do this, sterilize a jar containing the liquid culture medium and inject the mycelium using a sterilized needle. Ensure to sterilize the needle before and after each use to prevent contamination.
Incubation and Shake
The jar containing the liquid culture and mycelium needs to be incubated for about two weeks to a week. During this time, the mycelium will grow and spread throughout the more liquid culture medium. To speed up the process, you can shake the jar gently every day.
Use of Liquid Culture for Mushroom Growth
After the mycelium has fully colonized the liquid medium, it is ready to be used as a spawn for mushroom cultivation. You can use the liquid culture to inoculate a substrate of your choice, such as sawdust grains, grain, or straw.
