Liquid Culture Syringe

How to Use Liquid Culture Syringes:

• Preparation:

  • Before using your liquid culture syringe, make sure all tools and surfaces are clean and sanitized to prevent contamination.

  • You may want to work in a clean environment such as a still air box, glove box, or under a laminar flow hood for optimal sterility.

• Inoculating Grain or Substrate:

  • Sterilize your grain jars or bags (e.g., rye, millet, or sawdust) before inoculating.

  • Shake the syringe gently to evenly distribute the mycelium in the liquid.

  • Draw the liquid culture into the syringe (usually 1-2ml per jar or bag).

  • Insert the needle through the sterilized lid or filter patch of your jar/bag, and inject the culture into the substrate. If you're using jars, consider placing the needle just below the surface to allow even distribution.

• Post-Inoculation Care:

  • Store your inoculated jars or bags in a warm (70-80°F / 21-27°C) and dark location to encourage mycelial growth.

  • Ensure your jars/bags have proper air exchange to allow the mycelium to breathe (especially if using bags with filter patches).

  • Check your jars regularly for signs of contamination (off-color growth or foul smell) and for full colonization of the substrate. Once colonized, your mycelium is ready for fruiting!

Storage Instructions:

• Short-Term: Store your liquid culture syringes in the refrigerator (36-40°F / 2-4°C) until you're ready to use them. This will help preserve the mycelium and prevent premature growth.

• Long-Term: For long-term storage, the syringes can remain in the fridge for up to 6 months. However, it’s recommended to use them within 1-3 months for the best results.

Tips for Success:

• Use a clean needle for each inoculation to avoid cross-contamination.

• For larger inoculations, you can shake the syringe to disperse mycelium into multiple jars or bags.

• If you’re having trouble with slow colonization, ensure that your substrate is properly sterilized and that the environment is warm and clean.
